Comparison of the plaque regrowth inhibition effects of oil pulling therapy with sesame oil or coconut oil using 4-day plaque regrowth study model: A randomized crossover clinical trial.

OBJECTIVES: The aim of this study was to compare the plaque-inhibiting effects of oil pulling therapy with sesame oil or coconut oil using 4-day plaque regrowth study model. METHODS: This clinical observer-masked, randomized, crossover designed study involved 24 participants. The participants received professional prophylaxis in the preparatory period and after that subjects started to use the allocated mouthrinse (coconut oil or sesame oil). On day 5, periodontal clinical parameters including plaque index (PI), gingival index (GI), stain index (SI) and bleeding on probing (BOP) were recorded. Subjects underwent a 14-day wash out period and then used the other mouthrinse for 4 days. RESULTS: Oil pulling therapy with coconut oil or sesame oil exhibited similar plaque regrowth inhibition (PI = 1.60 ± 0.28 and 1.49 ± 0.22, for oil pulling with coconut oil and sesame oil, respectively) and tooth staining (SI = 0.20 ± 0.11 and 0.21 ± 0.09, for oil pulling with coconut oil and sesame oil, respectively.) In addition, GI and BOP were similar in both groups (GI = 0.61 ± 0.19 and 0.69 ± 0.16; BOP = 0.09 ± 0.24 and 0.03 ± 0.03 for oil pulling with coconut oil and sesame oil, respectively). CONCLUSIONS: Oil pulling therapy with coconut or sesame oil showed similar results in terms of plaque regrowth inhibition and tooth staining. According to the present results, both coconut oil and sesame oil can be used for oil pulling therapy with the aim of plaque regrowth inhibition.

Antimicrobial Efficacy of Herbal and Chlorhexidine Mouthrinse against Staphylococcus aureus - An in vitro Microbiological Study.

Background: Microorganisms in the oral cavity are still considered serious public health problems and position a costly burden on health-care services worldwide and elsewhere. Mouthrinses have been used in the oral cavity for decades with the intention of reducing the amount of microorganisms. Mouthrinses are used as additives to oral mechanical hygiene. Therapeutic mouthwashes are also prescribed as an alternative to mechanical plaque control for plaque accumulation prevention and for gingival and peri-implant health maintenance. Mechanical control alone has been questioned to eliminate recalcitrant biofilms in the oral cavity because it is known to be very time-consuming and, most significantly, inadequate for good oral hygiene. The aim of this study was to assess the minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and antimicrobial efficacy of herbal and chlorhexidine (CHX) mouthrinse against Staphylococcus aureus. Materials and Methods: For MIC (macrobroth dilution method), MBC and antimicrobial effectiveness (zone of inhibition) of an herbal mouthrinse and 0.2% CHX mouthrinse were determined by the agar well diffusion method. Results: The zone of inhibition of S. aureus was 24 mm for the CHX mouthrinse. The arowash liquid mouthrinse shows that S. aureus does not produce a zone of inhibition. Conclusion: CHX mouthrinse (0.2%) has a better antimicrobial efficacy against the S. mutans when compared to herbal mouthrinse (arowash liquid).

Effect of herbal mouthrinses on dental plaque formation and gingival inflammation: A systematic review.

To evaluate the effect of herbal mouthrinses as an adjuvant to oral hygiene on dental plaque and gingival inflammation in subjects with gingivitis. Searches were conducted in the PubMed/MEDLINE, Cochrane-CENTRAL, EMBASE, Web of Science, LILACS/BIREME, Clinical Trials Registry and grey literature for Randomised Clinical Trials (RCTs) published up to April 2018 without language restrictions. From 4,013 paper found, 20 studies met the eligibility criteria and were included. The herbal mouthrinses achieved significant reductions in dental plaque and gingival inflammation compared to placebo rinses. Five herbal products (Camelia sinensis, Azadirachta indica, Anacardium occidentale Linn, Schinus terebinthifolius and Curcuma longa) showed better results than chlorhexidine in dental plaque and gingival inflammation reductions. However, the unclear risk of bias of most included RCTs precludes definitive conclusions. Therefore, it is necessary to improve the design of future RCT in other reduced potential bias that may affect the degree of precision of treatment outcomes in order to evaluate the effect size and clinical relevance of herbal mouthrinses.

