ABSTRACT
AIM: The aim of the study is to evaluate the efficacy of intensive application of sodium fluoride varnish in reducing caries incidence among children aged 6 to 7 years. MATERIALS AND METHODS: The study was a randomized controlled trial conducted among 6- to 7-year-old children of Sangamner, Maharashtra, India. Nearly 200 randomly selected children were randomized into two groups: Control group and intervention (varnish) group. Dental examination to record the caries experiences was conducted at baseline and at 1-year follow-up. The fluoride varnish was applied for three times in a week for a period of 1 year. Mean decayed, missed, and filled teeth (DMFT) were compared between and within groups using t-test. RESULTS: Out of 200 participants, there were 3 dropouts for control group and 4 for intervention group. Nearly 55% study participants were males and remaining were females. There was a statistically significant difference between the baseline and follow-up caries levels in varnish group for deciduous dentition. Mean caries reduction in this study was 26%. CONCLUSION: After 1 year of study, we found significant caries reversal in deciduous dentition among the 6- to 7-year-olds after intensive fluoride application. Such a regimen can be advocated to encourage the practitioners and the caregivers alike for early caries prevention. CLINICAL SIGNIFICANCE: Intensive fluoride application (three times a week) once a year was found to be effective in reducing the incidence of detectable carious lesions and can be advocated to the dental professionals to be incorporated in their routine preventive clinical practice.
