Numerous studies have demonstrated that mouth rinsing with glucose enhance exercise; however, research on fructose is comparatively limited. Owing to unexpected taste preferences, fructose is rarely used in carbohydrate mouth rinsing studies. Therefore, the objective of this study is to compare perceived taste between glucose and fructose solutions. Ninety-six participants were assigned perform a set of mouth rinse trials with three different solutions in double blind-manner. Participants were instructed to rinse 25 mL of 6% glucose, 5.3% fructose, and 21.2% fructose for 10 seconds. Prior to using the second and third solutions for rinsing, participants were instructed to cleanse their mouth by rinsing with warm water. Following the warm water mouth rinse, participants were asked to assess the visual analog scale and taste test questionnaire before proceeding to rinse with the subsequent solution. The research revealed that the mean score of 21.2% for fructose was significantly higher (p < 0.05) in terms of preferred, sweetness and intensity compared to glucose at 6% and fructose at 5.3%. However, for taste, fructose 5.3% has greater mean than others. In general, fructose was predominantly favoured as preferred choice, likely due to its appealing sweetness and intensity. The findings recommend considering higher caloric intake of fructose during mouth rinsing to enhance brain activation and exercise performance, as fructose appears to be a more favoured option compared to glucose. This insight could guide future studies in this direction. [ABSTRACT FROM AUTHOR]

Introduction: Despite being a largely preventable disease, untreated caries of permanent teeth is estimated to affect almost 2 billion people worldwide, which is followed by severe periodontal disease. The aim of this work was to provide a professional consensus on tooth brushing methods and associated oral hygiene behaviours and develop evidence-informed recommendations. Methods: An initial scoping search was undertaken to identify systematic reviews of relevance and key questions. This was followed by comprehensive evidence mapping of the literature focussing on systematic reviews and clinical guidelines. Electronic searches of several databases including MEDLINE (via Ovid), Embase (via Ovid), Epistemonikos, and The Cochrane Library were undertaken from 2000 to May 2022, alongside a guideline repository search. Considered Judgement Forms were developed detailing the underpinning evidence, balance between benefits and harms, potential impact on the population, and feasibility of implementation. An online survey comprising 22 draft recommendations was distributed to international members of all FDI committees, including the FDI Council. Participants were asked to indicate to what level they agreed or disagreed with for each recommendation and to provide feedback. The Considered Judgement Forms were provided for reference. Results: Three hundred ten records were identified and mapped to different aspects of tooth brushing methods and associated behaviours. Research literature informed 7 Considered Judgement Forms comprising 12 questions with draft recommendations. Twenty-five participants from Asia, Europe, North and South America, Africa, and Australia provided feedback on the recommendations. More than 70% of respondents showed agreement with 21 of the 22 draft recommendations. Final recommendations were drafted with associated strength of recommendation. Conclusion: Using a robust methodology and an international professional consensus, a set of evidence-informed recommendations was developed. These recommendations provide clinicians with practical guidance to facilitate communications with patients that may help to reinforce individual-level preventive strategies.

Featured Application: The use of a cymenol-based mouth rinse is safe and well-tolerated by patients, with no reports of side effects or adverse events. The aim of this study was to evaluate a newly formulated mouth rinse containing cymenol in patients undergoing supportive periodontal care in terms of safety (primary outcome) and the impact on dental biofilm and gingival inflammation (secondary outcomes). This research was designed as a pilot, controlled, randomized, parallel, triple-blinded, single-center, clinical trial of a 12-week duration. Adverse events and product perception were assessed by a questionnaire. Clinical, patient-reported outcomes (PROs), compliance, tooth staining, dentin hypersensitivity and microbiological variables were also evaluated. Student T, Mann–Whitney-U and Chi-square tests were applied. Thirty participants (15 per group) were included, randomized and followed for 12 weeks. No adverse events were reported. The questionnaire showed an overall rating of 7.2 (out of 10) in the experimental group and of 8.2 in the control group (p = 0.165) at 12 weeks. No statistically significant differences were observed in terms of gingival health, tooth staining, dentin hypersensitivity or microbiological outcomes between groups at baseline, 6- and 12-week visits. The adjuvant use of the new mouth rinse formulation proved to be as safe as the control product and no significant differences were observed in terms of clinical efficacy. [ABSTRACT FROM AUTHOR]

This comprehensive review aimed (1) to characterize the sub- and supragingival microbiome in patients with biofilm-induced gingivitis (including experimental gingivitis), (2) to assess its stability and evolution over time, and (3) to assess the impact of biofilm control measures on this stability. An electronic search of the MEDLINE®/PubMed® database until December 2023 was conducted. NCBI Taxonomy, eHOMD 16S rRNA Reference Sequence, and Tree Version 15.23 databases were used to standardize taxonomic nomenclature. Out of 89 papers initially retrieved, 14 studies were finally included: 11 using experimental gingivitis as a model and three randomized clinical trials evaluating the impact of biofilm control measures. Among them, five characterized the subgingival microbiome, nine the supragingival microbiome, and one both the sub- and supragingival microbiome. In addition, five studies evaluated the effect of toothpaste, and four studies evaluated the effect of mouth rinses. The diversity and structure of the microbiome differed significantly between patients with periodontal health and those with biofilm-induced gingivitis (including experimental gingivitis). Those differences were not reversed through conventional oral hygiene measures. Specific antiseptic agents, especially if delivered as mouth rinses, may have an impact on the supra- and subgingival microbiome in gingivitis. [ABSTRACT FROM AUTHOR]

Background: Due to the COVID-19 pandemic, several associations worldwide have been recommending the use of 1% hydrogen peroxide solution as a preprocedural mouth rinse before dental treatments to reduce viral load in saliva. This protocol is also employed in stress studies, especially in the context of dental treatment that uses salivary biomarkers as an indicator. However, the effect of 1% hydrogen peroxide as mouth rinse on salivary biomarkers remains unclear. Objective: This study aims to investigate the effects of 1% hydrogen peroxide solution as a preprocedural mouth rinse on 3 salivary stress biomarkers—salivary cortisol, salivary secretory IgA, and salivary α-amylase—both on chemical influence and mechanical irrigation. Materials and methods: Ninety healthy participants with confirmed negative Reverse Transcription Polymerase Chain Reaction results for COVID-19 at most 2 days prior to the experiment were included in this study. All participants were randomly allocated into 3 groups: experimental (1% hydrogen peroxide solution), positive control (distilled water), and negative control (no mouth rinse). Saliva samples were collected before and after mouth rinsing with the respective solutions. Salivary biomarkers were analysed using specific enzyme-linked immunosorbent assay kits. Results: Salivary cortisol and salivary α-amylase did not significantly differ before and after rinsing, whilst salivary sIgA levels decreased in all 3 groups. Nonetheless, there were no significant differences in the changes of these biomarkers across the 3 groups. Conclusions: This study shows that using 1% hydrogen peroxide solution as a preprocedural mouth rinse for universal precaution does not alter the levels of these 3 salivary biomarkers.