Comparison of Punica granatum, Terminalia chebula, and Vitis vinifera Seed Extracts used as Mouthrinse on Salivary Streptococcus mutans Levels in Children.

AIM: The present study was conducted to compare the efficacy of all Punica granatum, Terminalia chebula, and Vitis vinifera on salivary Streptococcus mutans levels in children and also to evaluate their substantivity at an interval of 15 days that is at day 1, days 16, and 31. MATERIALS AND METHODS: This study was designed for a randomized clinical double-blinded study where 80 children of 8-15 years of age were living in a residential premise. Subjects were randomly divided into 4 groups of 20 each to whom mouthrinses were given. The criteria for assessing the efficacy was done by collecting the saliva sample for pH, buffering capacity, plaque index, and Streptococcus mutans microbiologic assay. These values were assessed at the baseline, days 16, and 31. Children were asked to discontinue mouthrinse from days 16 to 31. The supervisor was trained to administer the mouthrinses properly. RESULTS: The data were coded and analysis was done using the SPSS version 20. The level of significance was set at p < 0.05. The pH and buffering capacity showed that values were almost the same among all four groups at various time intervals which showed statistically nonsignificant results. Punica granatum showed a maximum reduction in S. mutans count followed by T. chebula and V. vinifera, although they were statistically nonsignificant. The Vitis vinifera group had successfully reduced more plaque score at day 16 (0.04) followed by T. chebula (0.09) and P. granatum (0.12). CONCLUSION: This in vivo study implied that V. vinifera had shown the lowest plaque reduction owing to its antioxidant and phytochemical properties. And P. granatum showed the maximum substantivity. CLINICAL SIGNIFICANCE: Mouthrinses helped in reducing plaque deposition, caries activity, and helped in oral hygiene maintenance. Hereby, we can conclude that nutraceutical mouthrinses are safe in children and produced superior results than the chemical mouthrinses.

Efficacy of oil pulling therapy with coconut oil on four-day supragingival plaque growth: A randomized crossover clinical trial.

OBJECTIVES: The aim of this study was to evaluate the plaque-inhibiting effects of oil pulling using 4- day plaque regrowth study model compared to 0.2% chlorhexidine gluconate (CHX) containing mouthrinse. DESIGN: The study was an observer-masked, randomized, cross-over design clinical trial, involving 29 volunteers to compare 0.2% CHX and oil pulling therapy in a 4- day plaque regrowth model. After the preparatory period, in which the subjects received professional prophylaxis, the subjects commenced rinsing with their allocated rinsed. On day 5 plaque index (PI), gingival index (GI), stain index (SI), bleeding on probing (BOP) were recorded from the subjects. Each participant underwent a 14- day wash out period and then used the other mouthrinse for four days. RESULTS: Oil pulling therapy presented similar inhibitory activity on plaque regrowth compared with CHX (PI = 1.67 ±â€¯0.24, 1.61 ±â€¯0.20, respectively) with less staining (SI = 0.21 ±â€¯0.13, 0.47 ±â€¯0.27, respectively). In addition, GI and BOP was similar in both groups (p > 0.05). CONCLUSION: Oil pulling with coconut oil seems to have similar plaque inhibition activity as CHX. In addition it caused less tooth staining than CHX. These findings suggest that oil pulling therapy may be an alternative to CHX rinse.

Effect of Herbal Water, Ozonated Water, Water, and Chlorhexidine Mouthrinses on Oral Health Status of Children: A Randomized Controlled Trial.

