Introduction: Orthodontic treatment facilitates the growth of pathogens and leads to white spot lesions and caries formation. This study was carried out to compare the efficacy of probiotics, prebiotics, and symbiotics on the salivary levels of Streptococcus mutans, Lactobacillus, and Bifidobacterium. Materials and Methods: Saliva samples were collected from the patients who were undergoing comprehensive orthodontic treatment at two different time intervals, baseline (T0) and postintervention (T1) that is 1 month after administration of prebiotic, probiotic, and symbiotic bacteria, respectively, for Groups A, B, and C; placebo was included in Group D. Samples were inoculated on selective media, after incubation growth was identified. Colony counts were recorded in colony forming units per milliliter. Paired t-test, analysis of variance, and post hoc Tukey's honest significant difference test were used for analysis, and P < 0.05 was considered to be statistically significant. Results: Among the participants, S.mutans counts were found to be decreased (P < 0.05) and lactobacilli and bifidobacterium counts were found to be increased (P > 0.05). Conclusion: Short-term consumption of probiotics, prebiotics, and symbiotics had effectively reduced the S. mutans levels in the oral cavity with increased levels of Lactobacillus and Bifidobacterium when compared with the placebo group.
