Aim The aim of this systematic review was to evaluate the efficacy of anti-plaque chemical formulations for managing gingivitis, in 6-month, home-use, randomised clinical trials ( RCTs). Material and Methods A protocol was designed, including inclusion and exclusion criteria to identify RCTs assessing gingival and/or bleeding indices. Electronic and hand-searches identified relevant papers, which were screened and evaluated for inclusion. Full-papers were retrieved and relevant information was extracted (also plaque indices), including quality and risk of bias. Mean treatment effects were calculated to obtain weighted mean differences ( WMD) and 95% confidence intervals. Results After the process of screening and selection, 87 articles with 133 comparisons, were included in the review. The additional effects of the tested products were statistically significant in terms of Löe & Silness gingival index (46 comparisons, WMD −0.217), modified gingival index ( n = 23, −0.415), gingivitis severity index ( n = 26, −14.939%) or bleeding index ( n = 23, −7.626%), with significant heterogeneity. For plaque, additional effects were found for Turesky (66 studies, WMD −0.475), Silness & Löe ( n = 26, −0.109), and plaque severity ( n = 12, −23.4%) indices, with significant heterogeneity. Conclusion Within the limitations of the present study, formulations with specific agents for chemical plaque control provide statistically significant improvements in terms of gingival, bleeding and plaque indices.

Objective: To assess methods, quality and outcomes of systematic reviews (SRs) conducted to evaluate the effectiveness of root coverage (RC) procedures in the treatment of recession-type defects (RTD). Methods: MEDLINE and EMBASE were searched up to and including April 2010 to identify SRs investigating the effectiveness/efficacy of surgical interventions for the treatment of patients with RTD. Searching was conducted independently by two reviewers, and data extraction was based on the methodological criteria applied and on the effects of interventions reported by each SR. The checklist proposed by Glenny and colleagues, the Overview Quality Assessment Questionnaire and the "Assessment of Multiple systematic Reviews", instrument were used to assess the quality of SRs. Additionally, the methodological criteria applied by included reviews were compared with those proposed by the Cochrane Collaboration. Results: Search strategy identified 716 potentially eligible articles, of which 12 papers regarding 10 SRs were included in the study. Results from different SRs showed that subepithelial connective tissue grafts associated or not to coronally advanced flaps can be used to reduce recession depth and improve the width of keratinized tissue. All quality assessment tools showed that most of the SRs were of good methodological quality, but they also highlighted key points that could be improved in future reviews. Only two SRs followed in full the guidelines proposed by the Cochrane Collaboration. Conclusions: All SRs agree that RC may be anticipated by different surgical procedures. However, differences in the methodological quality between reviews were quite evident, and thus making a clear indication that there is a need of standardization of the methods that will be applied by future SRs. As a result, a standardized checklist for reporting SRs was proposed by the authors. [ABSTRACT FROM AUTHOR]

Aim To report the evidence on the effect of mechanical and/or chemical plaque control in the simultaneous management of gingivitis and caries. Material and Methods A protocol was designed to identify randomized ( RCTs) and controlled ( CCTs) clinical trials, cohort studies and prospective case series ( PCS), with at least 6 months of follow-up, reporting on plaque, gingivitis and caries. Relevant information was extracted from full papers, including quality and risk of bias. Meta-analyses were performed whenever possible. Results After the screening of 1,373 titles, 15 RCTs, 10 CCTs and 2 PCS were included. Low to moderate evidence support that combined professional and self-performed mechanical plaque control significantly reduces standardized plaque index [ n = 4; weighted mean difference ( WMD) = 1.294; 95% CI (0.445; 2.144); p = 0.003] and gingivitis scores [ n = 4; WMD = 1.728; 95% CI (0.631; 2.825); p = 0.002]. The addition of fluoride to mechanical plaque control is relevant for caries management [ n = 5; WMD = 1.159; 95% CI (0.145; 2.172); p = 0.025] while chlorhexidine rinses are relevant for gingivitis. Conclusion Mechanical plaque control procedures are effective in reducing plaque and gingivitis. The addition of fluoride to mechanical plaque control is significant for caries management. Chlorhexidine rinse has a positive effect on gingivitis and inconclusive role in caries. [ABSTRACT FROM AUTHOR]