Carbohydrate (CHO) mouth rinsing seems to improve performance in exercises lasting 30-60 min. However, its effects on intermittent exercise are unclear. It is also unknown whether serial CHO mouth rinses can promote additional ergogenic effects when compared with a single mouth rinse. The aim of this study was to evaluate the effect of single and serial CHO mouth rinses on Yo-Yo Intermittent Recovery Test Level 1 (Yo-Yo IR 1) performance in soccer players. In a randomized, crossover, double-blind, placebo-controlled design, 12 male ( 18.9 * 0.5 years) soccer players performed eight serial mouth rinses under three different conditions: placebo solution only (noncaloric juice), seven placebo mouth rinses plus a single CHO mouth rinse (8% maltodextrin), or eight CHO mouth rinses (8-CHO). Following the final mouth rinse, individuals performed the Yo-Yo IR 1 test to evaluate the maximal aerobic endurance performance measured via total distance covered. There were no differences in Yo-Yo IRl performance between sessions (p =.32; single CHO mouth rinse (8% maltodextrin): 1,198 + 289 m, eight CHO mouth rinses: 1,256 + 253 m, placebo: 1,086 * 284 m). In conclusion, single and serial CHO mouth rinsing did not improve performance during the Yo-Yo IRl for soccer players. These data suggest that CHO mouth rinsing is not an effective ergogenic strategy for intermittent exercise performance irrespective of the number of rinses. [ABSTRACT FROM AUTHOR]

Aim: This study aimed at investigating the efficacy of a 0.05% cetylpyridinium chloride–0.05% chlorhexidine (CPC–CHX) mouthwash in reducing viral load in the saliva as compared with sterile water. Materials and Methods: Forty SARS‐CoV‐2 positive patients were asked to dispense 4 mL of saliva. Half the patients rinsed for 60 s with 15 mL CPC–CHX, and the remaining patients rinsed with sterile water (control). Four millilitres of saliva were collected after 15, 30 and 60 min after rinsing. Quantitative reverse transcriptase polymerase chain reaction (RT‐qPCR) and enzyme‐linked immunosorbent assay (ELISA) specific for SARS‐CoV‐2 nucleocapsid protein were performed. For ELISA, the intact (representing the active virus) to total virus load (I/T) was calculated. Results: SARS‐CoV‐2 copy numbers/mL from RT‐qPCR tended to decrease in the control group, whereas in the CPC–CHX group, an increase was observed after T30. However, mixed linear model analysis revealed no statistical differences between groups (p =.124), time points (p =.616) and vaccinated or non‐vaccinated patients (p =.953). Similarly, no impact of group (p =.880), time points (p =.306) and vaccination (p =.711) was observed for I/T ratio values. Conclusions: Within the limitation of this study, there was no evidence that the intervention reduced salivary SARS‐CoV‐2 viral load during the course of 60 min. Therefore, commonly used pre‐procedural rinsing might not be clinically relevant. [ABSTRACT FROM AUTHOR]

Introduction: Previous randomized controlled trials have shown that the use of antiseptic mouth rinses not only eradicates oral bacteria but also disrupts their ability to convert nitrate to nitrite, which is the key molecule in regulating blood pressure (BP). Objective: This study aimed to evaluate the association between the use of mouth rinses and changes in BP. Methods: The PubMed, Web of Science, EMBASE, Scopus, and Cochrane Library databases were systematically searched from their respective inception dates to 18th December 2022 to identify potential interventional studies with information on the association between the use of mouth rinse and changes in BP. Five trials using a controlled, crossover design were identified for data analysis. Results: The weighted mean difference was pooled using a random‐effects model. The pooled results of five trials together showed that the use of mouth rinses did not result in a statistically or clinically significant increase in the systolic BP (SBP) (1.59 mmHg; 95% confidence interval [CI], −0.15 to 3.33) or diastolic BP (DBP) (0.46 mmHg; 95% CI, −0.72 to 1.64). The trial sequential analysis did not present conclusive evidence supporting the association between mouth rinse use and BP elevation. Conclusion: Within the limits of the available evidence, our review and meta‐analysis showed that mouth rinse use did not result in a statistically significant increase in the SBP, DBP, or mean arterial pressure (MAP). Nevertheless, the results should be interpreted cautiously due to the high degree of inconsistency across the studies. [ABSTRACT FROM AUTHOR]

Background This clinical study aims to evaluate the efficacy and safety of alcoholcontaining and alcohol-free mouth rinses in a controlled setting. With oral hygiene being a crucial aspect of overall health, it is essential to determine which type of mouth rinse is more effective and safer for daily use. Materials and Methods A randomized, double-blind, parallel-group study was conducted with 150 adult participants. They were divided into two groups: one using an alcohol-containing mouth rinse, and the other using an alcohol-free alternative. Participants followed a standardized oral hygiene regimen for four weeks, using their respective mouth rinses twice daily. Key parameters such as plaque reduction, gingival health, and adverse effects were assessed at baseline and after the study period. Results The results indicated a significant reduction in plaque accumulation in both groups, with the alcohol-containing mouth rinse group showing a mean reduction of 25.4% and the alcohol-free group showing a mean reduction of 23.1%. In terms of gingival health, both groups demonstrated improvement, with the alcohol-containing mouth rinse group showing a mean reduction of gingival inflammation by 19.2%, while the alcohol-free group exhibited a reduction of 18.5%. Importantly, the alcohol-free mouth rinse group reported fewer cases of adverse effects such as dry mouth and irritation compared to the alcohol-containing group. Conclusion This clinical study suggests that both alcohol-containing and alcoholfree mouth rinses are effective in reducing plaque accumulation and improving gingival health when used as part of a daily oral hygiene routine. However, the alcohol-free mouth rinse demonstrated a lower incidence of adverse effects, making it a potentially safer choice for individuals with sensitivity or a history of irritation. Further long-term studies are needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Objectives: Evaluate the strength degradation of polymeric ligature chains after their immersion in cetylpyridinium chloride-based mouthwashes. Methods: 240 elastomeric samples from four different manufacturers (Rocky Mountain®, Ormco®, Morelli® and Dentaurum®) in two types of configurations (with and without intermodular links) and divided in 3 groups (distilled water, Vitis CPC Protect® and PERIO·AID® 0.05%) at 5 follow-up periods (0–24 h, 7–14 -21 days) were immersed twice a day for 60 s, following the manufacturers' protocols. A universal traction machine was used to perform the measurements and a post hoc multiple comparisons were based on the Bonferroni test and extended to a 3-way ANOVA test (α = 0.05). Results: There was a drop in strength up to 35.9% at 24 h. After a week, the short chains (52%) degraded less than the long ones (57.3%) with significant differences (p

