Pit and Fissure Sealant Versus Fluoride Varnish In Prevention of Occlusal Caries

Introduction: It was to compare the efficacy of semiannually fluoride varnish application versus pit and fissure sealant to reduce occlusal caries incidence. Materials and methods: A randomized parallel designed study was conducted with 352 children aged 6-7 years. Participants were allocated into biannual application of varnish (n=179) (NaF 5 %( Durafluor, DENTSPLY®, Latin America) or resin-based fissure sealant (n=173) (Eco Seal, Korea®) single application without previous tooth preparation. Two visual-tactile methods including WHO and Nyvad criteria were used for caries detection. The unit of analysis was tooth surface. χ2 test, t-test, Fisher exact, and multivariable logistic regression were used for statis
