RESUMO
BACKGROUND: The efficacy of several variants of essential oil mouthrinses has been studied extensively. This is the first study to compare the anti-plaque and anti-gingivitis efficacy of two marketed essential oil mouthrinses: one is an alcohol containing mouthrinse and the other one is an alcohol-free mouthrinse. METHODS: This examiner-blind, parallel-group study randomized subjects to three groups: 1) Mechanical Oral Hygiene (MOH) only; 2) MOH plus Alcohol-Containing essential oil Mouthrinse (ACM); 3) MOH plus Alcohol-Free essential oil Mouthrinse (AFM). Primary endpoint was whole-mouth mean Modified Gingival Index (MGI) at six months. Secondary endpoints included whole-mouth mean MGI at one and three months, and whole-mouth mean Plaque Index (PI) and whole-mouth mean Bleeding Index (BI) at one, three and six months. Safety assessments were conducted at all time points. RESULTS: A total of 370 subjects were enrolled; 348 subjects completed the study. After six months, subjects using essential oil mouthrinses with or without alcohol showed significant reduction (p < 0.001) in gingivitis (28.2% and 26.7%, respectively) and significant reduction (p < 0.001) in plaque (37.8% and 37.0%, respectively), compared to those performing MOH only. Significant reductions in MGI, PI, and BI (p < 0.001) were observed at one and three months and also at six months for mean BI. No statistically significant differences were observed for all measured indices between ACM and AFM groups at any time point. Both mouthrinses were well tolerated. CONCLUSIONS: No significant differences were observed in the efficacy of ACM and AFM to reduce plaque and gingivitis, when used in addition to MOH, over six months. TRIAL REGISTRATION: The trial was registered on clinicaltrials.gov on November 30, 2016. The registration number is NCT02980497 .

BACKGROUND: Standard recommendations for oral hygiene practices have focused on mechanical methods (toothbrushing and interdental cleaning). Published evidence indicates antimicrobial mouthrinses provide oral health benefits beyond mechanical methods alone. The purpose of this meta-analysis was to evaluate the combined effectiveness of mechanical methods with essential oil-containing mouthrinses (MMEO) versus mechanical methods (MM) alone in achieving site-specific, healthy gingival tissue and reducing plaque and gingivitis. TYPES OF STUDIES REVIEWED: All industry-sponsored clinical trials investigating the antigingivitis and antiplaque effects of essential oil (EO)-containing mouthrinses conducted from 1980 to 2012 were reviewed; 29 of 32 studies met the inclusion criteria of 6 months or longer duration, randomized, observer-masked, placebo-controlled, and with individual-level site-specific data. By-study treatment effects were estimated through generalized linear models for binary data and analysis of covariance for continuous data, and then combined using standard meta-analysis techniques; heterogeneity was also assessed. RESULTS: Summary odds ratios for a healthy gingival site and for a plaque-free site were, respectively, 5.0 (95% confidence interval [CI], 3.3-7.5) and 7.8 (95% CI, 5.4-11.2) for MMEO participants versus MM participants at 6 months. The summary percentage reductions in whole-mouth mean gingivitis and plaque at 6 months were 16.0 (95% CI, 11.3-20.7) and 27.7 (95% CI, 22.4-32.9), respectively. Responder analyses using aggregate individual-level data showed 44.8% of MMEO participants and 14.4% of MM participants achieved at least 50% healthy sites in their mouths at 6 months. Similarly, 36.9% of MMEO participants and 5.5% of MM participants achieved at least 50% plaque-free sites in their mouths at 6 months. CONCLUSIONS AND PRACTICAL IMPLICATIONS: This is the first meta-analysis to demonstrate the clinically significant, site-specific benefit of adjunctive EO treatment in people within a 6-month period (that is, between dental visits).

OBJECTIVE: The aim of this randomized clinical trial was to evaluate the efficacy of a mouthrinse containing 1.4% potassium oxalate (Listerine Advanced Defence Sensitive; LADS) plus Colgate Cavity Protection Regular toothpaste, in reducing dentin sensitivity. METHODS: This was an observer- and examiner-blinded, randomized, parallel-group, single-center, controlled, five-day clinical trial. Healthy adults were randomized (2:1:1) to LADS plus Colgate Cavity Protection Regular toothpaste, or to one of the two negative-control toothpastes alone: Crest Cavity Protection Regular or Colgate Cavity Protection Regular. The subjects carried out supervised and unsupervised brushing and rinsing twice a day. Dentin sensitivity was assessed at baseline and during treatment by Yeaple probe (tactile pressure; patient-reported discomfort by visual analogue scale [VAS]), as well as response to air blasts (VAS). RESULTS: All sensitivity assessments were similar at baseline in the 56 randomized subjects. By the third day, the Yeaple probe sensitivity scores for subjects treated with Colgate toothpaste plus LADS improved significantly compared to Crest toothpaste alone (p < 0.05). By the fifth day, the mean scores for subjects treated with Colgate toothpaste plus LADS were significantly improved compared with subjects treated with either toothpaste alone (p < 0.05). The other sensitivity assessments showed that Colgate toothpaste plus LADS achieved statistically significant improvements compared with Colgate and/or Crest toothpaste alone from the third day. CONCLUSIONS: The 1.4% potassium oxalate mouthrinse (LADS) was associated with a reduction in dentinal sensitivity within a five-day period. Statistically significant reductions in all sensitivity variables were achieved by Day 3 and even greater reductions in dentin sensitivity scores were observed after five days.

PURPOSE: This randomized, examiner blind, parallel group, controlled clinical study evaluated the antiplaque and antigingivitis potential of an alcohol-free essential oils containing mouthrinse (Listerine Zero) compared to a 5% hydroalcohol mouthrinse (negative control), using a 2-week experimental gingivitis model. METHODS: 92 subjects, male and female, ranging in age from 18-68 years, in good general health, were assigned to one of the two treatment groups: Alcohol-free essential oils containing mouthrinse (LZ) or 5% hydroalcohol negative control (C) rinse. The mean Turesky Modification of the Quigley-Hein Plaque Index (PI) and the mean Modified Gingival Index (MGI) at 2 weeks were the primary efficacy endpoints. Following baseline examinations, subjects received a complete dental prophylaxis and began supervised rinsing with their assigned mouthrinse twice daily for 2 weeks, as their sole oral hygiene measure. RESULTS: 90 subjects completed the trial. At 2 weeks, LZ was more effective (P<0.001) than C in reducing plaque (23.9%) and gingivitis (10.4%).