BackgroundFew clinical studies evaluate interventions to reduce oral discomfort among patients in palliative care.AimThis study examines the efficacy of a Salvia officinalis (SO) based herbal mouth rinse compared to conventional normal saline (NS) in order to improve oral health.DesignA block-randomized controlled trial. Data were collected before and after a 4-day intervention with either SO (n=44) or NS (n=44). Numerical rating scales (NRS, 0-10) and 12 items from the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Oral Health 17 (EORTC QLQ-OH17) measured patient-reported oral symptoms. An oral examination was performed before and after the intervention.Setting/participantsThis study included adult patients with late-stage cancer in an inpatient hospice unit.ResultsOf the 88 patients included (mean age=63.9 years, SD=10.6), 73 (83%) completed the study. At baseline, 78% reported dry mouth on the EORTC QLQ-OH17, and 80% rated dry mouth ≥4 on the NRS. Total oral health scores based on the 12 EORTC QLQ-OH17 items improved similarly in both groups (p

Abstract Background External factors such as the daily use of antimicrobial mouthwashes to maintain oral hygiene and to reduce the microbial activity can contribute to alter the mechanical properties of the elastomeric chains used during orthodontic treatments, causing loss of effectiveness. This systematic review and a meta-analysis assessed the rate of force decay and degradation of the polymeric chains depending on the type of mouthwash. Methods A systematic search of the literature were there was an exposure of orthodontic elastomeric chains to certain mouthwashes was conducted in the electronic databases of PubMed, Cochrane Library (CENTRAL), Scopus, EMBASE and Web of Science, as well as grey literature (Opengrey). No limit was placed on publication year and research was done up to June 2022. Based on inclusion/ exclusion criteria, data were extracted by two independent reviewers. For the quantitative analysis, studies were analysed with a mixed-effect (random effect) meta-regression model, with beta coefficients and R [2] values. I [2] index and Q and Egger tests were used to find heterogeneity among studies. Results A total of 178 potentially eligible studies were identified, of which 14 were eventually included in the qualitative analysis and 14 in the quantitative meta-analysis. The meta-analysis showed that all the mouthwashes were associated with a greater force decay than the control groups. After 7 days (p = 0.005) significant differences were found among the different mouthwashes, with those containing alcohol having significantly higher impact on the force decay than those containing chlorhexidine 0.2%, sodium fluoride or Persica. However, at 24 h (p = 0.200), 14 days (p = 0.076), 21 days (p = 0.120) and 28 days (p = 0.778) no statistically significant differences among the different mouthwashes were found, although those containing alcohol presented a strong tendency. Conclusion Although mouthwashes tend to increase the speed of force decay of elastomeric chains, especially those containing alcohol, clorhexidine 0.2% can be a good alternative due to its low impact on the force decay and its ability to maintain low microbial activity. More in vitro and in vivo studies comparing different manufacturers and other agents should be performed.

Objective To evaluate the effect of high-fluoride mouth rinse and high-fluoride toothpaste on the development of demineralized lesions (DLs) during orthodontic treatment. Trial design Three-armed parallel-group randomized controlled trial. Methods The trial was performed with 270 adolescent orthodontic patients. Randomization was performed in blocks of 30, enrolling the patients into one of the following groups: the fluoride mouth rinse (FMR) group receiving 0.2% sodium fluoride (NaF) mouth rinse plus 1450 ppm fluoride (F) toothpaste; high-fluoride toothpaste (HFT) group receiving 5000 ppm F toothpaste; and the Control (CTR) group receiving 1450 ppm F toothpaste. Inclusion criteria were patients scheduled for treatment in both arches with fixed appliances and age between 12 and 20 years. The primary outcome variable was the proportion of participants with at least one new demineralized lesion as assessed on digital photos taken before and after treatment, analysed by a blinded clinician. The analysis included all teeth or teeth in the aesthetic zone, i.e. all central incisors, lateral incisors, and canines. A random sample of 30 participants was assessed to check intra- and inter-reliability. For pairwise comparison between groups, Fisher's non-parametric permutation test was used for continuous variables. Blinding was employed during the caries registration and data analysis. Recruitment October 2010 to December 2012 Results In total, 270 patients were randomized, of which 22 were excluded during treatment. Therefore, 248 participants were included in the study. The number of patients with an increase of ≥1 DL, including only central- and lateral incisors and canines, during orthodontic treatment, was significantly lower in the HFT group, 51/85 60%, compared to the CTR group, 64/82 78%, RR 0.77 (CI 0.62; 0.95), P =.01 and in the FMR group, 47/81 58%, compared to the CTR group, RR 0.74 (CI 0.60; 0.92), P <.01. Conclusions To prevent demineralized lesions in the aesthetic zone, high-fluoride mouth rinse and high-fluoride toothpaste may be recommended. Limitations The protocol was not registered, and the present study did not use a double-blinded design. [ABSTRACT FROM AUTHOR]

The effects of caffeine mouth rinse (Caff-MR) on sports performance have been evaluated by recent studies presenting contrasting results. Therefore, this systematic review aimed to summarize the evidence regarding the effects of Caff-MR on sports performance. According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations, the search through PubMed, Web of Science, and Scopus databases was performed until December 2021. A random-effects meta-analysis of standardized mean differences was performed to assess the overall effect of Caff-MR on sports performancerelated outcomes. Sixteen studies met the inclusion criteria (207 participants). The meta-analysis showed no significant overall effect of Caff-MR on sports performance (p = 0.09). Moreover, no effects were shown on maximal heart rate or ratings of perceived exertion. The risk of bias for the included studies assessed using the risk of bias in randomized trials Cochrane tool presented 87.5% (n = 14) of the studies as medium and 12.5% (n = 2) as high scores. These data do not support using Caff-MR for sports performance, although more consistent and well-controlled studies are warranted. Large heterogeneity in study designs precludes making practical recommendations for exercise performance. More research is warranted to elucidate the potential of Caff-MR, specifically focusing on determining the optimal dose. [ABSTRACT FROM AUTHOR]

