Abstract

Introduction: Probiotic concept of using beneficial bacteria has recently gained popularity in medical research. New methods such as probiotics has given a new dimension for both general and oral health. Objectives: This study aimed to investigate the efficacy of a Probiotic mouthrinse in reducing plaque and gingivitis among schoolchildren aged 15-16 years. Methods: This was a randomized, controlled, double blind clinical trial. 90 subjects granting their parental informed consent and willing to participate completed the trial. The sample was randomized by computer generated table into Group A #x2013;0.2% of chlorhexidine mouthrinse, Group B #x2013; Probiotic mouthrinse, Group C #x2013; Placebo mouthrinse. Products were masked as regards color. Intervention protocol consisted in supervised rinsing of 20 mL/day for 60 seconds twice daily for 14 days. Plaque and gingival indexes were used to assess the efficacy variables, measured at baseline and after intervention by calibrated examiner. Data were statistically analysed. Results: It was found that both Probiotic and chlorhexidine mouthrinses were able to significantly reduce plaque and gingival levels after 14 days (plt;0.05). Conclusion: probiotic mouthrinse showed significant reduction in plaque score and gingival level.