AIM: To evaluate the antibacterial effect of herbal water, ozonated water, and chlorhexidine mouthrinses on salivary Streptococcus mutans level and to assess their effectiveness of these mouthrinses on the oral health status of children. MATERIALS AND METHODS: A parallel multiarm randomized controlled trial was conducted in 100 children aged 10-12 years. Debris index-simplified (DI-S), calculus index-simplified (CI-S), oral hygiene index-simplified (OHI-S) scores, and Streptococcus mutans counts were recorded at baseline (T 1). They were randomly divided into four equal groups (n = 25): HW, herbal water; OW, ozonated water; W, water; and CHX, chlorhexidine. Intervention period was 15 days and data collection was repeated after 15 days (T 2) and 30 days (T 3). Saliva samples were used to evaluate S. mutans count. Results were tabulated and analyzed statistically. RESULTS: OW had minimum DI-S score at T 2 and T 3 periods. HW had the minimum CI-S score at T 2 and T 3 periods. CHX had the minimum S. mutans count at T 2 and T 3 periods. OW showed maximum reduction in OHI-S score at T 2 period. HW showed maximum reduction in OHI-S score at T 3 period. CONCLUSION: Herbal water and ozone water can be used as an alternative to chlorhexidine in maintaining the oral health status. CLINICAL SIGNIFICANCE: Herbal water and ozonated water can be used in children instead of chemical mouthrinses to avoid any adverse effects.

The effects of essential oil mouthrinses with or without alcohol on plaque and gingivitis: a randomized controlled clinical study.

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 .

Effectiveness of Azadirachta indica (neem) mouthrinse in plaque and gingivitis control: a systematic review.

OBJECTIVES: The aim of this systematic review was to evaluate the effectiveness of Azadirachta indica (neem)-based herbal mouthrinse in improving plaque control and gingival health. METHODS: Literature search was accomplished using electronic databases (PubMed, Cochrane Central Register of Controlled Trials and EMBASE) and manual searching, up to February 2015, for randomized controlled trials (RCTs) presenting clinical data for efficacy of neem mouthrinses when used alone or as an adjunct to mechanical oral hygiene as compared to chlorhexidine mouthrinses for controlling plaque and gingival inflammation in patients with gingivitis. RESULTS: Of the total 206 articles searched, three randomized controlled trials evaluating neem-based herbal mouthrinses were included. Due to marked heterogeneity observed in study characteristics, meta-analysis was not performed. These studies reported that neem mouthrinse was as effective as chlorhexidine mouthrinse when used as an adjunct to toothbrushing in reducing plaque and gingival inflammation in gingivitis patients. However, the quality of reporting and evidence along with methods of studies was generally flawed with unclear risk of bias. CONCLUSION: Despite the promising results shown in existing randomized controlled trials, the evidence concerning the clinical use of neem mouthrinses is lacking and needs further reinforcement with high-quality randomized controlled trials based on the reporting guidelines of herbal CONSORT statement.

Efficacy of two mouthwashes on 3-day supragingival plaque regrowth: a randomized crossover clinical trial.

BACKGROUND: The aim of this study was to evaluate the antiplaque effects of an alcohol-free essential oil (alcohol-free EO) mouthwash and an amine fluoride/stannous fluoride with zinc lactate (SnFl-Zn) mouthwash compared to a positive control of chlorhexidine (CHX) mouthwash, using an in vivo plaque regrowth model of 3 days. MATERIALS AND METHODS: The study was designed as a double-masked, randomized, crossover clinical trial, involving 20 volunteers to compare two different mouthwashes, using a 3-day plaque accumulation model. After receiving thorough professional prophylaxis at baseline, over the next 3 days, each volunteer refrained from all oral hygiene measures and performed two daily rinses with 20 ml of the test mouthwashes. A 0.20% CHX rinse served as a positive control. At the end of each experimental period, plaque was assessed, and the panellists completed a questionnaire. Each subject underwent a 14-day washout period, and then, there was another allocation. RESULTS: The SnFl-Zn mouthwash has shown a better inhibitory activity on plaque regrowth compared to the alcohol-free EO mouthwash in the whole mouth (plaque index = 1.93 against 2.45, respectively), but there was less of an effect compared to the CHX group, with an overall plaque index of 1.41. The differences of 0.52 between alcohol-free EO and SnFl-Zn and between SnFl-Zn and CHX and of 0.96 between alcohol-free EO and CHX were all statistically significant (P < 0.001). CONCLUSION: The alcohol-free EO mouthwash seemed to have less of an inhibiting effect on plaque regrowth than the amine fluoride/SnFl-Zn mouthwash and the CHX control.