Objective: To compare the protective effect of commercial stannous-containing mouth rinses on enamel erosion in a simulated 5-day in vitro cycling model. Materials and methods: 81 human enamel specimens were embedded in resin blocks and divided into nine groups as follows; group 1: stannous fluoride (1000SnF2) toothpaste; groups 2,3, and 4 were the same as group 1 plus Elmex®, PerioMed™, and Meridol®, respectively, group 5: stannous fluoride (1450SnF2) toothpaste, groups 6, 7, and 8 were the same as group 5 plus Elmex®, PerioMed™, and Meridol®, respectively, group 9: negative control. An erosive challenge was induced with a 1 min hydrochloric acid (0.01 M, pH 2.2) treatment 3 times per day. Each cycle included immersing in the toothpaste slurry twice for two minutes and a one-minute rinse. The enamel slabs were immersed in artificial saliva between each erosive cycle and incubated overnight at 37 °C. Surface hardness loss and enamel loss were determined by Knoop surface hardness and non-contact profilometry, respectively. Finally, enamel surfaces were analyzed by scanning electron microscopy and X-ray energy dispersive spectroscopy (SEM/EDS). Results: All three mouth rinses had similar protective effects against erosion when using adjunct with 1000 SnF2 toothpaste (p > 0.05). With 1450 SnF2 toothpaste, Elmex® presented significantly lower surface hardness loss than Meridol® (p < 0.05). The combined use of Elmex® or PerioMed™ with toothpaste provided significantly better erosion protection than toothpaste alone, either 1000 or 1450 SnF2. In addition, 1000SnF2 toothpaste adjunct with mouth rinse is comparable to 1450 SnF2 toothpaste alone in preventing enamel erosion. Conclusion: All three mouth rinses reduced enamel erosion. The additional use of a high concentration stannous containing mouth rinse with 1450 SnF2 toothpaste increases the protective effect against enamel erosion in vitro. Clinical significance: To date, no standard protocol for preventing dental erosion is available. There are three stannous-containing mouth rinses on the market; however, no study compared their efficacy or indicated whether using adjuncts with anti-erosion toothpaste provides additional benefits. This study found that adding stannous mouth rinse to twice-daily toothpaste increases erosion protection. [ABSTRACT FROM AUTHOR]

This systematic review and network meta-analysis (NMA) comprehensively compared the effectiveness of different mouth rinses in reducing the viral load/infectivity of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) (Part I), alleviating clinical symptoms or severity of disease (Part II), and decreasing the incidence of SARS-CoV-2 infection (Part III). Randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) with restrictions were searched up to 3rd March 2023. Twenty-three studies (22 RCTs and one NRCT) met the inclusion criteria for this systematic review. Five RCTs (454 patients and nine interventions) in Part I were eligible for NMA. The NMA results showed that, in comparison with no rinse, sodium chloride (NaCl) was the most effective mouth rinse for reducing the viral load, followed by povidone-iodine (PVP-I), ß-cyclodextrin + citrox (CDCM), hydrogen peroxide (HP), chlorhexidine gluconate (CHX), cetylpyridinium chloride (CPC), placebo and hypochlorous acid (HClO). However, these results were not significant. Based on surface under the cumulative ranking curve scores, PVP-I was likely to be the most efficacious mouth rinse for reducing SARS-CoV-2 viral load, followed by CDCM, HP, NaCl, CHX, CPC, placebo, no rinse and HClO. Due to heterogeneity of the primary studies, the effectiveness of different mouth rinses to reduce viral infectivity, improve clinical symptoms or prevent SARS-CoV-2 infection remains inconclusive.

Conclusion: Although mouthwashes tend to increase the speed of force decay of elastomeric chains, especially those containing alcohol, clorhexidine 0.2% can be a good alternative due to its low impact on the force decay and its ability to maintain low microbial activity. More in vitro and in vivo studies comparing different manufacturers and other agents should be performed. [ABSTRACT FROM AUTHOR]

Purpose: To determine whether carbohydrate mouth rinsing would improve endurance running performance of tropical natives in a warm-humid (30 °C and 70% relative humidity) environment. Method: Twelve endurance male runners [age 25 ± 3 years; peak aerobic capacity ( V ˙ O2peak) 57.6 ± 3.6 mL.kg−1.min−1] completed three time-to-exhaustion (TTE) trials at ~ 70% V ˙ O2peak while swilling 25 ml of a 6% carbohydrate (CHO) or taste-matched placebo (PLA) as well as no mouth rinse performed in the control (CON) trial. Results: TTE performance was significantly longer in both CHO and PLA trials when compared with the CON trial (54.7 ± 5.4 and 53.6 ± 5.1 vs. 48.4 ± 3.6 min, respectively; p < 0.001 and p = 0.012, respectively), but was not significantly different between CHO and PLA trials (p = 1.000). The rating of perceived exertion was not different between the CHO and PLA trials, however, was significantly affected when compared to the CON trial (p < 0.001). A similar effect was observed for perceived arousal level between the CHO and PLA trials to the CON trial. Core temperature, mean skin temperature and skin blood flow were not significantly different between the three trials (all p > 0.05). Similarly, plasma lactate and glucose as well as exercise heart rate were not influenced by the trials. Conclusions: The present study demonstrates that mouth rinsing, whether carbohydrate or placebo, provides an ergogenic benefit to running endurance when compared to CON in a heat stress environment. Nevertheless, the results do not support the notion that rinsing a carbohydrate solution provides a greater advantage as previously described among non-heat acclimated individuals within a temperate condition.

Objective : This study aims to review the role of the oral cavity in SARS-CoV-2- and other viral upper respiratory tract infections. Material and methods: Data reviewed in the text have been researched online and also reflect personal expertise. Results: Numerous respiratory and other viruses replicate in the oral cavity and are transmitted via aerosols (< 5 µm) and droplets (> 5 µm). SARS-CoV-2 replication has been documented in the upper airways as well as in oral mucosa and salivary glands. These sites are also virus reservoirs that can infect other organs, e.g., the lungs and gastrointestinal tract, as well as other individuals. Laboratory diagnosis of viruses in the oral cavity and upper airways focuses on real-time PCR; antigen tests are less sensitive. For screening and monitoring infections, nasopharyngeal and oral swabs are tested; saliva is a good and more comfortable alternative. Physical means like social distancing or masks have been proven successful to reduce the risk of infection. Both wet-lab and clinical studies confirm that mouth rinses are effective against SARS-CoV-2 and other viruses. Antiviral mouth rinses can inactivate all viruses that replicate in the oral cavity. Conclusions: The oral cavity plays an important role in viral infections of the upper respiratory tract: it serves as a portal of entry, a site of replication, and a source of infection by droplets and aerosols. Physical means but also antiviral mouth rinses can help reduce the spread of viruses and contribute to infection control. [ABSTRACT FROM AUTHOR]

Objectives: Aerosols and splatter are routinely generated in dental practice and can be contaminated by potentially harmful bacteria or viruses such as SARS-CoV-2. Therefore, preprocedural mouthwashes containing antiseptic agents have been proposed as a potential measure for infection control in dental practice. This review article aims to summarize the clinical (and, if insufficient, preclinical) evidence on preprocedural mouthwashes containing antiseptic agents and to draw conclusions for dental practitioners. Methods: Literature on preprocedural mouthwashes for reduction of bacterial or viral load in dental aerosols was searched and summarized. Results: Preprocedural mouthwashes, particularly those containing chlorhexidine digluconate (CHX), cetylpyridinium chloride (CPC), or essential oils (EO), can significantly reduce the bacterial load in dental aerosols. With respect to viruses such as HSV-1, there are too little clinical data to draw any clear recommendations. On the other hand, clinical data is consolidating that CPC-containing mouthwashes can temporarily reduce the intraoral viral load and infectivity in SARS-CoV-2 positive individuals. Nevertheless, potential risks and side effects due to regular antiseptic use such as ecological effects or adaptation of bacteria need to be considered. Conclusions: The use of preprocedural mouthwashes containing antiseptics can be recommended according to currently available data, but further studies are needed, particularly on the effects on other viruses besides SARS-CoV-2. When selecting a specific antiseptic, the biggest data basis currently exists for CHX, CPC, EO, or combinations thereof. Clinical relevance: Preprocedural mouthwashes containing antiseptics can serve as part of a bundle of measures for protection of dental personnel despite some remaining ambiguities and in view of potential risks and side effects.

