Purpose: This study investigates the effects of daily consumption of a probiotic ayran drink on gingival inflammation and the development of experimental gingivitis., Materials and Methods: This randomised, double-blind, placebo-controlled trial involved 54 volunteer students. The participants were randomly assigned to two groups: the control group received regular ayran for 42 days, while the test group received probiotic enriched ayran (including Lactobacillus acidophilus and Bifidobacterium bifidum) for 42 days twice a day. After 42 days, mechanical plaque control was stopped for 5 days. The plaque index (PI), gingival index (GI), probing bleeding (BOP), and probing depth (PPD) were measured at baseline, day 42, and day 47. At the same time, gingival crevicular fluid was taken for matrix metalloproteinase-8 examination., Results: The mean scores of BOP, GI, PI, and MMP-8 levels increases in both groups following the 5-day experimental gingivitis period compared to baseline and day 42. Patients using probiotic ayran had significantly less PI, GI, BOP scores and MPP-8 values (p = 0.002; p 0.001; p 0.001; p = 0.001; p = 0.001, respectively) at day 47 compared to the control group. No statistically significant differences in probing pocket depth (PPD) were observed at any time point., Conclusion: The present study suggests that daily consumption of a probiotic ayran drink containing Lactobacillus acidophilus and Bifidobacterium bifidum statistically significantly lowers clinical and immunological markers of gingival inflammation.

Objectives: This study aimed to evaluate the biological and clinical effect of professional toothbrushing on the periodontal health of patients with gingivitis., Methods: We enrolled 21 university students with gingivitis in Jinju City in this study between April 24 and October 28, 2014. A dental hygienist performed a professional toothbrushing routine on the participants twice, once at baseline and after 3 months. Oral examinations were performed at baseline, 3, and 6 months to assess the periodontal health. The patient hygiene performance index, gingival bleeding rate, periodontal pocket depth, amount of gingival sulcus fluid, and number of bacterial colonies in the gingival sulcus (CFU/mL) were evaluated during the oral examination., Results: The patient hygiene performance index, gingival bleeding rate, pocket depth, amount of gingival sulcus fluid, and CFU/mL within the gingival sulcus significantly decreased after professional toothbrushing (p < 0.05), indicating an improvement in the periodontal health. The patient hygiene performance index, gingival bleeding rate, pocket depth, amount of gingival sulcus fluid, and CFU/mL within the gingival sulcus decreased more among those whose pocket depth was 4-5 mm than among those whose PD was ≤3 mm (p < 0.05)., Conclusions: Professional toothbrushing improved the periodontal health in patients with gingivitis in respect of both biological and clinical results., (© 2023 John Wiley & Sons A/S.

Objective: To compare the effectiveness of three oral hygiene groups: a novel sonic-flosser toothbrush with a compact brush head, a novel sonic-flosser toothbrush with a full size brush head and manual toothbrush plus dental floss on the reduction of gingival bleeding after 4 weeks. Secondarily, the groups were compared on the reduction of gingival inflammation and dental plaque., Materials and Methods: One hundred and five (n = 105) healthy adults were enrolled in this randomized, examiner-blind, three-group, parallel clinical trial. Subjects were assigned to one of three groups: sonic-flosser toothbrush with full size brush head (SFF), sonic-flosser toothbrush with compact brush head (SFC), or manual toothbrush and string floss (MTF). Bleeding on probing (BOP), Modified Gingival Index (MGI), and Rustogi Modification of the Navy Plaque Index (RMNPI) scores were recorded at baseline, 2-weeks, and 4-weeks., Results: All subjects completed the study. All three groups demonstrated a significant reduction in BOP, MGI and RMNPI from baseline to 4-weeks for all areas recorded (p < 0.001), except gingival margin plaque scores for SFF, SFC and MTF (p = 0.203, p = 0.082, p = 0.324 respectively). Both the SFF and SFC groups were statistically more effective than MTF for whole mouth BOP, MGI and RMNPI (p < 0.001) and proximal areas (p = 0.022 or less). There were no adverse events reported by the subjects or identified by the examiner during the study., Conclusion: The sonic-flosser toothbrush with a full size or compact brush head was statistically and clinically more effective at improving gingival health and reducing plaque than manual toothbrush and dental floss for adults with naturally occurring gingivitis over 4-weeks., (© 2023 John Wiley & Sons Ltd.)

The prevalence of coeliac disease in the general population is 0.5%-1%; however, most patients remain undiagnosed until adult age. In some cases, the onset is represented by sub-clinical signs, some of which can be found in the mouth. The aim of this research was to identify any associations between the clinical characteristics of coeliac disease and oral manifestations. A structured questionnaire was administered to a group of 237 individuals with coeliac disease. 100% of the subjects fully completed the questionnaire. Among them, 182 (76.7%) were female, 64 patients (27%) were aged 15 to 24 years, 159 (67%) were aged 25 to 55 and 14 (6%) were aged 56 and over. Significant associations were observed in caries prevalence and dentin sensitivity; in addition, an inappropriate diet was related to oral manifestations; following a gluten-free diet could be important to control the gingival bleeding levels and to manage oral symptoms associated to coeliac disease. In general, the presence of inflammatory symptoms in the mouth seems to be associated with general symptoms of inflammation related to coeliac disease.

Purpose: The primary aim was to describe the effects for nursing home residents of monthly professional cleaning and individual oral hygiene instruction provided by registered dental hygienists (RDHs), in comparison with daily oral care as usual. The secondary aim was to study the knowledge and attitudes among nursing staff regarding oral health care and needs., Patients and Methods: In this randomised controlled trial (RCT), 146 residents were recruited from nine nursing homes in Regions of Stockholm and Sörmland and were randomly assigned (on nursing home level) to either intervention group (I; n=72) or control group (C; n=74). Group I received monthly professional cleaning, individual oral hygiene instructions and information given by an RDH. Group C proceeded with daily oral care as usual (self-performed or nursing staff-assisted). Oral health-related data was registered with the mucosal-plaque score index (MPS), the modified sulcus bleeding index (MSB), and root caries. The nursing staff's attitudes and knowledge were analysed at baseline and at six-month follow-up. Statistical analysis was performed by Fisher's exact test and two-way variance analysis (ANOVA)., Results: Improvements were seen in both Group I and Group C concerning MPS, MSB and active root caries. The nursing staff working with participants in Group I showed significant improvements regarding the Nursing Dental Coping Beliefs Scale (DCBS) in two of four dimensions, oral health care beliefs (p=0.0331) and external locus of control (p=0.0017) compared with those working with Group C. The knowledge-based questionnaire showed improvement ( p =0.05) in Group I compared with Group C., Conclusion: Monthly professional oral care, combined with individual oral health care instructions, seems to improve oral hygiene and may reduce root caries among nursing home residents. This may also contribute to a more positive attitude regarding oral hygiene measures among nursing home staff, as compared with daily oral care as usual., Competing Interests: Petteri Sjögren is employed by a dental company, Oral Care AB.

Aim: This study was designed to investigate the clinical and microbiological parameters with photochemotherapy (PCT) against conventional debridement (CD) among patients with necrotizing ulcerative gingivitis (NUG)., Materials and Methods: Patients with a diagnosis of NUG were divided into two groups: 'Group-PCT' that underwent indocyanine green-mediated PCT with adjunctive mechanical debridement, and Group-CD that underwent mechanical debridement with adjunctive 3 % hydrogen peroxide/chlorhexidine rinse. Clinical inflammatory gingival parameters including full-mouth plaque scores (FMPS), bleeding scores (FMBS), and probing depth (PD) were measured. Counts of Treponema microdentium, Fusobacterium nucleatum and Prevotella intermedia were assessed using polymerase chain reaction technique. All assessments were done at baseline, 3 weeks and 6 weeks., Results: Twenty-six participants were contacted and agreed to participate in the trial. The mean age of participants in group-PCT was 24.5 years while the mean age of patients in group-CD was 26.7 years. FMPS showed significant but equal reduction in both the groups at 3 weeks and 6 weeks (p < 0.01). The reduction in mean FMBS was higher in the group-PCT at 6 weeks follow-up (p < 0.05). All bacterial levels reduced from baseline to follow-up with both PCT and CD groups (p < 0.05). Group-PCT showed significantly reduced counts of T. microdentium and F. nucleatum at 3 weeks and 6 weeks compared with group-CD (p = 0.024). Equal reduction was shown for P. intermedia between both the groups at 3 and 6 weeks, respectively., Conclusion: Application of adjunctive photochemotherapy was both clinically and microbiologically effective in the treatment of NUG., Competing Interests: Declaration of Competing Interest The authors of the present study reports no conflict of interest., (Copyright © 2020 Elsevier B.V.

