Objectives: To determine retention of resin-based pit and fissure sealant with adhesive compared to glass ionomer sealant on partially erupted second permanent molars. Methodology: The samples consisted of 157 partially erupted lower second permanent molars from 117 children aged 11-14 years. The erupting molars were randomly sealed with a resin-based pit and fissure sealant (Clinpro™ sealant) in combination with a total-etching adhesive (Adper™ Single Bond Plus Adhesive) or a glass ionomer sealant (Fuji VII®). Sealant retention was evaluated at 3 and 6 months after sealant application. The results were statistically analyzed using chi-square test at a significant level p<0.05. Results: Complete retention of resin-based pit and fissure sealant with adhesive and glass ionomer sealant were 100 and 97.4 percent at 3 months and were 97.1% and 93.1% at 6 months. There was no statistically significant difference in retention status for subjects having resin-based pit and fissure sealant with adhesive and glass ionomer sealant in both periods of evaluation. No caries was found on occlusal surfaces of all teeth throughout the 6-month recall period for both materials. Conclusion: Sealant application using a resin-based pit and fissure sealant with adhesive or a glass ionomer sealant on partially erupted second permanent molars showed no difference in retention rate. There was no caries lesion on occlusal surfaces in 6 month-period after sealant application.
