Aim: To evaluate and compare the efficacy of Ozonated Olive Oil Gel, Chlorhexidine gel, and Amflor (Fluoridated) mouthwash on reducing the count of Streptococcus mutans and Lactobacillus in patients undergoing fixed orthodontic therapy evaluated at different time intervals. Methods: Sixty patients undergoing orthodontic treatment were randomly divided into three groups (n = 20) based on antimicrobial agents used (Group 1: Ozonated olive oil gel; Group 2: Chlorhexidine gel; Group 3: Fluoridated mouthwash). Elastomeric modules from brackets were collected at T0 (Fresh samples) and T1 (2nd week) and T2 (4th week) for assessment of the microbial growth. These collected modules were cultured and evaluated for the presence of Streptococcus Mutans and Lactobacilli and numbers of colonies were counted at each interval. Data obtained was subjected to statistical analysis using SPSS software (Version 20.0). Level of significance was kept at 5%. Intra-group and inter-group comparison between pretreatment, 2nd week and 4th week was done for each group using Wilcoxon signed rank test and Mann–Whitney U test. Results: There was presence of Streptococcus Mutans and Lactobacilli during orthodontic treatment which progressively increased from To to T1 and then declined from T1 to T2. The colony counts were maximum for Fluoridated mouthwash and least for Chlorhexidine and the results were statistically significant (P < 0.05). Conclusion: All three antimicrobial agents used were effective against Streptococcus mutans and Lactobacillus. Chlorhexidine proved to be more efficacious whereas Fluoridated mouthwash proved to be least effective against both Streptococcus mutans and Lactobacillus bacteria.