Background: In order to prove the idea that topical application of drugs can improve the clinical parameters affecting periodontal disease, a sound comparison should be made between topical therapeutic models. The aim of the present study was to assess the clinical efficacy of photodynamic therapy (PDT) and Salvadora persica (SP) gel as adjuncts to scaling and root planning (SRP) in the treatment of chronic periodontitis., Methods: The selected patients were divided into three groups, Group I (PDT + SRP), Group II (SP + SRP) and group III (SRP alone). Clinical inflammatory periodontal parameters including plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) gain were assessed. Assessment of crevicular fluid interleukin (IL)-6 and tumor necrosis factor alpha (TNF-α) was performed using enzyme-linked immunosorbent assay technique. All measurements were recorded at baseline, 3 months and 6 months follow-up periods, respectively., Results: A total of 73 patients completed the study. A significant improvement in the BOP was seen in Group II at both follow up visits when compared with other groups (p < 0.05). Only in Group-I that showed statistically significant reduction in moderate periodontal pockets at 3 months (p = 0.021), and significant reductions in deep pockets at 3-months (p = 0.003) and 6-months (p = 0.002), respectively. CAL gain also was reported to be seen in group-I at both visits (p < 0.05). Group- I and II significantly reduced the levels of IL-6 at 3-month period compared to Group-III. This reduction was further maintained by group-II and group-III at 6 months, respectively. TNF-α showed statistically significant decrease in Group II as compared to Group I and Group-III and this reduction was maintained by the end of 6-month visit (p = 0.045)., Conclusion: Both the treatment modalities PDT and SP helped in reducing periodontal inflammation. PDT reported significant gain in clinical attachment level, whereas the SP significantly reduced the bleeding levels., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2020 Elsevier B.V.

Glanzmann thrombasthenia (GT) is a rare genetic disorder that alters platelet function. The clinical manifestations include purpura, epistaxis, gingival bleeding, and menorrhagia. For patients with GT, conventional surgical dental treatment may result in hemorrhagic complications. There are many reported ways to prevent hemorrhage in patients with GT during surgical procedures but no standardized recommendations. In this case study, a woman diagnosed with GT required 2 types of surgery (periodontal surgery and third molar extractions), which were performed on separate days. Preoperative evaluation and planning with a hematology service led to the transfusion of 1 pack of platelet concentrate immediately before each surgery. Additionally, the patient was prescribed oral tranexamic acid, which was started 1 day before each surgery and continued for 3 additional days. A distal wedge procedure was performed for the mandibular right third molar, and later the maxillary and mandibular left third molars were extracted. The use of oral tranexamic acid associated with a single platelet bag was effective in the present case, and no bleeding or thrombotic events were observed after either surgery. Although this coagulopathy is rare, dentists must be aware of its implications, which necessitate specific precautions for oral surgical procedures. Multidisciplinary integration and surgical planning can reduce the risk of complications for the patient.

Clinical research on herbal-based dentifrice +/- mouth rinse products is very limited compared with the plethora of research on conventional oral care products under normal oral hygiene conditions. The aim of this study was to determine the anti-inflammatory effects of a novel plant Carica papaya leaf extract (CPLE) on interdental bleeding in healthy subjects. In this randomized, single-blind parallel-design study, the eligible subjects were generally healthy non-smokers, aged 18⁻26, who exhibited healthy periodontal conditions upon study entry. The participants were equally randomized into the following four groups: CPLE dentifrice, CPLE dentifrice and mouthwash, sodium lauryl sulfate (SLS)-free enzyme-containing dentifrice and SLS-free enzyme-containing dentifrice with essential oil (EO) mouthwash. Subjects were instructed to brush their teeth twice a day without changing their other brushing habits. Interdental bleeding (BOIP) was measured from inclusion (T₀) until the fourth week (T₄) of the study. Clinical efficacy was assessed after one, two, three and four weeks of home use. The analyses compared BOIP between groups and were then restricted to participants with ≥70% and then ≥80% bleeding sites at T₀. Pairwise comparisons between groups were performed at T₀ and T₄, and a logistic regression identified correlates of gingival bleeding (T₄). Among 100 subjects (2273 interdental sites), the median percentage of bleeding sites per participant at T₀ was 65%. The bleeding sites dramatically decreased in all groups between T₀ and T₄ (relative variations from -54% to -75%, p < 0.01 for all). Gingival bleeding did not significantly differ between the CPLE dentifrice and the SLS-free dentifrice +/- EO mouthwash groups (from p = 0.05 to p = 0.86), regardless of the baseline risk level. Among the CPLE dentifrice users, fewer bleeding sites were observed when toothpaste and mouthwash were combined compared to bleeding sites in those who used toothpaste alone (21% vs. 32%, p = 0.04). CPLE dentifrice/mouthwash provides an efficacious and natural alternative to SLS-free dentifrice +/-EO-containing mouthwash when used as an adjunct to mechanical oral care to reduce interdental gingival inflammation.

Purpose: To investigate the anti-gingivitis efficacy of a novel oral hygiene routine consisting of a two-step stannous fluoride dentifrice and hydrogen peroxide whitening gel system, an interactive oscillating-rotating electric toothbrush, and expanded polytetrafluoroethylene floss. Methods: A total of 52 participants (n=52;mean age 35.8±11.23 years) were enrolled in the study and randomized 1:1 to the experimental hygiene group or control (dental prophylaxis followed by use of standard sodium fluoride dentifrice and a manual toothbrush). Participants were instructed to brush twice daily; those in the experimental group were instructed to floss once daily. Oral examinations were conducted at Baseline, Week 2, Week 4, and Week 6. Results: Both groups experienced significant declines in the mean number of bleeding sites from Baseline at all time points, evident as early as Week 2. Bleeding sites continued to decline throughout the trial in the experimental group, whereas they showed an increasing trend between Weeks 2 and 6 in the control group. The experimental group had 55% fewer bleeding sites at Week 2, 85% fewer bleeding sites at Week 4, and 98% fewer bleeding sites at Week 6 ( p <0.0001 for all) as compared to the control group. At Week 6, 84% of participants in the experimental group had no bleeding, while all participants in the control group had bleeding. Conclusion: The experimental oral hygiene group showed significantly greater reductions in gingival bleeding than the control oral hygiene group, with benefits seen as early as Week 2 and increasing over the six-week study., (Copyright © 2018 The American Dental Hygienists’ Association.)

