Abstract

Aim: To evaluate the effect of fluoride varnish on Streptococcus mutans count in saliva among 12-year-old school children. Materials and methods: A field experiment was conducted to evaluate the effects of fluoride varnish on S. mutans count in saliva among 12-year-old school children. A total of 42 school-going children attending schools in Vadodara district, Gujarat, India, were divided into two groups. Group I was treated with fluoride varnish and group II received no treatment. Assessment of S. mutans was carried out at baseline and 3 to 6 months postfluoride varnish application. Friedman analysis of variance test and post hoc test were applied to detect statistically significant differences between baseline, 3 to 6 months of fluoride varnish application, and also between groups I and II. Results: The mean number of salivary S. mutans value found in case group at baseline, 3 to 6 months was 31.23 ± 1.119, 9.27 ± 0.852, and 9.39 ± 0.908 × 104 colony-forming unit CFU/mL respectively. The difference in S. mutans count from baseline to 3 to 6 months was highly statistically significant (p = 0.000), but the difference from 3 to 6 months was not statistically significant (p = 0.142). In control group, the mean S. mutans value found at baseline, 3 to 6 months was 30.63 ± 1.436, 31.23 ± 1.351, and 31.40 ± 1.374 × 104 CFU/mL respectively. The differences between these values were not statistically significant (p = 0.11). Conclusion: Statistically significant reduction in S. mutans count in saliva was seen 3 to 6 months after fluoride varnish application.