Objective: To assess the clinical anti-inflammatory and antimicrobial efficacy of Nigella sativa oil compared with chlorhexidine in patients with gingivitis. Methods: A double-blind, randomized clinical trial was conducted in patients having chronic generalized gingivitis. Patients were randomly assigned to receive Nigella sativa oil (n=18) or chlorhexidine (n=19). The following assessments were made on day 0 and day 15: plaque index, gingival index, gingival IL-6 and IL-18 levels were measured using ELISA, plaque colony-forming units, and alpha-hemolytic Streptococcus strains. Data were analyzed using parametric and non-parametric tests and Fisher's exact test. Results: Both interventions reduced plaque index and gingival index scores (P0.05). The post-intervention plaque index and gingival index scores and inflammatory cytokine levels between the two groups were not significantly different. Both interventions caused a significant reduction in the plaque colony-forming units (P

Oral mucositis is the most common and severe non-hematological complication associated with cancer radiotherapy, chemotherapy, or their combination. Treatment of oral mucositis focuses on pain management and the use of natural anti-inflammatory, sometimes weakly antiseptic mouth rinses in combination with optimal oral cavity hygiene. To prevent negative effects of rinsing, accurate testing of oral care products is necessary. Due to their ability to mimic realistic in-vivo conditions, 3D models may be an appropriate option in compatibility testing of anti-inflammatory and antiseptically effective mouth rinses. We present a 3D model of oral mucosa based on the cell line TR-146 with a physical barrier, characterized by high transepithelial electrical resistance (TEER) and confirmed cell integrity. Histological characterization of the 3D mucosa model showed a stratified, non-keratinized multilayer of epithelial cells similar to that of human oral mucosa. By means of immuno-staining, tissue-specific expression of cytokeratin 13 and 14 was shown. Incubation of the 3D mucosa model with the rinses had no effects on cell viability, but TEER decreased 24h after incubation in all solutions except ProntOral®. Analogous to skin models, the established 3D model meets the quality control criteria of OECD guidelines and may therefore be suitable for comparing the cytocompatibility of oral rinses.

Objective: To assess the clinical anti-inflammatory and antimicrobial efficacy of Nigella sativa oil compared with chlorhexidine in patients with gingivitis. Methods: A double-blind, randomized clinical trial was conducted in patients having chronic generalized gingivitis. Patients were randomly assigned to receive Nigella sativa oil (n=18) or chlorhexidine (zi=19). The following assessments were made on day 0 and day 15: plaque index, gingival index, gingival IL-6 and IL-18 levels were measured using ELISA, plaque colony-forming units, and alpha-hemolytic Streptococcus strains. Data were analyzed using parametric and non-parametric tests and Fisher's exact test. Results: Both interventions reduced plaque index and gingival index scores (P<0.000 1). The Nigella sativa oil group was better at lowering IL-6 (P=0.007 6) than the chlorhexidine group (P=0.145), although there was no change in IL-18 levels (P>0.05). The post-intervention plaque index and gingival index scores and inflammatory cytokine levels between the two groups were not significantly different. Both interventions caused a significant reduction in the plaque colony-forming units (PcO.OOO1), reducing pathogenic bacteria: Streptococcus mitis, Streptococcus oralis, Streptococcus sanguinis, and Streptococcus parasanguinis in the chlorhexidine group (50%) (P=0.103 1), and the Nigella sativa oil group (20%) (P=0.7395). Conclusions: Nigella sativa oil had anti-inflammatory and antibacterial activities, reducing biofilm formation and disrupting the colonization of pathogenic bacteria essential for the progression of periodontal disease. Nigella sativa oil could offer an alternative therapy for treating gingivitis and may prevent associated systemic diseases and improve overall health outcomes. [ABSTRACT FROM AUTHOR]

Abstract Polyphenols interact with salivary proteins and thus can improve the pellicle’s erosion protective properties. This effect could be exploited to create rinsing solutions with polyphenols as active ingredients for erosion prevention. Different from the current gold standard for erosion protective rinsing solutions, these rinses would not rely on stannous ions. This would offer alternatives for patients with concerns regarding the composition of rinsing solutions and preferring bio-products. Objective To develop an erosion-preventive rinsing solution containing natural polyphenol-rich extracts. Methodology Solutions were prepared with polyphenols from either grapeseed extract or cranberry extract, 500 ppm fluoride added, and additionally flavors and sweeteners. Controls were deionized water, 500 ppm fluoride solution, and the gold standard rinse in the field (Sn2+/F-). In total, 135 enamel specimens (n=15/group) were subjected to five cycles of salivary pellicle formation (30 min, 37°C), modification with the solutions (2 min, 25°C), further salivary pellicle formation (60 min, 37°C), and erosive challenge (1 min, 1% citric acid, pH 3.6). Relative surface microhardness (rSMH), surface reflection intensity (rSRI), and amount of calcium release (CaR) were investigated. Data were analyzed with Kruskal-Wallis and Wilcoxon rank sum tests (α=0.05). Results The polyphenol solutions containing fluoride, as well as additional flavors, protected enamel better than fluoride alone, and similar to the Sn2+/F- solution, when investigating both rSMH and CaR. When measuring rSRI, Sn2+/F- showed the best protection, while the polyphenol solutions were similar to fluoride. Conclusion For two of the three assessed parameters (rSMH and CaR), both developed polyphenol-rich rinsing solutions were able to protect enamel from erosion, improving/potentializing the effect of fluoride and matching the protection offered by the current gold standard rinsing solution.