Aim: To determine the efficacy of a rubber bristles interdental cleaner (RBIC) compared to an interdental brush (IDB) in reducing gingivitis and additionally to evaluate participants' attitudes and possible side effects., Material and Methods: The study was a 2-treatment, parallel, split-mouth, examiner-blind RCT, evaluating the reversal of experimental gingivitis. In total, 42 systemically healthy volunteers were recruited that were currently non-users of interdental cleaning devices. After familiarization and prophylaxis, participants refrained from brushing mandibular teeth for 21 days, followed by 4-week product use of the assigned interdental cleaning device as adjunct to manual toothbrushing. Bleeding on marginal probing (BOMP), dental plaque index score (PI) and gingival abrasion score (GAs) were assessed in the lower jaw., Results: Overall, no statistically significant differences between the RBIC and IDB in reducing BOMP and PI were obtained. Analysing the sites that were accessible for the RBIC/IDB only showed that the sites treated with the RBIC had significantly less BOMP after 4 weeks (P = .009). The RBIC also caused less GAs (P => .016) and was considered more pleasurable to use by the participants (P = .0001)., Conclusions: In accessible sites, the RBIC, in conjunction with manual toothbrushing, was found to be more effective in reducing gingival inflammation after 4 weeks. The RBIC caused less abrasion of the gingiva and was appreciated more by the participants., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: To determine the efficacy of 4 different oral hygiene regimens involving adjunctive interdental cleaning devices in unsupervised young subjects with intact interdental papilla., Material and Methods: Sixty periodontally healthy subjects were randomly allocated to 4 groups following different oral hygiene regimens (T-7): use of manual toothbrush alone; manual toothbrush plus dental floss; manual toothbrush plus interdental brushes; and manual toothbrush plus rubber interdental picks. Oral hygiene instructions (OHI) were given. One week after (T0), professional supragingival scaling and polishing was performed, and subjects were then reseen every 2 weeks (T14 and T28). At T-7, T0, T14 and T28, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS) and angulated bleeding index (AngBI) were taken., Results: During the first week (T-7/T0 unclean phase), FMPS decreased significantly in all groups except the group using dental floss. At T28, a significant decrease in FMPS (P < .001, all groups) and FMBS (P < .05, all groups except the group using flossing P < .001) was noted. Interdental FMPS showed significantly lower values in subjects treated with interdental brushes or rubber interdental picks vs toothbrushing alone (P < .05). The use of interdental picks was associated with reduced interdental FMBS when compared to flossing (P < .05)., Conclusion: In young subjects, with no interdental attachment loss, toothbrushing or toothbrushing and adjunctive interdental cleaning devices such as dental floss, interdental brushes or interdental rubber picks can significantly reduce both plaque and gingival inflammation. Use of interdental brushes or rubber picks reduces more interdental plaque in comparison with toothbrushing alone., (© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: It is well-known that poor oral hygiene during orthodontic treatment may lead to development of gingivitis, probing pocket depth, hyperplastic tissue, decalcification, dental caries and white spot lesions on the coronal surfaces of teeth., Methods: Twenty-two patients with the following inclusion criteria were enrolled in the present study: fixed orthodontic treatment, age 12-18 years, systemically healthy, no history of periodontal treatment, periodontal health or gingivitis. The following clinical parameters were collected: periodontal screening and recording, plaque control record, and bleeding on probing. Oral hygiene instructions were given and a specifically designed technique for orthodontic patients was suggested. Complete information about the mechanical interdental device were also provided. Means and standard deviations or medians and interquartile ranges for each parameter were collected., Results: There was a statistically significant reduction in plaque control record on both sides. The reduction in the experimental group was significantly greater compared to controls after adjusting for baseline values. There was also a statistically significant reduction in bleeding on probing in the experiment group, but not in controls., Conclusions: The combination of manual toothbrush and mechanical interdental device demonstrated a better plaque control and gingival inflammation levels in orthodontic patients compared to manual brushing alone.

Objectives: The aim of this study was to investigate whether twice-daily use of a rotating-oscillating power toothbrush (Oral-B Professional Care 1000 ™ ) in nursing home (NH) residents over a 6-week period, compared to usual care (UC), would reduce periodontal inflammation., Methods: In this repeated measures single-blinded randomized controlled trial, 59 residents of one NH in Winnipeg, Canada, were randomized to receive either twice-daily tooth brushing with a rotating-oscillating power toothbrush (PB) or UC by caregivers. Consent was obtained from residents or their proxies. Participants had some natural teeth, periodontal inflammation, non-aggressive behaviour, no communicable diseases, were non-smokers and non-comatose. Outcomes were measured at baseline and 6 weeks, which included: inflammation (MGI, Lobene), bleeding (PBI, Loesche) and Plaque (Turesky). Comparisons of group changes in outcomes were analysed using an ANOVA with a repeated measure., Results: Of 59 original study participants, one withdrew, one died prior to study commencement and three died before study completion. All oral parameters improved significantly for the remaining 54 residents over time (P<.0001), with no differences between groups., Conclusions: These results demonstrate that it is possible for caregivers to improve periodontal inflammation of residents over a 6-week period. Despite no significant group differences, periodontal inflammation of all study participants improved significantly, particularly in the reduction of bleeding, a direct measure of periodontal inflammation, which is a unique finding., (© 2017 John Wiley & Sons A/S.

Background: The aim of the study was to evaluate the effectiveness of a chitosan brush on the treatment of mild peri-implantitis., Methods: Fifteen patients diagnosed with mild peri-implantitis contributing with single implant were treated with a chitosan brush. Modified plaque index (mPll), Modified Bleeding Index (mBoP) and probing depth (PPD) were recorded at baseline, 2, 4, 12 and 24 weeks. Chitosan brush was used at 12 weeks if diagnosis was still present. Periapical radiographs were taken at the beginning of the study and 6 months after to control the stability of bone level., Results: None of the patients reported discomfort or side effects during treatment. Bone level was maintained stable during the entire study. Plaque index remained almost 0 at every control visit. PPD and mBoP were significantly reduced at 2 weeks and when compared to baseline. At 24 weeks 73% of patients presented no further bleeding on probing with stable bone level., Conclusions: Chitosan brush could be a reliable instrument for the professionally administered plaque removal and resolution of clinical signs of initial stages of peri-implant inflammation.

Purpose: To test the hypothesis that, in high caries-risk children, supervised toothbrushing (STB) reduces visible plaque levels and gingival bleeding to a greater extent than does unsupervised toothbrushing (USTB) in comparable children and in low caries-risk USTB children over 4 years., Materials and Methods: High caries-risk schoolchildren, ages 6 to 7, were allocated to three oral healthcare protocols using a cluster-randomised design: 1. Ultra-Conservative Treatment (UCT): small cavities in primary molars were restored using ART, while medium and large cavities were left open and cleaned under daily supervised toothbrushing together with the remaining dentition (UCT/STB); 2. Conventional Restorative Treatment (CRT): primary molars were restored with amalgam, while high caries-risk first permanent molars received resin sealants (CRT/USTB); 3. Atraumatic Restorative Treatment (ART): primary molars were restored using ART, while high caries-risk first permanent molars received ART sealants (ART/USTB). Low caries-risk children (dmft ≤ 1) formed the no-treatment/USTB group. 273 children were examined at baseline (T0) and after 4 years (T1) according to the VPI and GBI indices. Data were analysed using linear and logistic regression., Results: Mean VPI and mean GBI scores were statistically significantly lower at T1 than at T0. Reduction in mean VPI scores in UCT/STB children was statistically significantly higher than for CRT+ART/USTB children over 4 years (p = 0.03), but no difference was observed between UCT/STB and no-treatment/USTB children (p = 0.361). No statistically significant difference in the reduction of mean GBI scores was observed between UCT/STB and CRT+ART/USTB (p = 0.62) and no-treatment/USTB children (p = 0.74)., Conclusion: In high caries-risk children, the protocol based on supervised toothbrushing presented greater reduction in visible plaque levels than did protocols based on restorations and sealants over 4 years.

Background: Periodontal disease is one of the most common chronic infectious diseases. It has been reported that periodontal disease is associated with various adverse pregnancy outcomes including preterm birth, low birth weight, and gestational diabetes mellitus. Given the fact that the treatment for periodontal disease during pregnancy was ineffective in improving pregnancy outcomes by most of studies, the pre-conception period has been put forward as a more optimal time. However, very few studies have reported the prevalence of periodontal disease among pre-conception women. This study aimed to examine the prevalence and risk factors of periodontal disease among Chinese pre-conception women., Methods: A survey was conducted among pre-conception women at the Maternal and Child Health Hospital, Changzhou, China between January 2012 and December 2014. A total of 987 pre-conception women were recruited for a full-mouth dental examination after providing informed consent. A dental examination was carried out by probing six sites per tooth using a manual UNC-15 probe and a recording form., Results: The overall rate of periodontal disease among participants was 73.9% (729/987) (95% confidence interval (CI): 71.0-76.6%). Among women with periodontal disease, 48.0% of cases were mild, 50.9% were moderate and 1.1% were severe. Self-reported bleeding during tooth brushing was the only significant predictive factor for overall periodontal disease (adjusted odds ratio (aOR): 3.71, 95% CI: 2.24, 6.15, P < 0.001) and moderate/severe periodontal disease (aOR: 5.17, 95% CI: 3.05, 8.79, P < 0.001)., Conclusion: A high prevalence of periodontal disease was found in pre-conception Chinese women. Women who have bleeding during tooth brushing could be at increased risk of periodontal disease, and might require further oral health care.