Mouthwashes in the 21st century: a narrative review about active molecules and effectiveness on the periodontal outcomes.

INTRODUCTION: Poor oral hygiene is a major risk factor for oral diseases. Regular home-based care is essential to maintain good oral hygiene. In particular, mouthrinses can support conventional tooth brushing in reducing accumulation of oral plaque. Areas covered: The most common molecules contained in mouthrinses (chlorhexidine, essential oils, cetyl pyridinium chloride, triclosan, octeneidine, delmopinol, polyvinylpyrrolidone, hyaluronic acid, natural compounds) are discussed, together with relevant clinical and in vitro studies, focusing on their effects on periodontal health. Currently, chlorhexidine is the most efficacious compound, with both antiplaque and antibacterial activities. Similar results are reported for essential oils and cetyl pyridinium chloride, although with a somewhat reduced efficacy. Considering the adverse effects of chlorhexidine and its time-related characteristics, this molecule may best be indicated for acute/short-term use, while essential oils and cetyl pyridinium chloride may be appropriate for long-term, maintenance treatment. Expert opinion: The literature has not clearly demonstrated which compound is the best for mouthrinses that combine good efficacy and acceptable side effects. Research should focus on substances with progressive antibacterial activity, prompting a gradual change in the composition of oral biofilm and mouthrinses that combine two or more molecules acting synergistically in the mouth.

Comparative effects of aqueous single-phase and oil-water two-phase mouthrinses containing bamboo salt, magnolia bark and Centella asiatica extracts on reducing gingivitis: a randomized clinical trial / 대한구강보건학회지

OBJECTIVES: The aim of this study was to assess the antiplaque and antigingivitis effectiveness of aqueous single-phase and oil-water two-phase mouthrinses, containing bamboo salt, magnolia bark, and Centella asiatica extracts, in Korean adults. METHODS: In this double-blinded clinical trial, a total of thirty-four participants aged over 19 years were randomly allocated to three experimental groups: 1) control group; 2) aqueous single-phase mouthrinse (ASM) group, and; 3) oil-water two-phase mouthrinse (OTM) group. The experimental mouthrinses all contained sodium fluoride, and the ASM and OTM contained additional ingredients of bamboo salt, magnolia bark, and Centella asiatica extracts. For the OTM, 50% essential oil was added to create an oil-water two-phase mouthrinse. A two-week randomized crossover design with a two-week washout period was applied. Following a complete dental prophylaxis, participants were instructed to use the prescribed mouthrinse twice daily for two weeks as an adjunct to their usual mechanical oral hygiene procedures. Pre- and post-experiment clinical examinations were performed to measure the plaque index (PI) and bleeding on probing (BOP) for the full mouth. Paired t-test was applied to compare the intergroup differences for all clinical variables. RESULTS: Compared to the control group, ASM showed a significantly reduced BOP (P<0.05). However, there was no statistically significant difference in the effects of the three mouthrinses on reducing the PI. CONCLUSIONS: The results of this study indicate that the use of an aqueous, single-phase mouthrinse containing bamboo salt, magnolia bark and Centella asiatica extracts could help alleviate gingivitis.

In vitro Effect of Mouthrinse Containing Essential Oils on Proliferation and Migration of Gingival Epithelial Cells.