ABSTRACT: Aims: The objective of this study was to evaluate the posttreatment effects of a school-based fluoride mouth-rinsing programme (FMR) on the prevalence of dental caries. Methods: We included 364 newly enrolled university students aged 20 to 25 years who were not in any FMR and 187 students who had previously participated in such programmes. We calculated the prevalence of dental caries in permanent teeth and the mean decayed, missing, and filled surfaces (DMFS) according to sex, age, participation in FMR, and dental health behaviours. A multivariate logistic regression model was used to analyse the association between dichotomous variables (caries present or absent) and demographic data, participation in FMR, and dental health behaviours. Results: The difference in the prevalence of dental caries in permanent teeth between the subjects who participated in the FMR (51.3%) and those who did not (64.5%) was statistically significant. There were 39.6% fewer DMFS in the subjects who participated in the FMR at least during elementary school. The multivariate logistic regression model analysis demonstrated that subjects who participated in the FMR at least during elementary school were protected against dental caries as compared to those who did not. Age and sex were risk predictors of dental caries in adults, whilst other variables were not associated with dental caries. Conclusions: Participation in an FMR at least during elementary school is a predictor for the reduction in the prevalence of dental caries in permanent teeth.

Background: In daily dental practice, plaque‐induced gingivitis is one of the most common periodontal diseases that is frequently encountered. Accumulation of microbial biofilms on surfaces of teeth and poor or inadequate oral hygiene is the chief predisposing factor for this condition. In such a state, antimicrobial mouthwash as an adjunct to mechanical plaque control helps in maintaining good oral hygiene. Among the many conditions, fixed orthodontic treatment is one of the conditions where plaque control becomes challenging to the patient as well as the dentist. In such a situation, antimicrobial mouthwash as an adjunct to mechanical plaque control is highly recommended. Dentistry has recently evidenced a shift of approach for treating many inflammatory oral diseases by using herbal treatment modalities. Aloe vera is one such product exhibiting multiple benefits and has gained considerable importance in clinical research recently. The present study aimed to evaluate efficacy of aloe vera mouth rinse on the dental plaque and gingivitis in patients who were undergoing fixed orthodontic treatment in comparison with 0.2% chlorhexidine mouthwash. Material and Method: This randomized controlled trial was conducted on 30 subjects with fixed orthodontic treatment. The subjects were grouped in the test group (15 subjects with 10 ml aloe vera mouthwash (99.6% [w/v])) and the control group (15 subjects with 0.2% 10 ml chlorhexidine mouthwash). Plaque index, gingival index and bleeding on probing were recorded for each participant at baseline, 21 days from baseline and 35 days from baseline. The findings were then statistically analysed using student paired and unpaired t‐test. Results: Gingival index showed a statistically significant difference from baseline to 21 days and 35 days visit in both the groups. Plaque index and bleeding on probing were statistically significant among both groups when compared baseline to 21 days and 35 days visit, but the difference was not significant between visit 2 and visit 3. Conclusions: Although chlorhexidine is still the gold standard mouthwash, aloe vera exhibits promising results in reducing plaque and gingivitis scores, without any reported adverse effects. Larger multi‐centric trials are needed to prove its effectiveness on dental plaque‐induced gingivitis. [ABSTRACT FROM AUTHOR]

Study aim: The purpose of this study was to evaluate the acute effect of different four caffeine mouth rinse intervention (caffeinated coffee, decaffeinated coffee, placebo, control) on attention and hand-eye coordination.

Introduction: Recurrent aphthous stomatitis (RAS) is one of the most common ulcerative diseases affecting the general population. The present study aimed to evaluate the clinical efficiency of 0.5% minocycline mouth rinse prescribed along with the topical anesthetic gel and vitamin supplement over the topical anesthetic gel and vitamin supplement prescribed alone for treating RAS. Materials and Methods: A total of 60 participants were randomly divided into two groups—experimental group: 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel; and control group: vitamin supplement and topical anesthetic gel alone. The pain symptoms were evaluated using the VAS scores at baseline and first follow-up visits. The data were analyzed using Student's t test. Results: A significant reduction in the pain scores was observed in participants using the 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel on the first follow-up visit (P = < 0.001). Conclusion: The 0.5% minocycline mouth rinse prescribed along with vitamin supplement and topical anesthetic gel had shown more reduction in the pain symptoms when compared to topical anesthetic gel and vitamin supplement prescribed alone for the treatment of RAS.

Detection of p16 through immunohistochemistry (IHC) is the standard for determining the HPV status of the tumor according the TNM eighth edition released in 2017 and has become crucial for determining the HPV status of oropharyngeal squamous cell carcinomas (OPSCC) with direct impact on staging and prognostication. In recent years, detection of HPV DNA in mouthwashes has been proposed as a noninvasive alternative, both for OPSCCs and for other head and neck squamous cell carcinomas (HNSCCs). However, the prospect of using the mouthwashes to monitor the response to therapy is unclear. To evaluate the effect of curative therapy on the detection of HPV DNA, we performed a prospective study comparing the detection frequency of high-risk HPV DNA (HR-HPV-DNA) in pre- and post-therapy mouthwashes. We collected 137 mouthwashes from 88 pathologically confirmed HNSCC patients for DNA isolation and HPV genotyping with the Inno-LiPA assay. We show that HPV DNA in pretherapeutic mouthwashes can detect HPV-driven HNSCCs with a sensitivity of 50.0% and specificity of 85.4%, alongside a high negative predictive value of 79.5% and an accuracy of 74.5%. Furthermore, we observed a notable decrease in the detection frequency of HR-HPV-DNA after successful treatment (pre-therapy 50.0% (9/18) versus post-therapy 9.7% (3/28)). However, the comparatively low sensitivity regarding detection of HPV-driven OPSCC argues against its use in clinical routine. [ABSTRACT FROM AUTHOR]

This systematic review aims to evaluate the evidence on the efficacy of mouth rinses on SARS-CoV-2 from in vitro studies. Five electronic databases were searched up to February 2021; no language or time restrictions were used. Two independent reviewers conducted both selection and data extraction processes. The toxicological data reliability assessment tool was used to evaluate the risk of bias. Starting from 239 articles, retrieved by the electronic search, only eight studies were included in our systematic review. Povidone Iodine (PVP-I) was effective in killing SARS-CoV-2, demonstrated higher virucidal activity than other commonly used active ingredients. Conflicting results were found about the effectiveness of Chlorhexidine (CHX) while hydrogen peroxide (H2O2) proved less effective than PVP-I. Other active ingredients, such as quaternary ammonium compounds and Ethanol (particularly when combined with essential oils), have also shown promising results in reducing viral load, with results comparable to PVP-I.

