Abstract :The objective of this study was to investigate the effectiveness of ozone and mouth rinse on Streptococcus mutans (S.mutans) in pediatric patients with fixed orthodontic appliances. The study was conducted on 13-18 years old patients with fulfilled the inclusion criteria of high levels of S.mutans in saliva. Number of S. mutans in plaque and saliva was determined CFU/ml terms for baseline bacteriological counts. Patients were randomly divided into three groups: Group 1: Gaseous ozone, Group 2: Mouth Rinse, Group 3: Daily oral hygiene regime. Immediately after applications, stimulated saliva samples were collected again. After 1 week, plaque and saliva samples were recorded. Mann-Whitney U, Kruskal-Wallis and Wilcoxon T tests were used for statistical analysis. The reduced levels of S.mutans in saliva immediately after the application in the groups of Ozone and Listerine were found to be statistically significant (p<0,05). The Listerine group exhibited a significantly lower S.mutans counts in saliva compared with baseline and other groups after one week (p<0,05). After one week, the reduced level of S.mutans in plaque as compared to baseline values in all groups were found to be statistically significant (p<0,05). It can be concluded that the ozone treatment may have an instantaneous lethal effect on S.mutans ; however, a long-term preventive effect could not be observed. Listerine showed better effects on decreasing the level of S.mutans in saliva and plaque.