Purpose: To compare the anti-gingivitis effect of a power toothbrush relative to a manual toothbrush control., Methods: This was a 3-month, randomized and controlled, single-center, parallel group, examiner-blinded clinical study. 123 Chinese adults in good general health and with at least 15 gingival bleeding sites, as measured by the Gingival Bleeding Index, were enrolled into the study. At baseline, pre-treatment gingivitis levels were assessed using the Mazza Bleeding Index. Subjects were then randomly assigned to receive either an oscillating-rotating power toothbrush [Oral-B Professional Care 7000 (D17u/EB17)] or a flat-trim manual toothbrush with tapered filaments (Lion Dentor Systema). Subjects brushed at home twice-daily with their assigned toothbrush and a marketed sodium fluoride dentifrice (Crest Cavity Protection dentifrice), and were reevaluated at Months 1, 2, and 3., Results: 113 evaluable subjects completed the study. Both groups showed significant reductions in gingivitis from baseline for all time points measured (P< 0.001). At Months 1, 2 and 3, the power toothbrush demonstrated significantly greater gingivitis reductions of 7.11%, 9.20% and 8.47%, respectively, than the manual toothbrush (P< 0.01), and significantly fewer bleeding sites (17.3%, 23.9% and 24.3%, respectively, P< 0.05). No adverse events were reported or observed for either brush during the study., Clinical Significance: The power brush provided statistically significantly greater reductions in gingivitis compared with a manual toothbrush at Months 1, 2 and 3., Competing Interests: Dr. Z. Li and Dr. Zhao declared no conflict of interest. Dr. T. He, Ms. C. Li, Ms. Sun, Ms. Chang, Ms. Y. He, and Mr. Ji are employees of the Procter & Gamble Company.

The use of an immediately placed provisional restoration that mirrors the cervical contours of the extracted tooth at the time of implant placement may provide a platform to promote peri-implant soft tissue healing. This study examined the association of sulcular bleeding at the time of initial disconnection of the provisional restoration with stability of the buccolingual ridge dimension following immediate implant placement. Eighteen immediate implants grafted with particulate bone were restored with a screw-retained, single-unit, provisional restoration and abutment. The presence of sulcular bleeding was recorded after 5 to 7 months of healing. Stability of the buccolingual ridge dimension at the level of the free marginal gingiva and 1, 2, 3, 5, 7, and 9 mm apical was estimated using the contralateral tooth as a control. Gingival bleeding was associated with the disconnection of the provisional restoration in 11 (61.1%) of the grafted implant sites. Bleeding upon initial disconnection of the provisional restoration was significantly correlated with smaller changes, or greater stability, in the buccolingual ridge dimension at each reference point from 0 to 3 mm apical to the free gingival margin. The use of anatomically contoured provisional restorations may provide a platform to promote peri-implant soft tissue healing and minimize remodeling of the buccolingual ridge dimension.

Background: Numerous studies have documented the clinical outcomes of laser therapy for untreated periodontitis, but very few have reported on lasers treating inflamed pockets during maintenance therapy. The aim of this study is to compare the effectiveness of scaling and root planing (SRP) plus the adjunctive use of diode laser therapy to SRP alone on changes in the clinical parameters of disease and on the gingival crevicular fluid (GCF) inflammatory mediator interleukin-1β (IL-1β) in patients receiving regular periodontal maintenance therapy., Methods: This single-masked and randomized, controlled, prospective study includes 22 patients receiving regular periodontal maintenance therapy who had one or more periodontal sites with a probing depth (PD) ≥ 5 mm with bleeding on probing (BOP). Fifty-six sites were treated with SRP and adjunctive laser therapy (SRP + L). Fifty-eight sites were treated with SRP alone. Clinical parameters, including PD, clinical attachment level (CAL), and BOP, and GCF IL-1β levels were measured immediately before treatment (baseline) and 3 months after treatment., Results: Sites treated with SRP + L and SRP alone resulted in statistically significant reductions in PD and BOP and gains in CAL. These changes were not significantly different between the two therapies. Similarly, differences in GCF IL-1β levels between SRP + L and SRP alone were not statistically significant., Conclusion: In periodontal maintenance patients, SRP + L did not enhance clinical outcomes compared to SRP alone in the treatment of inflamed sites with ≥ 5 mm PD.

Data Sources: Medline, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL)., Study Selection: Randomized controlled trials (RCTs) or controlled clinical trials (CCTs) in adults 18 years of age comparing CHX DF/gel with CHX MW written in English or Dutch were considered., Data Extraction and Synthesis: Two reviewers independently selected studies, abstracted data and assessed risk of bias. Where possible, a meta-analysis was performed. Difference in means values between test and control at both baseline and end was calculated using a fixed-effects model., Results: Five RCTs were included, four had a parallel design and one was a cross-over trial. Three studies showed a positive score in favour of the mouthwash. Three studies contributed to a meta-analysis of the effect on 'de novo' plaque formation. There was a difference in means of 0.27 [95% CI: 0.14; 0.39] (P < 0.0001) in favour of CHX MW. One study assessed tooth staining finding more staining with the use of CHX MW compared to the CHX DF/gel., Conclusions: Chlorhexidine gel can be successfully formulated and will inhibit plaque growth to some degree, but not to the same extent, as a CHX MW. When CHX DF/gel is used in a non-brushing model, it is significantly less effective in plaque inhibition compared to CHX MW. Based on one study when CHX gel was applied with a finger after brushing, it is significantly more effective on plaque scores and the gingival index. The only brushing study also with a long follow-up showed that there is no significant difference between CHX DF and CHX MW. However, as a corollary, significantly more tooth discoloration was observed with the CHX MW. Altogether, the data show that when daily oral hygiene cannot be performed, CHX MW is the first product of choice.

Demineralizations around orthodontic brackets are a main disadvantage of orthodontic treatment. Several methods have been advocated to prevent their development, such as fluoride rinses or varnishes. In this randomized clinical trial, a fluoride rinse (a combination of sodium fluoride and amine fluoride) was compared with a placebo rinse, to be used every evening after toothbrushing. A total of 81 participants (mean age: 13.3 yr) completed the study (mean treatment period: 24.5 months). Demineralizations, measured using quantitative light-induced fluorescence and the decayed, missing, and filled surfaces (DMFS) index, were assessed before treatment (baseline) and around 6 wk after debonding (post treatment). Bleeding scores were measured at baseline, and during and post treatment. The incidence rate ratio for demineralizations was 2.6 (95% CI: 1.1-6.3) in the placebo group vs. the fluoride group. In the fluoride group, 31% of participants developed at least one demineralization, compared with 47% in the placebo group. Relative to baseline, gingival bleeding increased significantly in the placebo group 1 yr after the start of treatment and onwards. For the fluoride group, bleeding scores during treatment were not different from those at baseline. In conclusion, using a fluoride rinse helps to maintain better oral health during fixed appliance treatment, resulting in fewer demineralizations., (© 2015 The Authors.