This systematic review aimed to evaluate existing randomized controlled trials (RCT) and cohort studies on the efficacy of mouthwashes in reducing SARS-CoV-2 viral loads in human saliva.Searches with pertinent search terms were conducted in PubMed, MEDLINE, Scopus, and Web of Science databases for relevant records published up to Oct 15, 2022. Google Scholar and ProQuest were searched for grey literature. Manual searches were conducted as well for any pertinent articles. The protocol was prospectively registered at PROSPERO (CRD42022324894). Eligible studies were critically appraised for risk of bias and quality of evidence to assess the efficacy of mouthwash in reducing the SARS-CoV-2 viral load in human saliva.Eleven studies were included. The effect on viral load using various types of mouthwash was observed, including chlorhexidine (CHX), povidone-iodine (PI), cetylpyridinium chloride (CPC), hydrogen peroxide (HP), ß-cyclodextrin-citrox mouthwash (CDCM), and Hypochlorous acid (HCIO). Eight articles discussed CHX use. Five were found to be significant and three did not show any significant decrease in viral loads. Eight studies reviewed the use of PI, with five articles identifying a significant decrease in viral load, and three not showing a significant decrease in viral load. HP was reviewed in four studies, two studies identified significant viral load reductions, and two did not. CPC was reviewed in four studies, two of which identified significant viral load reductions, and two did not. CDCM was reviewed in one article which found a significant decrease in viral load reduction. Also, HCIO which was evaluated in one study indicated no significant difference in CT value.The current systematic review indicates that based on these eleven studies, mouthwashes are effective at reducing the SARS-CoV-2 viral load in human saliva. However, further studies should be performed on larger populations with different mouthwashes. The overall quality of evidence was high.

Objective: Oral candidiasis is an opportunistic fungal infection in the oral cavity caused by an overgrowth of Candida species, especially Candida albicans. Various herbal agents have been designed to target Candida albicans. The aim of this study was to evaluate the antifungal activity of Jaftex mouthwash and nystatin suspension on the growth of Candida albicans. Methods and materials: In the present in vitro study, a standard strain of Candida albicans was prepared in the form of lyophilized ampoules. Jaftex mouthwash was prepared with an active ingredient (10 g per 100 cc) of aqueous extract of oak fruit hull (Jaft), Zataria multiflora and Satureja bachtiarica. Nystatin oral suspension (100,000 IU/mL) was also prepared. Both mouthwashes were serially diluted using the two-fold serial dilution method (Jaftex: eight-fold dilutions; nystatin suspension: nine-fold dilutions). A volume of 10 µL of each dilution of Jaftex mouthwash and nystatin suspension was placed on the discs that were linearly inoculated on culture medium and stored in an incubator for 24 hours at 37 °C. The minimum inhibitory concentration (MIC) of the two antifungal agents was determined using the modified E-test. Data were analyzed using SPSS Version 26.0. A p-value less than 0.05 was considered statistically significant. Results: The mean MIC values of Jaftex mouthwash and nystatin suspension were 0.0625 (mg/mL) and 0.0015 (mg/mL), respectively. There was a significant difference between the antifungal effect of Jaftex mouthwash and nystatin suspension on the growth of Candida albicans. Nystatin showed the lowest MIC and greater antifungal activity compared with Jaftex mouthwash. Conclusion: Nystatin increasingly suppressed the growth of Candida albicans. Jaftex mouthwash inhibited the growth of Candida albicans. Since nystatin may show allergic reactions, Jaftex mouthwash can be used as an alternative to nystatin. Due to the synergistic effect of nystatin with thymol, Jaftex mouthwash can be prescribed with nystatin. [ABSTRACT FROM AUTHOR]

This study used polymeric micelles to improve quality by increasing drug solubility, extending mucosal drug retention time, enhancing mucoadhesiveness, and promoting drug permeation and deposition. Fluocinolone acetonide (FA) was loaded into polymeric micelles (FPM), which were composed of poloxamer 407 (P407), sodium polyacrylate (SPA), and polyethylene glycol 400, and their physicochemical properties were examined. Small-angle X-ray scattering (SAXS) revealed a hexagonal micellar structure at all temperatures, and the concentrations of P407 and SPA were shown to significantly affect the solubility, mucoadhesion, release, and permeation of FPMs. The proportion of P407 to PEG at a ratio of 7.5:15 with or without 0.1% w/v of SPA provided suitable FPM formulations. Moreover, the characteristics of FPMs revealed crystalline states inside the micelles, which was consistent with the morphology and nano-hexagonal structure. The results of ex vivo experiments using focal plane array (FPA)-based Fourier transform infrared (FTIR) imaging showed that the FPM with SPA penetrated quickly through the epithelium, lamina propria, and submucosa, and remained in all layers from 5–30 min following administration. In contrast, the FPM without SPA penetrated and passed through all layers. The FPM with extended mucoadhesion, improved drug–mucosal retention time, and increased FA permeation and deposition were successfully developed, and could be a promising innovation for increasing the efficiency of mouth rinses, as well as other topical pharmaceutical and dental applications.

ObjectiveThe goal of this study was to evaluate the enamel whitening effects of 2 new test formulations, one of which was a rinse, and the other a whitening strip.Materials and methodsForty enamel chips were prepared from 20 healthy extracted teeth (2 from each tooth). After pre-staining and colorimetry to measure L* and b* values, 20 matched samples were immersed in either test or control rinses, and then colorimetry was performed again after 1 hr, 2 hr, 3 hr, 6 hr, 12 hr, 24 hr and 48 hrs (Each hour equates to one month of clinical use at the recommended dosage of 1 minute exposure 2 times a day). The remaining 20 matched samples were exposed to the test or control whitening strips and colorimetry was performed every 30 minutes for a total of 10 treatments.ResultsOverall, the whitening performance of test and control strips was similar. The test and control rinses had a similar lightening effect over the first 3 hours (equivalent to 3 months of clinical use). Subsequently, the control rinse continued to lighten samples, whereas the test rinse had little further effect.ConclusionTest and control-whitening strips showed similar effects; over time whitening strips showed a greater lightening effect than whitening rinses.

