Aim The aim of the study was to assess and compare the effect of chlorhexidine varnish and fluoride varnish application on S treptococcus mutans counts in plaque of occlusal pits and fissures of permanent mandibular first molars. Materials and methods The study was an in vivo comparative study, conducted among 50 schoolchildren aged 7–8 years under a field setting. The 50 subjects were randomly allocated into two groups. Baseline plaque samples were collected from all the subjects followed by the application of two varnishes, C ervitec and D uraphat. The varnish was applied to pit and fissures of occlusal surface of mandibular first molar. The varnish application was carried out on the first day, fifth day and tenth day after baseline plaque sampling. Subsequent plaque samples were collected at the end of 1 month and at the end of 3 months after the varnish application. Results The C ervitec varnish has shown a statistically significant reduction at the end of 1 month and at the end of 3 months ( P < 0.05). Duraphat varnish did not show a statistically significant difference in reducing the plaque S. mutans count at the end of 1 month and third month ( P > 0.05). Conclusion Cervitec varnish was found to be effective in reducing S . mutans count for a 3‐month period, when compared to D uraphat varnish.
