Introduction: Dental caries and inflammatory periodontal diseases result from the accumulation of many different bacteria that form dental plaque, a naturally acquired bacterial biofilm that develops on the teeth. Periodontal diseases are one of the most prevalent oral diseases affecting more than 50% of Indian community. Materials and Method: A two months randomised controlled trial was conducted among ninety school children aged between 13 and 15 years, from a hostel located in Davangere city. The 90 study subjects who fulfilled inclusion and exclusion criteria were randomly divided into 3 groups namely Placebo, Chlorhexidine and Probiotic groups. Plaque scores were recorded at baseline (0 day), on 15 th day (after 14 days of intervention) and 3 weeks (after discontinuation of intervention). Statistical analysis was done using one way ANOVA and paired 't' test and P value less than 0.05 was considered statistically significant. Results: There was no statistically significant difference between groups at baseline. On 15 th day and after 3 weeks, plaque scores were significantly higher in placebo group compared to probiotic group. On 15 th day and after 3 weeks, plaque scores were higher in chlorhexidine group compared to probiotic group but difference was not statistically significant. Conclusion: Probiotic mouth rinse was more effective for inhibition of dental plaque accumulation after 14 days of intervention and also after 3 weeks of discontinuation of intervention.
