Purpose: Flossing is a well-known component of daily recommended oral care regimens, but patients often find it challenging to perform effectively on a regular basis. The purpose of this 12-week supervised clinical trial was to investigate the effects of twice daily rinsing with a mouthrinse containing a fixed combination of four essential oils (4EO) and supervised daily dental flossing regimens as compared to a negative control 5% hydroalcohol rinse (NC) on the prevention and reduction of plaque, gingivitis, and gingival bleeding. Methods: Volunteer participants who met the inclusion criteria were randomized into the following groups for the 12week trial: 1) NC; 2) mouthrinse containing 4EO; 3) professional flossing performed by a dental hygienist (FBH); 4) supervised self-flossing (FUS). All participants received a professional dental prophylaxis prior to beginning the trial. On weekday mornings, all participants brushed on site. After brushing, the rinse groups used their products under supervision, and the floss groups had their teeth flossed by a dental hygienist or self-flossed under supervision. Participants performed their assigned regimen in the evenings and the twice-daily weekend use at home. Each individual assessment of oral hard and soft tissue, plaque, gingivitis, and gingival bleeding at weeks 4 and 12, probing depth and bleeding on probing at week 12 was made by the same calibrated examiner. Results: Of 156 randomized participants, 149 completed the trial. Use of the 4EO mouthrinse statistically significantly reduced plaque, gingivitis, and gingival bleeding on probing after 12 weeks as compared to the NC rinse. Both flossing interventions statistically significantly reduced interproximal gingivitis and gingival bleeding at 12 weeks compared to the NC rinse; neither flossing intervention significantly reduced interproximal plaque after 12 weeks compared to the NC rinse. Conclusions: Rinsing with a 4EO mouthrinse statistically significantly improved all oral health outcome measures at all time points compared to a NC rinse in this 12-week clinical trial. While professional and supervised flossing improved gingival health compared to use of the NC rinse, statistically significant plaque reduction with dental flossing was not attained at the end of the 12-week trial.

Purpose: Effective use of mechanical plaque control devices can depend on individual manual dexterity levels. The purpose of this component of a 12-week, virtually-supervised clinical trial was to investigate the role of manual dexterity on clinical outcomes for gingivitis, as measured by the relationship between manual dexterity scores on the Purdue Pegboard Test (PPT) and the effects of various mechanical and chemotherapeutic oral hygiene regimens. Methods: This was a single-center, examiner blinded, randomized, four-treatment arm, parallel group, 12-week plaque and gingivitis study. At baseline, healthy adult volunteers with evidence of gingivitis were assessed for manual dexterity and were then examined for plaque, gingivitis and bleeding. After a dental prophylaxis, participants were randomized into four treatment groups: brush only (BO); brush/rinse (BR); brush/floss (BF); and brush/floss/rinse (BFR). The flossing groups received instruction in flossing. The PPT was used to assess manual dexterity and was performed by a licensed occupational therapist. Virtual supervision was required once each weekday and the oral hygiene regimen was unsupervised on evenings and weekends. Results: Of the 213 subjects enrolled, 209 completed the trial. Improvements from baseline to week 12 in interproximal percent nonbleeding healthy sites (Expanded Bleeding Index (EBI)=0 and Modified Gingival Index (MGI)=0 or 1) were dependent on the participant's dexterity score. Participants with the lowest dexterity scores (9 or lower) in the BFR treatment group demonstrated the greatest improvement interproximally based on the indices (EBI and MGI). In comparison, the BF test group subjects with dexterity scores 9 or lower had limited change in improvement interproximally. There was a direct correlation between flossing effectiveness and dexterity scores. Conclusions: Less manual dexterity can limit dental flossing effectiveness. Flossing is a difficult daily task that requires functional bilateral dexterity to be perform correctly. Individuals with lower levels of manual dexterity were shown to benefit from the addition of an essential oil mouthrinse to a regimen of toothbrushing and flossing in this clinical trial. The addition of an essential oil mouthrinse improved interproximal gingival health and mitigated the manual dexterity variable. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this survey was to investigate how flossing and rinsing behaviors impact individual beliefs about oral disease risk, the efficacy of floss and mouthrinse, and the perceived benefits and barriers of floss and mouthrinse. Methods: Participants in this required component of a 12-week plaque and gingivitis randomized clinical trial on flossing and rinsing regimens completed a paper questionnaire prior to randomization and baseline/screening measurements. Results: All of the clinical trial participants (n=213) completed the questionnaire. Respondents were grouped as habitual or non-habitual users of floss or mouthrinse if the product was used at least once daily; 16% (n=34) were habitual users of floss and 17% (n=36) were habitual users of mouthrinse. Perceived barriers included fear of gingival bleeding and pain, forgetting, and not including flossing or rinsing as part of the daily oral care routine. Non-habitual users were less likely to believe in the intangible benefits of flossing or rinsing and much more likely to perceive barriers to using floss or mouthrinse. Risk perception of developing oral disease was not shown to predict product usage. Respondents viewed their risk of developing gingivitis as relatively low despite this diagnosis being confirmed clinically among the participants. Conclusion: While respondents strongly believed that brushing, flossing, and mouthrinse use carry unique benefits and that combining all three methods would be optimal, these respondents still had high perceived barriers to using floss and mouthrinse regularly and consequently these habits were not included in their daily oral hygiene regimen. Understanding the perceptions regarding oral health behaviors may help drive more effective interventions and assist practitioners in improving their patients' oral health outcomes.

Purpose: Various mechanical and chemotherapeutic methods are used to control dental plaque accumulation and prevent or reduce gingivitis. The purpose of this 12-week clinical trial was to investigate the effects of various combinations of supervised mechanical and chemotherapeutic regimens on the prevention and reduction of plaque, gingivitis, and gingival bleeding. Methods: Volunteers presenting with some evidence of gingivitis and no severe periodontitis were randomized into four groups: brush only (BO); brush/rinse (BR); brush/floss (BF); brush/floss/rinse (BFR) for this examiner-blinded clinical trial. Toothbrush, toothpaste, floss and a mouthrinse containing a fixed combination of four essential oils (EO) and training/ instructions were provided to participants as per their assigned group. Participants performed their regimen at home, under virtual supervision, once each weekday; the second daily and weekend uses were unsupervised. Assessments included oral hard and soft tissue, plaque, gingivitis, and gingival bleeding (weeks 4, 12); probing depth and bleeding on probing (week 12). Results: Of 213 enrolled participants, 209 completed the study. After 12 weeks, plaque, gingivitis, and gingival bleeding were significantly reduced in groups BR (35.8%, 50.8%, and 71.0% respectively, p<0.001) and BFR (32.8%, 54.1%, and 78.2% respectively, p<0.001) compared to BO. After 12 weeks, gingivitis and gingival bleeding were significantly reduced in the BF group (9.2%, p=0.013 and 17.5%, p=0.003, respectively), however there were no significant reductions in plaque in the BF group as compared to the BO group (p=0.935). Conclusions: Oral care regimens that included a mouthrinse containing a fixed combination of four EOs (BR and BFR), demonstrated statistically significantly reduced plaque, gingivitis, and gingival bleeding as compared to BO and BF after 12 weeks. The BF regimen statistically significantly reduced gingivitis and gingival bleeding but did not statistically significantly reduce plaque compared to BO after 12 weeks. [ABSTRACT FROM AUTHOR]
