Abstract: BACKGROUND: Dental caries is one of the most common diseases around the world. The newly erupted permanent posterior teeth are at great risk due to the complex occlusal morphology of pits and fissures, infraocclusion and incomplete maturation of enamel. Pit and fissure sealants are the treatment of choice in such conditions. OBJECTIVES: To compare the successful outcome of pit and fissure sealants bonded with etch-and-rinse adhesive system and self-etch adhesive systems in newly erupted permanent first molars. METHODS: This randomized clinical trial was conducted at the Fatimah Jinnah Dental Hospital from June 2017 to May 2019. Children aged between 6 to 9 years who fulfilled the inclusion criteria were recruited for this study after parents’ consent. Patients were randomly divided into two groups by the lottery method. Thirty patients with 60 first molar teeth in Group A were treated with etch-and-rinse adhesive system, while the other thirty patients with 60 first molar teeth in Group B were treated with self-etch adhesive system. After adhesive placement, all children received the same fissure sealants in newly erupted maxillary and mandibular permanent first molar. Each group was clinically evaluated at 6 and 12 months follow-up visit. Modified United States Public Health Service (USPHS) criteria were used for direct clinical evaluation of successful outcomes such as sealant retention and marginal discoloration. RESULTS: Successful outcome was statistically significant in Group B compared to Group A (60% vs. 30% p= 0.020) at 12 months follow-up. Stratification analysis was performed with respect to age in which a successful outcome was not significant (p= 0.43) between groups for 6 to 7 years of age, while it was significant (p= 0.012) between groups in 8 to 9 years of age children. CONCLUSION: Self-etch adhesive system is better than etch-and-rinse adhesive system in terms of long-term sealant retention. In addition, the bonding procedure is simple with relatively short clinical application time therefore it would offer great benefit to clinicians in treating pediatric patients.
