Background: To determine the antimicrobial efficacy of 10% Povidone-iodine (PI) and Chlorhexidine (CHX) varnish against Streptococcus mutans and the role of antimicrobial therapy in the prevention of early childhood caries (ECC). Materials and Methods: A total of 30 children (3-6 years) with ECC reporting to the Department of Pedodontics, KVG Dental College and Hospital, Sullia for treatment were selected as a part of this study. The children were divided into two groups by block randomization. Following full mouth rehabilitation, one group had CHX varnish, Cervitec plus applied to their dentition and to the other group 0.2 ml of 10% PI was applied. Plaque and saliva samples were taken at baseline and at 30, 60, and 90 days following application of 10% PI and CHX varnish, and the presence of S. mutans was evaluated using Dentocult SM strip mutans. The results were evaluated using the manufacturer's chart. Results: There was a statistically significant reduction in the S. mutans count in plaque and saliva following application of 10% PI and CHX varnish for a period of 30, 60 and 90 days. The S. mutans count was <104 CFU/ml in both the groups at 30, 60 and 90 days. However, no significant difference in the efficacy of 10% PI and CHX varnish was observed. Conclusion: The results showed that there was a statistically significant reduction in the S. mutans count following application of 10% PI and CHX varnish for a period of 30, 60 and 90 days. No significant difference between the efficacy of 10% PI and CHX varnish was observed.
