Approximately 0.1 mL of the designated varnish will be applied to all the teeth of subjects in all the three groups. Varnish was allowed to dry . The varnish was applied once every 3 days for all the three groups in the same manner as above. The follow-up plaque samples from all the three varnish groups was taken at the end of 48 h, at 1 m, at the end of 3 m and at the end of 6 m and assessed for bacterial counts .
Result: There was a statistically significant difference in the count of streptococcus mutans and lactobacillus between all groups in which the highest bacterial count was found in Group D group followed by Group A and Group B, while the least bacterial count was found in Group C .