We aimed to investigate in vitro the effects of mouthrinses containing essential oils (EOs) on proliferation and migration of gingival epithelial cells. Human gingival epithelial cells were treated with predetermined dilutions of commercially available EO mouthrinses with or without ethanol and a mouthrinse containing cetyl pyridinium chloride (CPC) for 60 s. Cell proliferation was evaluated using WST-1 assay. Cell migration was assessed using a wound closure model. Within 10 s of exposure to EO mouthrinse without ethanol, the epithelial cells became aberrant and shrank. No statistically significant difference in cell migration or proliferation was observed among cells pretreated by the EO mouthrinse with ethanol, CPC mouthrinse and control (phosphate buffered saline). In contrast, the EO mouthrinse without ethanol significantly reduced cell proliferation (p < 0.001) to approximately 20% relative to control. As for the EO mouthrinse without ethanol, it was not possible to assess its effect on cell migration using this model, because treated cells could be easily detached from the culture plate upon scratch, possibly because of the surfactant ingredient in the formulation. Within the limitations of the study, the EO mouthrinse with ethanol exerted no inhibitory effect on proliferation and migration of the gingival epithelial cells.

Short-term evaluation of a green tea extract-based mouthrinse / Avaliação de curto prazo de um enxaguatório bucal à base de extrato de chá verde

Introduction: mechanical hygiene is still the best method forthe maintenance of oral health and prevention of biofilm formation. However, mouthrinses have been increasingly used as an adjunct support especially for post-operatory conditions or when periodontal conditions require. In this way, a number of mouthrinses are available, presenting different active ingredients with predominant antimicrobial action. Objectives: the aim of the present study was to evaluate the topical action of a green-tea extract-based mouthwash on gingival tissue. Materials and Methods: a longitudinal double-blind comparison was performed with two groups of patients clinically evaluated and diagnosed as suffering from gingivitis (n= 40). The patients were divided into two groups, according to the mouthrinse used: GT - green tea (concentration of 20mg/ml), and P - placebo, 0.9% saline solution. Clinical examination of the mucosa, tooth staining, plaque and gingival indices were peformed before and 15 days after the continuous use of the products twice a day. Results: no mucosal or tasting alterations were found, neither tooth staining regardless the mouthrinse used. Statistical assessment did not detect differences on gingival indexes between the groups before and after mouthrinses use; however, plaque indexes were significant lower in patients of GT group, compared to the P group. Conclusions: the use of phytotherapic products with active ingredients should be investigated for biofilm control, responsible for the onset and progression of periodontal disease, as well as other various oral pathologies. Considering the period of evaluation pro-posed in this study, relevant decrease in initial phase of plaque for-mation could be observed with the green tea mouthrinse. Further long-term evaluation studies should be carried-out in order to eluci-date its continuous effects on oral structures.

Introdução: higiene mecânica ainda é o melhor método para a manutenção da saúde bucal e prevenção da formação de biofilmes. No entanto, enxagues têm sido cada vez mais usado como um suporte auxiliar especialmente para as condições pós-operatórias ou quando as condições periodontais exigem. Desta forma, um número de bochechos estão disponíveis, apresentando diferentes ingredientes ativos com predominante ação antimicrobiana. Objetivos: o objetivo do presente estudo foi avaliar a ação tópica de um bochecho à base de extrato de chá verde no tecido gengival. Materiais e Métodos: a comparação longitudinal, duplo-cego, foi realizada com dois grupos de pacientes clinicamente avaliados e diagnosticados como portadores de gengivite (n = 40). Os pacientes foram divididos em dois grupos, de acordo com o enxaguatório oral usado: CV - chá verde (concentração de 20 mg / ml), e P - placebo, solução salina a 0,9%. O exame clínico da mucosa, coloração dos dentes, índice de placa e índice gengival foram realizados antes e 15 dias após o uso contínuo dos produtos duas vezes por dia. Resultados: nenhuma alteração na mucosa ou de degustação foi encontrada, assim como não foi identificado modificação na coloração do dente. A Avaliação estatística não detectou diferenças no índice gengival entre os grupos antes e depois de usar enxaguatórios. No entanto, índice de placa inferior foi menor de forma significativa nos pacientes do grupo CV, em comparação com o grupo P. Conclusões: o uso de produtos fitoterápicos com ingredientes ativos deve ser investigado para o controle de biofilme, responsável pelo aparecimento e progressão da doença periodontal. Considerando o período de avaliação proposto, a redução correspondente na fase inicial da formação de placa pôde ser observada com o enxaguatório à base de chá verde. Além disso, estudos de avaliação de longo prazo devem ser realizados, a fim de elucidar seu efeito contínuo em longo prazo sobre as estruturas orais.