Opinion statement: Oral mucositis (OM) causes significant detriment to patient quality of life. Despite advances in RT, chemotherapy, and surgery for HNC which have led to improved local control and survival, management of certain toxicities such as OM have not kept pace. Numerous strategies have emerged with demonstrable benefit in preventing severe OM. However, ones which are not only effective, but practical and affordable to implement are rare. For example, infusion of growth factors or free radical scavengers, and daily treatment of intra-oral sites with lasers are supported by high-quality evidence but have not become widely adopted. It falls to familiarity of the physician with the available preventative measures and ultimately, patient preference in accepting which strategies for OM amelioration are used. In this review, we present a pathophysiological-based review of prevention techniques available for reducing the incidence and duration of severe OM. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study was to evaluate the effectiveness of a prototype photocatalytic device for bacterial decontaminations of the oral cavity. Methods: Sixty-four subjects (18–65) were selected and randomly assigned to eight groups (n = 8), according to oral disinfection protocol: (G1): distilled water (control); (G2): 1.5% hydrogen peroxide (HP); (G3): 3.0% HP; (G4): 0.12% chlorhexidine (CHX); (G5): Germinator; (G6): 1.5% HP + Germinator; (G7): 3.0%HP + Germinator; (G8): 0.12% CHX + Germinator. Stimulated saliva was collected before and after a 3-min mouthwash and/or Germinator application. The patients were kept relaxed and retained saliva 5–10 min, spitting out into the tube for 3 min. The percentage bacterial reduction was checked by counting the colony-forming units (CFUs) after culturing on blood agar plates. Data were subjected to one-way ANOVA followed by Tukey's post hoc test (α = 5%) for statistical significance. Results: The highest bacterial reduction was observed in groups 3 (3.0% HP), 6 (1.5% HP + Germinator), and 7 (3.0% + Germinator), with no statistically significant difference between them (p > 0.05). Groups 6 (1.5% HP + Germinator) and 8 (0.12% CHX + Germinator) showed higher bacterial reduction than groups 2 (1.5% HP) and 4 (0.12% CHX) (p < 0.05). Finally, group 5 (Germinator) showed higher bacterial reduction than control group (DW) and group 4 (0.12% CHX) (p < 0.05). Conclusions: The photocatalytic disinfection was effective against oral bacteria and improved the antimicrobial action of 1.5% HP and 0.12%. Clinical significance. The photocatalytic disinfection can be an alternative protocol to provide the oral decontamination. [ABSTRACT FROM AUTHOR]

Background: Mouthwashes containing essential oils are used in the prevention and treatment of periodontal diseases. Lemongrass oil (LGO) belongs to a section of andropogen called cymbogam of the family germineae and from it, the LGO is extracted. Tea tree oil (TTO) is extracted from Melaleuca alternifolia leaves (Myrtaceae family). Aim and Objective: The aim of the study is to evaluate the pH of saliva before and after using LGO and TTO mouth rinse and to determine its relevance to the oral health status. Materials and Methods: A purposive sample of 90 participants aged between 26 and 38 years were included in the study. The PH before and after the use of the chlorhexidine, LGO, and TTO mouthwashes are noted using the GC PH strips and a comparative study was made. Statistical analysis was performed using paired t-test. P < 0.05 was considered statistically significant. Results: Comparative analysis was made with Wilcoxon signed-ranks test and found that the TTO gives a greater increase in salivary pH with a P = 0.001** (P < 0.05) which is found to be statistically significant. Conclusion: The study conducted shows beneficial effects of TTO and LGO mouth rinse. Further studies with larger samples may produce more reliable values.

Background. This study compared the force decay pattern of two different orthodontic active tiebacks (ATBs) exposed to five different commercially available mouth rinses. Methods. In this in vitro study, 90 transparent ATBs and 90 gray ATBs were divided into six groups; one was the control group, and the others were exposed to one of these mouth rinses twice a day for 60 seconds: Listerine, chlorhexidine, Orthokin, Persica, and fluoride. The initial force of each ATB was 250 g at a 24-mm extension. The force of ATBs was measured on days 1, 7, 14, and 28 using a digital gauge. Results. The highest percentage of force loss was observed between days 14 and 28 (P

The high consumption of alcoholic drinks has become acceptable in many societies and is often promoted by commercials. Unfortunately, many people risk their lives by driving drunk. They even try to outsmart breathalyzer tests, for example, using a novel procedure based on the partial oxidation of expired breathed ethanol after rinsing the mouth with diluted hydrogen peroxide. To check the validity of this procedure, the different variables involved in the process were tested: the type of alcoholic beverage, the amount of ethanol swallowed, and the time elapsed between consumption and mouth rinsing. Our ultimate aim was to measure the effects of this process. If the mouth rinse succeeds in masking a drinker's true alcohol level, then further study of possible remedies is needed to prevent such fraud. However, if the rinsing proves to have no effect, then this work could help strengthen the integrity of the breathalyzer test and its ability to deter drivers from overdrinking. The final conclusion, after all the experiments, is that a reduction in the alcohol level is observed with the use of hydrogen peroxide as a mouthwash before performing a breathalyzer test.

Background: Carbohydrate (CHO) and caffeine (CAF) mouth rinsing have been shown to enhance endurance and sprint performance. However, the effects of CHO and CAF mouth rinsing on muscular and cognitive performance in comparison between male and female athletes are less well-established. The aim of this study was to examine the effect of CHO and CAF rinsing on squat and bench press 1 repetition maximum (1-RM) strength, 3 sets of 40% of 1-RM muscular endurance and cognitive performance in both male and female athletes. Methods: Thirteen male and fourteen female resistance-trained participants completed four testing sessions following the rinsing of 25 ml of i) 6% of CHO (1.5 g); ii) 2% CAF (500 mg), iii) combined CHO and CAF (CHOCAF) solutions or iv) water (PLA) for 10 s. Heart rate (HR), felt arousal (FA), ratings of perceived exertion (RPE) and glucose (GLU) were recorded throughout the test protocol. Results: There were no significant differences in squat and bench press 1-RM, HR, RPE and GLU (p > 0.05) for males and females, respectively. FA was significantly increased with CAF (p = 0.04, p = 0.01) and CHOCAF (p = 0.03, p = 0.01) condition in both males and females, respectively. Squat endurance performance in the first set was significantly increased with CHOCAF condition compared to PLA in both males (p = 0.01) and females (p = 0.02). Bench press endurance was similar for all conditions in both genders (p > 0.05). Cognitive performance was significantly increased with CHOCAF compared to PLA in males (p = 0.03) and females (p = 0.02). Conclusion: Combined CHO and CAF mouth rinsing significantly improved lower body muscular endurance and cognitive performance in both males and females. [ABSTRACT FROM AUTHOR]

Abstract Background The aim of this in vitro study was to examine the possible enhancement of the biofilm peeling effect of a sonic toothbrush following the use of an antimicrobial mouth rinse. Methods The biofilm at a noncontact site in the interdental area was treated by sound wave convection with the test solution or by immersion in the solution. The biofilm peeling effect was evaluated by determining the bacterial counts and performing morphological observations. A Streptococcus mutans biofilm was allowed to develop on composite resin discs by cultivation with stirring at 50 rpm for 72 h. The specimens were then placed in recesses located between plastic teeth and divided into an immersion group and a combination group. The immersion group was treated with phosphate buffer, chlorhexidine digluconate Peridex™ (CHX) mouth rinse or Listerine® Fresh Mint (EO) mouth rinse. The combination group was treated with CHX or EO and a sonic toothbrush. Results The biofilm thickness was reduced by approximately one-half compared with the control group. The combination treatment produced a 1 log reduction in the number of bacteria compared to the EO immersion treatment. No significant difference was observed in the biofilm peeling effect of the immersion group compared to the control group. Conclusions The combined use of a sonic toothbrush and a mouth rinse enhanced the peeling of the biofilm that proliferates in places that are difficult to reach using mechanical stress.