Objective: To evaluate the effectiveness of 0.07% cetylpyridinium chloride (CPC) mouth rinse for reduction of gingival inflammation and inhibition of plaque compared to a vehicle control (VC) mouth rinse over a 6-month period., Materials & Methods: Participants (n = 62) used their randomly assigned product as adjunct to toothbrushing. Bleeding, plaque and staining scores were assessed at baseline, 3 and 6 months. Plaque and saliva samples were taken at each assessment monitoring possible shifts in the composition of the microbiota., Results: A significant difference (P = 0.002) in favour of the CPC mouth rinse, with respect to plaque scores, was found. Bleeding scores at 6 months were not significantly different (P = 0.089). However, when correcting for baseline values, a tendency towards a significant difference in bleeding scores at end trail was observed in favour of the CPC mouth rinse (P = 0.061). Regarding staining at 3 and 6 months, a small but significant difference (8.6% and 10.4%, respectively) (P < 0.0001) was observed with lower scores for the VC group. There was a significant reduction in total anaerobic count in the CPC group at 6 months (P < 0.05). The ratio of aerobes/anaerobes was markedly increased at 3 months, especially in the CPC group. No further differences were observed between groups at 6 months., Conclusions: The use of 0.07% CPC mouth rinse was significantly more effective in reducing plaque scores than the vehicle control. Bleeding scores were not different at 6 months. The test product was well accepted and did not cause any serious clinical side effects or negatively affected the microbiota., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: To systematically review and evaluate the available scientific evidence on the effectiveness of chlorhexidine dentifrice or gel (CHX DF/gel) compared to chlorhexidine mouthwash (CHX MW) on plaque, bleeding, gingival inflammation and tooth discoloration scores., Material and Methods: PubMed-MEDLINE, Cochrane-CENTRAL and EMBASE databases were searched to identify appropriate studies., Results: Independent screening of the 2256 unique titles and abstracts resulted in five publications that met the eligibility criteria. Considerable heterogeneity was found between the studies. Three of the five studies showed a positive effect on plaque scores in favour of the CHX MW. With respect to gingival index and bleeding scores, no significant differences were found. Chlorhexidine mouthwash, however, showed a significantly more tooth discoloration than the CHX DF/gel. A meta-analysis of the effect on 'de novo' plaque formation of CHX DF/gel versus CHX MW resulted in a difference in means of 0.27 [95% CI: 0.14; 0.39] (P < 0.0001)., Conclusion: Chlorhexidine gel can be successfully formulated and will inhibit plaque growth to some degree, but not to the same extent, as a CHX MW. When CHX DF/gel is used in a non-brushing model, it is significantly less effective in plaque inhibition compared to CHX MW. Based on one study when CHX gel was applied with a finger after brushing, it is significantly more effective on plaque scores and the gingival index. The only brushing study also with a long follow-up showed that there is no significant difference between CHX DF and CHX MW. However, as a corollary, significantly more tooth discoloration was observed with the CHX MW. Altogether, the data show that when daily oral hygiene cannot be performed, CHX MW is the first product of choice., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Aim: To update previous systematic review investigating effect of professional mechanical plaque removal (PMPR) on prevention of periodontal diseases., Methods: Search for randomized controlled trials: 2004 to April 2014. Screening and data abstraction conducted independently/in duplicate and narrative synthesis., Results: From 1655 titles and abstracts, 24 full-text articles screened and three new studies were eligible. Low-to moderate strength of evidence suggests that in adults, PMPR, particularly if combined with oral hygiene instructions (OHI), may achieve greater changes in measures of dental plaque and gingival bleeding/inflammation than no treatment. Moderate strength of evidence suggests there is no additional benefit to plaque and gingival bleeding outcomes from PMPR over that achieved by repeated and thorough OHI. There is no evidence from RCTs to inform on prevention of periodontitis. Low strength of evidence suggests that more frequent PMPR is associated with improved plaque and bleeding outcomes and possibly less annual attachment loss., Conclusions: There are insufficient data to inform directly on the effect of PMPR on primary prevention of periodontitis. However, in relation to gingival health, new studies strengthen the evidence that there is little value in providing PMPR without OHI. In fact, repeated, thorough OHI can achieve a similar benefit to repeated PMPR., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objective: The purpose of this study was to compare the reduction of the clinical signs of inflammation by two power interdental cleaning devices combined with a manual toothbrush., Methods: Sixty-nine subjects completed this randomized, four-week, single-blind, two-group, parallel clinical study. Subjects were randomly assigned to one of two treatment groups: Waterpik Water Flosser (WF) plus a manual toothbrush; or Sonicare Air Floss Pro (AFP) plus a manual toothbrush. All subjects received both written and verbal instructions and demonstrated proficiency prior to starting the study. Instructions were reviewed at the two-week visit (W2). Data were evaluated for whole mouth, lingual, and facial areas for bleeding on probing (BOP) and Modified Gingival Index (MGI). Plaque data were recorded for whole mouth, lingual, facial, approximal, and marginal areas of the tooth using the Rustogi Modification of the Navy Plaque Index (RMNPI). BOP, MGI, and RMNPI were scored at baseline (BSL), two weeks, and four weeks (W4)., Results: Both groups showed significant reductions in BOP and MGI from baseline for all regions and time points measured (p < 0.001). Both groups showed significant reductions from baseline for all areas at W4 for RMNPI (p < 0.001). The WF group was significantly more effective than the AFP group at reducing bleeding and gingivitis for all areas measured at all time points. At W4, the WF group was 54% more effective for bleeding and 32% for gingivitis (p < 0.001). Plaque accumulation was significantly less at W4 for the WF group compared to the AFP group (28%, p 0.017)., Conclusions: The Waterpik Water Flosser is significantly more effective than the Sonicare Air Floss Pro for reducing clinical signs of inflammation.

Background: Reactive oxygen species might be associated with the onset and progression of gingival inflammation. The aim of this study is to investigate the effect of a dentifrice containing L-ascorbic acid 2-phosphate magnesium salt (APM), a long-acting ascorbic acid derivative with antioxidant properties, on gingival inflammation., Methods: The clinical effects of APM were investigated in a multicenter, randomized, parallel-group, controlled clinical trial comprising 300 individuals with gingivitis. Half of the participants were given an APM-containing dentifrice and half were given a control dentifrice. The primary outcome was the gingival index (GI) at 3 months. Secondary outcomes included gingival redness as an indicator of the degree of local gingival inflammation, gingival bleeding as a measure of the gingivitis severity index, and total antioxidant activity of the saliva., Results: Under the intent-to-treat analysis, GI did not significantly differ between the groups (P = 0.12). However, under the per-protocol analysis, GI was significantly lower in the APM group (P = 0.01) than in the control group. In the APM group, gingival redness was significantly lower, and the difference from the baseline gingivitis severity index was significantly greater (P = 0.04 and P = 0.02, respectively). The total antioxidant activity of the saliva was significantly higher in the APM group (P = 0.03). The incidence of adverse events did not significantly differ between the groups (P > 0.15)., Conclusion: These findings indicate that the regular application of an APM-containing dentifrice could reduce gingival inflammation.

Objective: To evaluate and compare the efficacy of an oscillating-rotating (O-R) power toothbrush with a brush head utilizing angled bristles to a marketed sonic toothbrush in the reduction of plaque and gingivitis over an eight-week period., Methods: This study used a randomized, examiner-blind, single-center, two-treatment, parallel group, eight-week design. Subjects with mild-to-moderate plaque and gingivitis were evaluated for baseline whole mouth, gingival margin, and approximal plaque, gingivitis, and gingival bleeding. Clinical assessments were performed using the Modified Gingival Index, Gingival Bleeding Index, and the Rustogi Modified Navy Plaque Index. Subjects received either the O-R brush (Oral-B Professional Care 1000 [D16u] with Oral-B CrossAction brush head [EB50]) or the sonic brush (Sonicare DiamondClean with the standard DiamondClean brush head). Subjects brushed twice daily for two minutes per brushing with the assigned brush and a standard fluoride dentifrice for eight weeks before returning for plaque and gingivitis evaluations using the same methods. Prior to baseline and Week 8 measurements, participants abstained from oral hygiene for 12 hours., Results: One hundred and forty-eight subjects completed the study; 75 in the O-R group and 73 in the sonic group. Both brushes demonstrated statistically significant reductions in plaque and gingivitis over the eight-week study period (p < 0.00 1). The O-R brush was statistically significantly more effective in reducing plaque and gingivitis than the sonic brush. Whole mouth, gingival margin, and approximal plaque reductions were 27.7%, 46.8%, and 29.3% greater, respectively, compared with the sonic brush, while the reductions in gingivitis, gingival bleeding, and number of bleeding sites were 34.6%, 36.4%, and 36.1% greater, respectively, for the O-R brush than for the sonic brush (p < 0.001 for all six measures). No adverse events were observed for either brush., Conclusion: The plaque and gingivitis reductions for the O-R power brush incorporating the angled-bristled brush head were significantly greater than for the sonic power brush.

Purpose: To evaluate the efficacy of brushing and flossing order on control of plaque and gingival inflammation., Materials and Methods: This cross-over clinical trial was conducted on 35 students recruited from the dental school at Hamadan University of Medical Sciences. The subjects were asked to use dental floss and then brush for a 2-week period (FB), followed by brushing and then using dental floss for another 2-week period (BF). For a 7-day washout interval between the two phases, the subjects practiced dental hygiene according to their habitual method. The participants received dental prophylaxis at the beginning and plaque control record (PCR), plaque index (PI) and bleeding point index (BPI) were measured at baseline and the end of both phases. The differences of indices between two phases were analysed with the Wilcoxon signed rank test; to assess the influence of sex and sequence on PCR, PI and BPI, analysis of covariance (ANCOVA) was used after adjustment of initial values., Results: The PCR and PI indices in the FB method were significantly lower than with the BF method (P < 0.05). The PI and PCR index differences between the two phases were significant in men but nonsignificant in women. The effect of gender on PI and BPI and the interaction effect of sex and sequence of brushing and flossing on BPI were significant (P < 0.05)., Conclusions: Flossing followed by brushing provides more statistically significant improvements over brushing followed by flossing with respect to plaque control.