Can Chemical Mouthwash Agents Achieve Plaque/Gingivitis Control?

Also note that structured abstracts are not allowed per journal style: What is the effect of a mouthwash containing various active chemical ingredients on plaque control and managing gingivitis in adults based on evidence gathered from existing systematic reviews? The summarized evidence suggests that mouthwashes containing chlorhexidine(CHX) and essential oils (EO) had a large effect supported by a strong body of evidence. Also there was strong evidence for a moderate effect of cetylpyridinium chloride(CPC). Evidence suggests that a CHX mouthwash is the first choice, the most reliable alternative is EO. No difference between CHX and EO with respect to gingivitis was observed.

Meta-analysis of the effect of an essential oil-containing mouthrinse on gingivitis and plaque.

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).

Antimicrobial effect of lemongrass oil against oral malodour micro-organisms and the pilot study of safety and efficacy of lemongrass mouthrinse on oral malodour.

AIMS: Lemongrass oil (LG) has been reported as being effective against bacteria embedded within the biofilm. The aims of this study were to investigate antimicrobial activity against common odourigenic micro-organisms, the safety and efficacy of LG mouthrinse on oral malodour in healthy volunteers. METHODS AND RESULTS: Antimicrobial activity of LG mouthrinse was examined against common odourigenic micro-organisms using broth microdilution assay and the disc diffusion method. A randomised double-blind clinical study was performed in 20 healthy volunteers. Volatile sulphur compounds (VSCs) level was measured using a Halimeter on day 0 and day 8 in each volunteer. The results showed that LG mouthrinse was effective against Aggregatibacter actinomycetemcomitans ATCC43718 and Porphyromonas gingivalis W50 but less effective against Streptococcus mutans ATCC 25175. In addition, the mouthrinse significantly reduced VSCs on day 8. CONCLUSIONS: LG mouthrinse was able to reduce oral malodour and appeared to be safe. The overall satisfaction of the mouthrinse was acceptable. However, the spiciness and taste of the mouthrinse need to be improved. SIGNIFICANCE AND IMPACT OF THE STUDY: This study demonstrated that the LG mouthrinse significantly reduced oral malodour. This mouthrinse would be another alternative mouthrinse choice for prevention of malodour, plaque and gingivitis.

Early benefits with daily rinsing on gingival health improvements with an essential oil mouthrinse--post-hoc analysis of 5 clinical trials.

PURPOSE: The aim of this investigation through post-hoc analyses was to determine the ability to achieve gingival health in the short term with daily rinsing with an essential oil containing antimicrobial mouthrinse. METHODS: Conventional Analysis of Covariance (ANCOVA) on whole mouth mean plaque and gingivitis scores were originally conducted to demonstrate efficacy of adjunctive use of Cool Mint® LISTERINE® Antiseptic (EO) compared to negative control [brushing (B) or brushing/flossing (BF)] in each of 5 studies containing a 4 week evaluation. The Modified Gingival Index (MGI) was split into 2 categories: healthy (scores 0, 1) and unhealthy (≥2). Data, reflecting subjects that completed 4 weeks of treatment from 5 studies, were evaluated to determine the mean percent of healthy sites and mean percent of more inflamed "affected" areas (MGI≥3). RESULTS: At baseline, the mean percent healthy gingival sites ranged from 0.1 to 3.2%. At 4 weeks, up to 29.3% and 16.1% of sites were healthy for the EO group and negative control group, respectively. Three and 6 month data from 2 of the 5 studies resulted in up to 39.6% and 62% at 3 and 6 month mean percent healthy sites per subject for EO and up to 17.2% and 15.6% at 3 and 6 months, respectively, for negative control. Virtually plaque free sites (PI=0, 1) at 4 weeks ranged up to 34.3% and 8.1% for EO and control groups, respectively. CONCLUSION: Significantly more healthy gingival sites and virtually plaque free tooth surfaces can be achieved as early as 4 weeks with use of an essential oil antimicrobial mouthrinse. This finding continues through 6 months twice daily use as part of oral care practices compared to mechanical oral hygiene alone.

