Objectives : Dental caries is the most prevalent oral disease. Streptococcus mutans plays a major role in the occurrence of dental caries. Many antibacterial agents have been developed against dental caries. However, they lack the qualities of an ideal agent. Thus presently, antibacterial activity of herbal agents is being extensively studied. Materials and Methods: In the present study, ethanol extract of Terminalia chebula was prepared and mouthrinse was formulated. A total of 60 children meeting the inclusion criteria were randomly divided into study and control group and respective mouthrinses were administered. Salivary Streptococcus mutans count was assessed at 5 and 60 minutes after rinsing and compared with baseline values. Substantivity of the rinse was assessed among 10 children. Mouthrinse was given to the children and salivary Streptococcus mutans counts were assessed at baseline, 6 and 12 hours postrinsing. Mann-Whitney U test was used to assess the variance of factors like Decayed Missed Filled Teeth, plaque scores, and gingival scores. ANCOVA (Analysis of covariance) was used to determine the change in salivary Streptococcus mutans colony forming units taking baseline values as covariates. Results: It was observed that there was 44.42% reduction in salivary Streptococcus mutans colony forming units 5 minutes after rinsing as compared with baseline values and 64.14% reduction in Streptococcus mutans colony forming units at 60 minutes after rinsing as compared with baseline values. There was a reduction of 35.48% in salivary Streptococcus mutans colony forming units at 60 minutes after rinsing as compared with 5 minutes sample. Conclusion: Streptococcus mutans counts were low up to 6 hours postrinsing among 80% of the children.