Patients with generalized periodontitis studied the effect of the partial removable denture made from acrylic met and thermoplastic materials on the state of periodontal tissues. The results of clin- ical studies have shown a significant improvement in oral hygiene, positive change in activity indi- cators current generalized periodontitis: patients for whom orthopedic constructions are made of thermoplastic mass, reduce the depth of periodontl pockets, tooth mobility, bleeding and inflamma- tion of the interdental, papillae and the gingival margin.

Purpose: The present study was conducted to assess the effectiveness of Terminalia chebula on plaque and gingival inflammation and compare it with the gold standard chlorhexidine (CHX 0.2%) and distilled water as control (placebo)., Materials and Methods: A double-blind randomised control trial was conducted among undergraduate students who volunteered. They were randomly allocated into three study groups: 1) Terminalia chebula mouthwash (n = 30); 2) chlorhexidine (active control) (n = 30); 3) distilled water (placebo) (n = 30). Assessment was carried out according to plaque score and gingival score. Statistical analysis was carried out to compare the effect of both mouthwashes. ANOVA and post-hoc LSD tests were performed using SPSS version 17 with p ≤ 0.05 considered statistically significant., Results: Our result showed that Terminalia chebula mouthrinse is as effective as chlorhexidine in reducing dental plaque and gingival inflammation. The results demonstrated a significant reduction of gingival bleeding and plaque indices in both groups over a period of 15 and 30 days as compared to the placebo., Conclusion: The results of the present study indicate that Terminalia chebula may prove to be an effective mouthwash. Terminalia chebula extract mouthrinse can be used as an alternative to chlorhexidine mouthrinse as it has similar properties without the side-effects of the latter.

Objectives: To determine the effectiveness of a novel sonic toothbrush in reducing plaque and in maintenance of gingival health when compared to a standard manual brush., Methods: This study was a block-randomized, examiner-blind, two-treatment, parallel group, single centre clinical investigation. A total of 84 subjects were enrolled and randomly assigned to receive either the Panasonic EW-DL90 or an American Dental Association-endorsed manual toothbrush. Subjects were instructed to follow a twice-daily brushing regimen without flossing. Plaque levels and gingival health were assessed at baseline and after 1 and 3 weeks of treatment using the Turesky Modification of the Quigley-Hein Plaque Index and the Papillary Bleeding Score., Results: Subjects assigned to the EW-DL90 group had significantly lower plaque levels after 1 and 3 weeks of treatment than those in the manual group (P = 0.003 and 0.0035, respectively). Both groups showed a reduction in plaque levels at Week 3 relative to baseline. The EW-DL90 group had significantly lower gingival inflammation scores after 1 week of treatment (P = 0.0293), but there was no difference between groups after 3 weeks of treatment., Conclusion: The EW-DL90 toothbrush safely and effectively removes more plaque than a standard manual toothbrush. Improvement in gingival inflammation was observed after 1 week of treatment. There was no difference in Papillary Bleeding Score between the two groups after 3 weeks of treatment., Clinical Significance: The newly developed sonic brush (Panasonic EW-DL90) tested in this study was found to be more effective than a manual toothbrush at plaque removal. The papillary bleeding scores were significantly lower in the sonic brush group after 1 week of product use. After 3 weeks of product use, both treatment groups had similar papillary bleeding scores almost returning to baseline values., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Objectives: To evaluate repeated subgingival air-polishing in residual pockets with a new erythritol powder containing 0.3% chlorhexidine., Material and Methods: Single-centre, examiner masked, randomized clinical trial of 12 months with a two-arm, within-subject parallel design. Fifty patients in periodontal maintenance were monitored in 3-month intervals. At months 0, 3, 6 and 9, all sites presenting with a probing depth (PD) >4 mm were subject to subgingival air-polishing (test side) or ultrasonic debridement (control side). The primary endpoint was presence/absence of PD >4 mm after 12 months., Results: Totally 6918 sites were monitored at baseline, 457 of them had a PD >4 mm (range 5-9 mm). The number of pockets >4 mm per subject, PD and bleeding on probing were significantly lower at month 12. Differences between test and control were not significant. There was a significant difference in favour of air-polishing for the perception of pain/discomfort. Differences of frequencies at >1000 and >100,000 cells/ml of six microorganisms between baseline and month 12 were not significant. At month 12, test sites were less frequently positive for Aggregatibacter actinomycetemcomitans at >1000 cells/ml than controls, and counts never exceeded 100,000 cells/ml., Conclusions: Repeated subgingival air-polishing reduced the number of pockets >4 mm similar to ultrasonic debridement. It was safe and induced less pain., (© 2014 The Authors. Journal of Clinical Periodontology Published by John Wiley & Sons Ltd.)

Objective: This 1-month longitudinal study assessed whether the oral status and the oral-health-related quality of life (OHRQoL) of children changed after four sessions of an educational preventive programme., Study Population and Methods: Fifty Brazilian students (11-12 year old) were examined for signs and symptoms of gingivitis using the Community Periodontal Index and two questions about gingival bleeding. The OHRQoL was measured using the Brazilian Portuguese version of the Child Oral Impacts on Daily Performances (Child-OIDP). Higher scores indicated worse OHRQoL. The results were analysed using the Shapiro-Wilk, Chi-square, Wilcoxon signed-rank and Mann-Whitney tests. The magnitude of the mean change was calculated using the effect size., Results: Twenty-four percentage of children had more than six sites with bleeding at follow-up compared with 58% at baseline. There was a significant decline in the intensity and extension of impacts at follow-up. A significant improvement in the clinical status and oral hygiene was observed for both transitional categories. There was a significant decline in the Child-OIDP scores of those reporting 'much improved'. A significant improvement in the global ratings of oral health was observed at follow-up., Conclusions: In the studied sample, an improvement occurred with respect to the severity of disease, intensity and extension of impacts and global ratings of oral health after 1-month follow-up. These results suggest that improving the global transition in health by enhancing coping and management skills while inducing slight changes in the clinical status and the specific aspects of health compromised by the disease is possible., (© 2014 John Wiley & Sons A/S.

Purpose: This randomized, single center, examiner-blind, controlled, parallel-group, 6-month clinical study compared the antiplaque/antigingivitis potential of an essential oil (EO) versus a 0.07% cetylpyridinium chloride (CPC)-containing mouthrinse. A 5% hydroalcohol solution was included as a control group., Methods: 354 healthy volunteers (18-71 years of age) were enrolled in this clinical trial; 338 subjects completed the study. At baseline, 1-, 3-, and 6-month visits, subjects received an oral examination, gingivitis (MGI), gingival bleeding (BI) and plaque assessments (PI). Following randomization, subjects received a prophylaxis and began brushing twice daily with the provided fluoride toothpaste and rinsing twice daily with 20 mL of the assigned mouthrinse for 30 seconds., Results: All rinses were well tolerated by the subjects, with the exception of extrinsic tooth stain complaints in 13 subjects in the CPC group between the 3- and 6-month exams. Statistically significant reductions in gingivitis, bleeding and plaque were observed for both EO and CPC at all post-baseline time-points when compared to the negative control. At 6 months MGI and PI were reduced by 42.6% and 42.0% for EO and by 17.1% and 13.9% respectively, for CPC vs. control. When compared to CPC, EO was statistically significantly superior at all post-baseline time-points. EO showed increasing reductions in MGI of 10.5%, 20.3% and 30.7% as well as reductions in PI of 12.7%, 23.7% and 32.6% at 1, 3 and 6 months, respectively. When analyzing the number of healthy sites (MGI scores of 0 or 1), the beneficial effect of the EO-containing mouthrinse is 45.8% greater than using a CPC-containing mouthrinse and 59.8% greater than placebo.

Purpose: To assess the anti-plaque and anti-gingivitis effects of a dentifrice containing 0.3% triclosan, 2% copolymer and 0.243% (1,100 ppm) sodium fluoride in subjects with moderate plaque-induced gingivitis., Methods: This was a single center, monadic study. Subjects had at least 20 teeth remaining in the functional dentition, excluding third molars. Following a baseline examination for plaque, gingival inflammation and bleeding, 75 qualified healthy adult males and females, ages 18-70 were selected to participate in the study. Dental prophylaxis was performed and subjects were provided with two tubes of toothpaste (Colgate Total) and a soft-bristle toothbrush (Colgate Wave Toothbrush). The subjects were instructed to brush twice daily using a modified Bass brushing technique. At the end of the 6- to 8-week period subjects returned for collection of clinical and subjective data., Results: 75 subjects completed the study. Both clinical and subjective reductions were significant. The results showed statistically significant reductions in plaque index, gingival inflammation and bleeding on probing. The overall conclusion was that Colgate Total was a comprehensive dentifrice that produced a significant reduction in gingivitis, plaque, and bleeding.