Objective This randomized clinical trial aimed at comparing radiological, clinical and microbial effects of surgical treatment of peri-implantitis alone or in combination with enamel matrix derivative ( EMD). Methods Twenty-six subjects were treated with open flap debridement and decontamination of the implant surfaces with gauze and saline preceding adjunctive EMD or no EMD. Bone level ( BL) change was primary outcome and secondary outcomes were changes in pocket depth ( PD), plaque, pus, bleeding and the microbiota of the peri-implant biofilm analyzed by the Human Oral Microbe Identification Microarray over a time period of 12 months. Results In multivariate modelling, increased marginal BL at implant site was significantly associated with EMD, the number of osseous walls in the peri-implant bone defect and a Gram+/aerobic microbial flora, whereas reduced BL was associated with a Gram−/anaerobic microbial flora and presence of bleeding and pus, with a cross-validated predictive capacity ( Q2) of 36.4%. Similar, but statistically non-significant, trends were seen for BL, PD, plaque, pus and bleeding in univariate analysis. Conclusion Adjunctive EMD to surgical treatment of peri-implantitis was associated with prevalence of Gram+/aerobic bacteria during the follow-up period and increased marginal BL 12 months after treatment.

Background The aim of this study was to assess the clinical efficacy of coronally advanced flap ( CAF) with or without connective tissue graft ( CTG) for the treatment of multiple adjacent gingival recessions in the upper arch. Material and Methods Thirty-two patients with a total of 74 gingival recessions were randomly allocated to the two groups. Outcome measures, collected by a blind examiner, included complete root coverage ( CRC), recession reduction (RecRed), keratinized tissue ( KT) gain, increase in gingival thickness (GT), patient satisfaction and root coverage esthetic score ( RES). Results An interaction between treatment and baseline GT was detected. At 1 year, CAF + CTG resulted in better outcomes in terms of CRC ( p = 0.0016) and RecRed ( p < 0.0001) than CAF alone at sites with thin gingiva (thickness ≤ 0.8 mm). No difference was found between CAF alone and CAF + CTG at sites with thick gingiva (>0.8 mm). CAF resulted in higher aesthetic scores ( RES) than CAF + CTG at sites with thick gingiva. CAF + CTG was associated with greater KT gain ( p < 0.0001) and greater post-operative morbidity ( p < 0.0001). Conclusion Connective tissue graft under CAF results in increased probability of CRC only at sites with thin baseline gingiva. CAF alone is associated with similar clinical outcomes and better aesthetics at sites with thick baseline gingiva. [ABSTRACT FROM AUTHOR]

Focused Question: In patients suffering from peri-implant diseases, what is the efficacy of air polishing on changing signs of inflammation compared with control treatments (i.e. alternative measures for plaque removal with or without adjunctive antiseptic and/ or antibiotic therapy)? Material & Methods: After electronic database and hand search, 10 full-text articles were independently screened by two reviewers. Finally, a total of five studies (six publications) fulfilled the inclusion criteria. The weighted mean difference (WMD) [p; 95% CI] in bleeding on probing-(BOP) (primary outcome) and probing pocket depth-(PD) reductions was estimated using a random effect model. Results: All studies reported on residual BOP scores after therapy. A narrative data synthesis did not reveal any major improvement of bleeding index/ BOP or disease resolution following air polishing over mechanical debridement at mucositis sites. At peri-implantitis sites, WMD in BOP reduction between test and control (mechanical debridement with or without local antiseptic therapy, Er:YAG laser) groups was -23.83% [p = 0.048; 95% CI (-47.47, -0.20)] favouring air polishing over control measures. Conclusions: While glycine powder air polishing is as effective as the control treatments at mucositis sites, it may improve the efficacy of non-surgical treatment of peri-implantitis over the control measures investigated. A complete disease resolution was commonly not obtained. [ABSTRACT FROM AUTHOR]

