title: Effects of Fluoride Varnish onStreptococcus mutansCount in Saliva.
abstract: OBJECTIVE
  To evaluate the effect of fluoride varnish onStreptococcus mutanscount in saliva among 12-year-old school children.
  
  
  METHODS
  A field experiment was conducted to evaluate the effects of fluoride varnish on S.mutanscount 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.mutanswas carried out at baseline and 3 to 6 months postfluoride varnish application. Friedman analysis of variance test andpost hoctest 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.mutansvalue found in case group at baseline, 3 to 6 months was 31.23 ± 1.119, 9.27 ± 0.852, and 9.39 ± 0.908 × 104colony-forming unit CFU/mL respectively. The difference in S.mutanscount 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 meanS. mutansvalue found at baseline, 3 to 6 months was 30.63 ± 1.436, 31.23 ± 1.351, and 31.40 ± 1.374 × 104CFU/mL respectively. The differences between these values were not statistically significant (p = 0.11).
  
  
  CONCLUSIONS
  Statistically significant reduction in S.mutanscount in saliva was seen 3 to 6 months after fluoride varnish application.
