Effectiveness of Herbal, Homeopathic and Conventional Dentifrices on Dental Caries - A Double-Blind Randomised Controlled Trial.

PURPOSE: To compare the effectiveness of ayurvedic, homeopathic and conventional dentifrices on plaque and saliva in terms of cariogenic bacteria, salivary pH, and plaque pH. MATERIALS AND METHODS: This double-blinded, parallel-group, randomised controlled trial was performed at Saveetha Dental College and Hospitals, Chennai, India. The participants comprised healthy adults possessing more than 20 permanent natural teeth and having a Decayed Missing and Filled Teeth (DMFT) score, plaque index score, and gingival index score less than or equal to 2. There were 3 intervention groups: 1: herbal dentifrice (Dabur Meswak); 2: homeopathic dentifrice (Gum Forte gel); 3: fluoride dentifrice (Colgate Total). The outcome measures were as follows: plaque and saliva samples were evaluated for pH; colony counts of Streptococcus mutans and Lactobacillus at baseline, 14 and 28 days of follow-up. One-way and repeated measures ANOVA, Wilcoxon signed-rank and Kruskal Wallis tests were used to compare the mean differences of plaque and salivary pH and plaque and salivary S. mutans and Lactobacillus counts at baseline, 14 and 28 days. RESULTS: The mean S. mutans and Lactobacillus counts in plaque and saliva decreased statistically significantly in all treatment groups at the 28-day follow-up. Mean plaque pH was not statistically significantly different at the 14-day follow-up (p-value = 0.16). On the 28th day, group 1 (7.64 ± 0.20) showed the highest increase in plaque pH followed by group 2 (7.39 ± 0.25) and group 3 (7.27 ± 0.19), which was found to be statistically significant. No statistically significant difference in mean salivary pH was observed between the three groups at the different time points. CONCLUSION: This study reveals that the herbal dentifrice tested here was effective in reducing cariogenic bacterial count and increasing the plaque pH, thereby warranting the usage of the same.

Evaluation of the efficacy of plaque reduction and gingival health among 6-12 years old school children before and after a short term daily intake of probiotic lozenge - A comparative study.

Context: Probiotics are defined as live microorganisms which when delivered in adequate amounts provides health benefit in the host. Dietary supplements like lozenge seem to be the easy and acceptable vehicle for ingestion of probiotics in young children. Aim: To assess the efficacy of probiotics in plaque reduction and gingival health among 6-12 years school children before and after short term daily intake of Probiotic lozenge. Settings and Design: This Comparative study was conducted among 60 children in the age group 6-12 years. Thirty children in experimental group; who were given lozenge containing probiotic bacteria twice daily, one in the morning and another in the evening after brushing for one month. The placebo lozenge group also followed the same protocol. Statistical Analysis Used: SPSS version 21. Results: The Probiotic lozenge group was found to have statistically significant reduction in plaque scores when compared to that of the placebo group with P < 0.001 and there was also a significant improvement in gingival health. Conclusion: An effective reduction in plaque accumulation and gingival inflammation was found with the use of probiotic lozenges and hence proved the therapeutic value of the same.

Comparative effectiveness of herbal and conventional toothpaste on prevention of dental caries: systematic review and meta-analysis.

Dental caries is a global oral health problem caused due to localized demineralization of the enamel. Chemical plaque control is used as an adjuvant to mechanical plaque control in removing biofilm, thereby preventing dental caries. In recent times, there has been a renewed interest in nature-based products. This systematic review aimed to analyse the existing literature to compare the effectiveness of herbal and conventional dentifrices on prevention of dental caries. A search was done in the databases of PubMed and Google Scholar in July 2020 for the related topic. A hand search was done from the references of primary studies and other clinical trial registry sites. Randomized control trials, comparative clinical trials, and in vitro studies in which the effectiveness of herbal and conventional dentifrices on prevention of dental caries were included after review by the reviewers. The systematic search revealed a total of thirty-two publications from which ten publications were included. Five studies were clinical studies and five were in vitro studies. All the studies used microbiological analysis for the determination of cariogenic microorganisms in plaque and saliva, whereas one study used pH of plaque and saliva. Among the included studies, all studies had a high risk of bias with level 2 evidence. With the evidence available, it can be concluded that herbal dentifrices and fluoride dentifrices have similar antimicrobial activity against cariogenic microorganisms.

Efficacy of marine algal extracts against oral pathogens - A systematic review.

Introduction: Marine algae possess a plethora of secondary active metabolites which has many biomedical applications. Anti-bacterial activity against oral cariogenic bacteria is reported in literature, however there is no comprehensive review available. Hence, this review is attempted to collate all the evidence available regarding the marine algal extracts and its constituents against oral cariogenic bacteria. Methods: Electronic search was conducted in the Google scholar, the Pubmed database and various clinical trial registries. Included studies were clinical, in-vitro studies assessing DMFT, DMFS, minimum inhibitory concentration or colony forming unit counts. Result: A total of 19 trials were obtained out of which only 7 were eligible for this review. Quality assessment was done by Higgins and Greens (2011) method. Results showed all the studies where they used crude algal extracts or its active constituents were showing anti-bacterial activity. Conclusion: Thus, this review showed that marine algal extracts and other constituents are having anti-microbial properties, making them potential anti-microbial agents for oral hygiene maintenance without adverse effects of currently available chemical based oral care products.