Medicinal plants represent important therapeutic resources to health restoration, including the use of herbal products in the mouth conditions treatment. A randomized controlled clinical trial was performed in order to evaluate the effectiveness of mouth rinse with pomegranate and chamomile plant extracts, against chlorhexidine 0.12% in the gingiva bleeding condition. The mouth rinses with the herbal products were effective for this case, showing thus, antimicrobial and anti-inflammatory properties similar to that of chlorhexidine 0.12%., (Copyright © 2013 Elsevier Ltd.

Objective: To evaluate the efficacy of a marketed oscillating-rotating (O-R) power toothbrush (Oral-B Triumph with SmartGuide and FlossAction brush head, D34/EB25) to a new sonic toothbrush (Sonicare FlexCare Platinum) in the reduction of gingivitis and plaque over a 12-week test period., Methods: This was a single center, randomized, open label, examiner-blind, two-treatment, parallel group study. Subjects who met the entrance criteria were enrolled in the study and randomly assigned to either the O-R or sonic treatment group. Subjects brushed with their assigned toothbrush and a marketed fluoride dentifrice for two minutes twice daily at home for 12 weeks. Gingivitis and plaque were evaluated at Baseline, Week 6, and Week 12. Gingivitis was assessed using the Modified Gingival Index (MGI) and Gingival Bleeding Index (GBI), and plaque was assessed using the Rustogi Modified Navy Plaque Index (RMNPI). Data were analyzed using an Analysis of Covariance (ANCOVA) with Baseline as the covariate., Results: In total, 130 subjects (65 per group) were randomized to treatment and 127 subjects completed the study. Both brushes produced statistically significant (p < 0.001) reductions in gingivitis and plaque measures relative to Baseline. At Week 12, the O-R brush demonstrated significantly greater reductions than the sonic brush in whole mouth gingivitis measures (p = 0.007). Additionally, the O-R brush presented significantly fewer bleeding sites (p < 0.007) and significantly greater reductions in whole mouth plaque measures (p < or = 0.035) at Weeks 6 and 12 versus the sonic brush. The benefit for the O-R brush versus the sonic brush at Week 12 was 11.7% for gingivitis, 19.8% for number of bleeding sites, and 12.2% for whole mouth plaque. There were no adverse events reported or observed for either brush., Conclusion: The oscillating-rotating toothbrush demonstrated statistically significantly greater reductions in whole mouth plaque at Weeks 6 and 12, as well as significantly greater gingivitis reductions over the long-term (12 weeks), compared to the new sonic toothbrush.

Aim: To assess the efficacy of a 0.07% cetylpyridinium chloride (CPC) mouth rinse in the control of plaque and gingival inflammation during a 6-month period., Material and Methods: Adult subjects with moderate gingivitis were selected [≥40% bleeding on marginal probing (BOMP)]. After retrieving microbiological samples and evaluating the clinical parameters (plaque, BOMP and stain indexes), a professional prophylaxis was performed and subjects were randomly assigned to the test (CPC mouth rinse) or to the placebo group. Subjects were re-assessed after 3 and 6 months., Results: A total of 67 patients (35 test, 32 placebo) were included in the analysis. At 6 months, intra-group significant plaque reductions were observed in the test group (0.691, p < 0.001), but not in the placebo (0.181, p = 0.653). At 6 months, the mean BOMP values were lower in the test group (p = 0.052). Changes between baseline and 6 months were significantly higher in the test group both for plaque (p = 0.002) and BOMP (p = 0.037) when compared with the placebo. A microbiological impact was observed in the test group, especially for Prevotella intermedia., Conclusion: The evaluated 0.07% CPC-based mouth rinse, used three times per day adjunctively to mechanical tooth cleaning, prevents plaque accumulation and gingival inflammation, as compared to the placebo, for at least 6 months., (© 2013 John Wiley & Sons A/S.

Background: Simplified periodontal therapy might be a pragmatic strategy for public health programmes targeting Indigenous Australian adults. The objective of this randomized controlled trial was to evaluate oral health effects of single-visit, non-surgical periodontal therapy compared to no treatment., Methods: This parallel-group, randomized, open label clinical trial enrolled 273 Indigenous Australians aged ≥18 years with periodontitis. Intervention participants received full-mouth periodontal scaling and root planing during a single visit while the control group received no treatment. Endpoints were summary variables derived from clinical assessments of probing depth, clinical attachment loss, plaque, calculus and gingival bleeding before treatment and 3 months later., Results: Endpoints could be calculated for 169 participants with follow-up data. Compared to the control group, there were statistically significant reductions in extent of shallow pockets: PD ≥4 mm (mean difference -2.86, [95% CI -5.01 to -0.71], p = 0.009) and gingival bleeding (mean difference -0.25, [95% CI -0.43 to -0.08], p = 0.005) but not deeper pockets PD ≥5 mm (mean difference -0.48, [95% CI -1.78 to 0.82], p = 0.468) or plaque scores., Conclusions: Periodontal therapy produced improvements in shallow periodontal pockets and measures of gingival bleeding in these Indigenous Australians., (© 2013 John Wiley & Sons A/S.

Aim: The aim of the present study was to highlight the relationship between the level of oral hygiene and the context in which the patient receives dental treatment, demonstrating that home service is essential and effective to decrease the incidence of periodontal diseases., Methods: The study was initially conducted on a heterogeneous sample of patients including 48 individuals with psycho-motor deficits. The study included 28 males (58.3%) and 20 females (41.7%) aged between 18 and 50 years, coming from two different sites ("Fa.Di.Vi… e oltre" and "Dentistry Unit, Istituto G. Gaslini" in Genoa). The patients were evaluated during the period 2008-2009. After this first pilot study, a clinical trial was conducted within the educational center "Il Granello", with the participation of 20 patients with disabilities., Results: This study demonstrates that home assistance is essential and effective to decrease the incidence of those periodontal diseases induced by bacterial dental plaque accumulation, and associated with aggravating factors like the repeated use of drugs, such as benzodiazepines, phenylhydantoin, and cyclosporin A, that cause gingival hypertrophia., Conclusion: This study was proposed to demonstrate that the availability of a dental service within institutions could improve not only the dental-periodontal conditions of the participants, but also decrease the admission of these subjects to hospitals, contributing to the reduction of public expenditure by the Health Care System.

Purpose: This double-blind randomized controlled trial assessed the effect of subgingival ozone (O3, gaseous ozone, HealOzone MK II, KaVo) and/or hydrogen peroxide (H2O2) on the development of peri-implant mucositis., Materials and Methods: Twenty subjects (mean age, 60 ± 7.7 years) with 80 implants (4 implants each) were recruited. First, a 2-week pretrial phase took place to achieve healthy gingiva. Subsequently, partial gum shields were constructed for the experimental area (around the 4 implants); subjects were asked to refrain from brushing in that area by wearing the gum shield. The following treatments were randomly applied (for 60 seconds) to implant sites on days 0, 7, and 14: (1) air (O2) and saline (0.9% NaCl) (control group), (2) O2 and H2O2 (3%), (3) O3 and saline, and (4) O3 and H2O2. Plaque, gingival, and bleeding indices were recorded on days 0, 7, 14, and 21., Results: Significant differences were seen among the treatments (P < .01) in plaque (F = 16.68), modified gingival (F = 7.86), and bleeding (F = 18.42) indices. O3 + saline and O3 + H2O2 produced optimum gingival health scores and were equally effective and the most effective in controlling bleeding (mean score = 0.05), while O2 + saline was the least effective (mean score = 0.56)., Conclusion: Ozone showed great potential for management of peri-implant mucositis.

