Abstract

Introduction: Probiotics have been used to provide benefit to general health, but their effect on oral health especially on dental caries is yet to be explored in detail. Green tea is exclusively known for antioxidant and antimicrobial properties. Thus, the aim of the present study was to evaluate the anti-microbial efficacy of probiotic and green tea mouth rinse on salivary Streptococcus mutans count.

Methods: A triple-blinded, concurrent parallel group randomized trial was conducted which included 45 subjects, aged 21-25years. The subjects were randomly divided into three groups namely probiotic group, green tea group and chlorhexidine group. The participants were instructed to rinse their mouth once daily in the morning with the allocated mouth rinse. Unstimulated Saliva samples were collected at baseline, 30minutes post rinse and after 15 days of intervention. Microbial analysis was done to record Streptococcus mutans count.

Results: There was no statistically significant difference in reduction of microbial count of Streptococcus mutans between green tea and chlorhexidine mouth rinse after 15 days specifying both are equally effective in reducing S. Mutans count. However, probiotic group showed least antibacterial effect.

Conclusion: Green tea proved to be more effective in reducing Streptococcus mutans than probiotic mouth rinse. Also, the antibacterial effect of green tea was similar to that of chlorhexidine mouth rinse. Thus, green tea mouth rinse was found to be a successful alternate to chlorhexidine mouth rinse.
