Abstract

Objective: This study was conducted to compare the effi cacy of chlorhexidine (0.2%) and sodium fl uoride (0.05%) mouthwashes in reduction of Streptococcus mutans count in plaque in seventy-fi ve children of age group 8-14 years. Methods: Children were equally divided in three groups. Group A and group B were test groups for chlorhexidine and sodium fl uoride respectively and group C was control group. The subjects were instructed to rinse the mouth with 10 ml of mouthwash for one minute twice daily for fi fteen days. Number of colony of Streptococcus mutans were counted by using mitis salivarius agar plate, at the beginning and at the end of the study period. Inter group and intra group comparisons were done to evaluate the effi cacies of mouthwashes by using paired t test and anova test. Results: There was signifi cant reduction in number of colony of Streptococcus mutans in both test groups. P value was found to be.000 in both whereas in control group, there was no signifi cant reduction in Streptococcus mutans (p=0.100) count. Among the two mouthwashes effi cacy of both were found to be statistically equal. Conclusions: The results of this study suggested that sodium fl uoride is a potent antimicrobial agent as chlorhexidine and would be better mouthwash due to its additional remineralization property for prevention of dental caries in children.