Aim The aim is to assess the effect of desensitizing toothpaste on dentin hypersensitivity. Methods We searched PubMed, CENTRAL, and Embase on December 20, 2013. Results Out of the 626 articles searched, a total of 31 randomized controlled clinical trials were included. The Standardized mean differences ( SMD) for potassium-containing toothpaste ( n = 8) was −1.28 (95% Confidence interval ( CI) −2.05 to −0.51; I2 = 93%); Stannous fluoride- ( n = 6) was −1.37 (95% CI, −2.30 to −0.44; I2 = 95%); Potassium and stannous fluoride- ( n = 3) was −2.50 (95% CI, −4.10 to −0.91; I2 = 95%); Calcium sodium phosphosilicate - ( n = 4) was −2.36 (95% CI, −3.72 to −1.00; I2 = 92%); Arginine- ( n = 8) was −3.25 (95% CI, −3.87 to −2.63; I2 = 86%). The desensitizing effect was favoured in the intervention group treated with potassium-, stannous fluoride-, potassium and stannous fluoride-, calcium sodium phosphosilicate-, and arginine-containing toothpaste compared to placebo. Whereas, strontium-containing toothpaste ( SMD, 0.05; 95% CI, −0.34 to 0.44; I2 = 64%) was found to have no statistically significant desensitizing effect in the meta-analysis of four studies. Conclusions The study reports that there is sufficient evidence to support the use of potassium-, stannous fluoride-, potassium and stannous fluoride-, calcium sodium phosphosilicate-, and arginine-containing desensitizing toothpastes for dentin hypersensitivity, but not the use of strontium-containing desensitizing toothpaste.

Objective The purpose of this ongoing randomized study was to assess differences in bone level changes and success rates using implants supporting single crowns in the posterior mandible either with platform matched or platform switched abutments. Material and Methods Patients aged 18 and above, missing at least two teeth in the posterior mandible and with a natural tooth mesial to the most proximal implant site were enrolled. Randomization followed implant placement. Definitive restorations were placed after a minimum transgingival healing period of 8 weeks. Changes in crestal bone level from surgery and loading (baseline) to 12-month post-loading were radiographically measured. Implant survival and success were determined. Results Sixty-eight patients received 74 implants in the platform switching group and 72 in the other one. The difference of mean marginal bone level change from surgery to 12 months was significant between groups ( p < 0.004). Radiographical mean bone gain or no bone loss from loading was noted for 67.1% of the platform switching and 49.2% of the platform matching implants. Implant success rates were 97.3% and 100%, respectively. Conclusions Within the same implant system the platform switching concept showed a positive effect on marginal bone levels when compared with restorations with platform matching.

Background This RCT compared non-surgical treatment of peri-implant mucositis with or without systemic antibiotics. Materials and Methods Forty-eight subjects received non-surgical debridement with or without systemic Azithromax ® (4 days), and were followed during 6 months. The checkerboard DNA- DNA hybridization method was used to analyse the microbiological material. Results Five subjects were excluded due to antibiotic medication during follow-up. At baseline,1 and 3 months no group differences were found. Statistical analysis failed to demonstrate differences in probing pocket depths ( PPD) values at 6 months (Mean diff PPD: 0.5 mm, SE: ±0.4 mm, 95% CI: −0.2, 1.3, p = 0.16). Mean% implant bleeding decreased between baseline and month 6 from 82.6% to 27.3% in the test, and from 80.0% to 47.5% in the control group ( p < 0.02). Throughout the study, no study group differences in bacterial counts were found. Conclusion No short-term differences were found between study groups. The clinical improvements observed at 6 months may be attributed to improvements in oral hygiene. The present study does not provide evidence for the use of systemic antibiotics in treatment of peri-implant mucositis. [ABSTRACT FROM AUTHOR]
