Introduction Dental caries is still epidemic and a significant public health problem in developing countries. No research on a fluoride mouth rinsing program has been conducted in Sri Lanka yet. Therefore, the purpose of this study was to evaluate the effectiveness of a supervised school-based 0.2% sodium fluoride mouth rinsing program among 6 year-old Sri Lanka school children.
Material and Methods This study was conducted on 415 school children from the Yatinuwara educational zone of the Kandy district, Sri Lanka from January 2011 to January 2014. The children were allocated into two groups by adjusting their socio-demographic background and the fluoride level in drinking water at school level; Group 1 received 0.2% sodium fluoride mouth rinses weekly, and Group 2 was the control group. A clinical oral examination and oral health education were performed at baseline and annual follow-ups.
Results At the baseline, the mean age of school children in the intervention group and the control group were 6.17 ± 0.41 years and 6.08 ± 0.50 years, respectively. Almost all of the children (>90%) used fluoride toothpaste in both groups. After the fluoride mouth rinsing program, the intervention group (77.8%) showed higher caries free proportion than the control group (63.1%), although no statistically significant difference occurred. The mean DMFT and DMFS indices in the intervention group were significantly lower than those in the control group.
Conclusion The school-based fluoride mouth rinsing program indicated a significant tendency of preventing future caries incidence among children with permanent dentition.