A comparative study of antiplaque and antigingivitis effects of herbal mouthrinse containing tea tree oil, clove, and basil with commercially available essential oil mouthrinse.

BACKGROUND: The relatively safe nature and cost-effectiveness of herbal extracts have led to a resurgent interest in their utility as therapeutic agents. Therefore, this prospective, double-blind, randomly controlled clinical trial was designed to compare the antiplaque and antigingivitis effects of newly formulated mouthrinse containing tea tree oil (TTO), clove, and basil with those of commercially available essential oil (EO) mouthrinse. MATERIALS AND METHODS: Forty patients were selected for a 21-day study period and randomly divided into two groups. The test group patients were given newly formulated herbal mouthrinse and the control group patients were given commercially available EO mouthrinse. The Plaque Index (PI), Gingival Index (GI), and Papillary Marginal Attachment (PMA) Index were recorded at baseline, 14 days, and 21 days. The microbial colony forming units (CFU) were assessed at baseline and 21 days. RESULTS: Test group patients using herbal mouthrinse showed significant improvement in GI (0.16), PI (0.57), and PMA (0.02) scores. These improvements were comparable to those achieved with commercially available EO mouthrinse. However, the aerobic and anaerobic CFU of microbiota were reduced with the herbal mouthrinse (P = 0.0000). CONCLUSION: The newly formulated herbal mouthrinse and commercially available mouthrinse were beneficial clinically as antiplaque and antigingivitis agents. Newly formulated mouthrinses showed significant reduction in microbial CFU at 21 days. So, our findings support the regular use of herbal mouthrinse as an antiplaque, antigingivitis, and antimicrobial rinse for better efficacy.

The effect of an essential-oils mouthrinse as compared to a vehicle solution on plaque and gingival inflammation: a systematic review and meta-analysis.

OBJECTIVE: The purpose of this review was to systematically evaluate the effects of an alcohol vehicle solution (V-Sol) compared with an essential-oils mouthwash (EOMW) and if available with a water-based control (WC) on plaque, gingival inflammation parameters and extrinsic tooth staining. MATERIALS AND METHODS: The PubMed-MEDLINE, Cochrane-CENTRAL and EMBASE databases were searched. Where appropriate, a meta-analysis was performed, and difference of means (DIFFM) as calculated. RESULTS: In total, 971 unique papers were found of which five met the eligibility criteria. The DIFFM of the meta-analysis of four 6-month studies showed that the EOMW provided significantly better plaque control (DIFFM = 0.39, P < 0.00001) and gingival inflammation reduction as measured by the Löe and Silness Index (DIFFM = 0.36, P = 0.00001) as compared to the V-Sol. Regarding extrinsic tooth staining, a small but significant difference (DIFFM = -0.08, P = 0.03) was observed. CONCLUSION: Limited data, but with a low risk of bias, were available to assess the potential benefit of the alcohol-containing V-Sol. 'High'- and 'moderate'-quality data were available for the analysis of plaque and gingivitis, respectively. Within these limitations, EOMW appears to provide a significant oral health benefit during the 6 months of use. The data retrieved for this review suggest that the essential oils produce an effect on plaque and gingivitis that extends beyond the V-Sol. Furthermore, the V-Sol proved to be no different from a WC.