Background: Periodontal disease is the most common oral disease affecting adults, and although it is largely preventable it remains the major cause of poor oral health worldwide. Accumulation of microbial dental plaque is the primary aetiological factor for both periodontal disease and caries. Effective self-care (tooth brushing and interdental aids) for plaque control and removal of risk factors such as calculus, which can only be removed by periodontal instrumentation (PI), are considered necessary to prevent and treat periodontal disease thereby maintaining periodontal health. Despite evidence of an association between sustained, good oral hygiene and a low incidence of periodontal disease and caries in adults there is a lack of strong and reliable evidence to inform clinicians of the relative effectiveness (if any) of different types of Oral Hygiene Advice (OHA). The evidence to inform clinicians of the effectiveness and optimal frequency of PI is also mixed. There is therefore an urgent need to assess the relative effectiveness of OHA and PI in a robust, sufficiently powered randomised controlled trial (RCT) in primary dental care., Methods/design: This is a 5 year multi-centre, randomised, open trial with blinded outcome evaluation based in dental primary care in Scotland and the North East of England. Practitioners will recruit 1860 adult patients, with periodontal health, gingivitis or moderate periodontitis (Basic Periodontal Examination Score 0-3). Dental practices will be cluster randomised to provide routine OHA or Personalised OHA. To test the effects of PI each individual patient participant will be randomised to one of three groups: no PI, 6 monthly PI (current practice), or 12 monthly PI.Baseline measures and outcome data (during a three year follow-up) will be assessed through clinical examination, patient questionnaires and NHS databases.The primary outcome measures at 3 year follow up are gingival inflammation/bleeding on probing at the gingival margin; oral hygiene self-efficacy and net benefits., Discussion: IQuaD will provide evidence for the most clinically-effective and cost-effective approach to managing periodontal disease in dentate adults in Primary Care. This will support general dental practitioners and patients in treatment decision making., Trial Registration: Protocol ID: ISRCTN56465715.

Purpose: To evaluate the anti-gingivitis benefits of a 0.454% highly bioavailable stannous fluoride dentifrice (SnF2) relative to a 0.3% triclosan/copolymer dentifrice (triclosan/copolymer) among triclosan/copolymer dentifrice users with residual gingivitis., Methods: This was a randomized, controlled, double-blind, parallel group, 2-month clinical study. Self-reported triclosan/copolymer dentifrice users were recruited and provided with triclosan/copolymer dentifrice to use for 1 month. After this 1-month acclimation period, subjects who had residual gingivitis at the baseline visit were randomized to either the SnF2 dentifrice or the triclosan/copolymer dentifrice (positive control). Subjects performed their treatment unsupervised using their assigned dentifrice following manufacturers' usage instructions for 2 months. The Gingival Bleeding Index (GBI) and Modified Gingival Index (MGI) were used to measure gingivitis benefits at baseline and Month 2. An analysis of covariance was performed to compare treatment groups for the post-baseline scores as well as change from baseline, with the baseline score as a covariate. All comparisons were two-sided at the 0.05 level of significance., Results: A total of 150 subjects were randomized to treatment. Both treatment groups experienced significant reductions in number of bleeding sites, gingival bleeding index (GBI), and gingival inflammation (MGI) relative to baseline (P < 0.001). At Month 2, the SnF2 dentifrice group demonstrated significantly lower adjusted mean scores versus the triclosan/copolymer group for number of bleeding sites, GBI, and MGI (P < 0.001). Between-treatment group comparisons for change from baseline values showed that the improvement in number of bleeding sites from baseline for the SnF2 group was 49% greater versus that of the triclosan/copolymer group (P < 0.001), and the GBI and MGI improvements from baseline for the SnF2 group were 48% and 37%, greater, respectively, relative to the triclosan/copolymer group (P < 0.001).

Background: Oral hygiene and health of the institutionalized elderly are frequently described as inadequate., Objectives: This randomized and single-blinded (outcome evaluation) study compared three types of intervention for improving oral hygiene with a control. The purpose was to investigate whether there were any significant differences between the intervention and control groups., Methods: One hundred and six participants living in long-term care homes in South-West Germany were recruited and randomly divided into four groups-three therapy groups and one control group. For all three therapy groups, teeth and dentures were cleaned professionally and individual instruction was given. One of these groups was also re-instructed and remotivated by a dentist (n = 27). One also received help from, and was remotivation by, staff educated in dental hygiene (n = 26). The third therapy group was not remotivated after professional cleaning of teeth and dentures (n = 26). For the control group, there was no intervention (n = 23). The main target clinical data were mean plaque (plaque-control record, O'Leary), gingival bleeding (Ainamo/Bay), and denture hygiene indices. For assessment of the difference between being in an intervention group and in a control group, mixed-model analysis for repeated measurements was performed for each main target variable. In addition, target clinical data were evaluated in long-term follow-up after 3 years., Results: Compared with controls, denture hygiene, plaque, and gingival bleeding indices were significantly lower in the intervention groups over a twelve-week period (mixed model for repeated measurements; P < 0.023). Estimates of effects between control and each treatment group were comparable among the three therapy groups; however, even though two of the groups received further help and instruction. Long-term follow-up showed that all indices were significantly worse than at the last study recall (P < 0.001)., Conclusions: Professional cleaning of teeth and dentures, with individual instruction, can be recommended to improve oral hygiene. However, the effect decreases over time and renewal of the intervention is necessary., (© 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Peri-implantitis is one of many reasons for dental implant failure. This study is designed to prevent experimental peri-implantitis by arginine-specific gingipain A (rgpA) DNA vaccine., Methods: The bilateral mandibular second and third premolars from 15 male beagle dogs were extracted, and 60 implants were immediately implanted. Three months after implantation, the animals were randomly divided into groups A, B, and C and immunized with plasmid vector-rgpA, heat-killed Porphyromonas gingivalis, and plasmid vector, respectively. Cotton ligatures infiltrated with P. gingivalis were placed in the submarginal position around the neck of the implants to induce peri-implantitis. Clinical measurements, including probing depth (PD) and bleeding on probing, were recorded every 2 weeks postoperatively, and P. gingivalis-specific immunoglobulin G (IgG) in serum and secretory IgA (sIgA) in saliva were quantitatively analyzed by enzyme-linked immunosorbent assay at the same time. Animals were sacrificed after 6 weeks, 50-μm undecalcified histologic sections were prepared using methylene blue dye, and bone loss around implants was measured., Results: Higher levels of IgG in serum and sIgA in saliva could be measured in groups A and B but not in group C after immunization. There were statistical differences (P <0.05) between, before, and after immunization, but no difference was found between groups A and B (P >0.05). Both peri-implant PD and bone loss in group A were significantly less than in groups B and C., Conclusions: IgG and sIgA could be generated by immunization with rgpA DNA vaccine, which could significantly slow down bone loss in the experimental peri-implantitis canine model.

Dental care among young adults with intellectual disability (ID) is poorly documented and largely unmet. By using population-based data from the Metropolitan Atlanta Developmental Disabilities Follow-Up Study, we assessed factors associated with at least one or two dental visits per year among young adults with and without ID. Significantly fewer young adults with ID (45%) visited a dentist at least once per year, compared with those without ID (58%). ID severity and the presence of co-occurring developmental disabilities predicted dental care use. Sociodemographics, daily functioning, societal participation, dental services, and dental health factors were examined as predictors of dental care frequency. Our findings can help focus efforts toward improving the frequency of dental care visits among young adults with ID., (Published by Elsevier Ltd.)

Aim: To evaluate the efficacy of triclosan (T)-based toothpaste formulations in the prevention and treatment of plaque-induced periodontal and peri-implant diseases., Methods: A review of the existing literature was conducted with a systematic approach in order to retrieve pertinent articles., Results and Conclusions: i) Compared with a control fluoride dentifrice, a fluoride dentifrice containing T formulations provides a more effective level of plaque control and gingival health in patients affected by gingivitis; ii) 0.3% T/2% copolymer/0.243% NaF formulation and 0.3% T/0.13% Ca glicerophosphate/1000 ppm F toothpaste in a natural Ca carbonate base seem the most effective T-based toothpaste formulations in controlling plaque and gingival inflammation in patients with gingivitis or mild/moderate periodontitis over a 6-month period; iii) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation can reduce clinical attachment loss in young adolescents when compared with a 0.243% NaF toothpaste formulation, the magnitude of the difference being greater for patients with deep periodontal pockets at baseline; iv) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation is either similarly or more efficacious in preventing the progression/recurrence of periodontal destruction when compared to a conventional fluoride toothpaste; v) 0.3% T/2% copolymer/0.243% NaF toothpaste formulation seems to be more effective than a fluoride toothpaste formulation in controlling the severity of mucosal inflammation, the incidence of mucosal bleeding as well as reducing probing pocket depth around dental implants.
