    Introduction: Sealants are considered to be more effective in preventing and arresting pit and fissure caries of primary and permanent molars. Laboratory in vitro tests play a key role in providing the necessary information regarding the efficacy of new products in a short period of time. Therefore, the aim of the present study to compare and evaluate the shear bond strength of conventional and hydrophilic fissure sealants applied to the enamel on the buccal surface of permanent molars. Materials and Methods: Twenty extracted third molars were included in the study. The teeth were randomly divided into two groups. Group I: Conventional sealant (Clinpro3M ESPE) and Group II: Hydrophilic sealant (Ultraseal XT Hydro). Buccal surfaces of each tooth were pretreated with the acid etchant, and respective sealants were placed perpendicular to the polished surfaces using an elastomeric mold. All the samples were embedded in resin block, and shear bond strength was evaluated using universal Instron machine. Independent t-test used to compare the difference in the mean shear bond between the groups and the level of statistical significance was set at a value of P < 0.05. Results: The mean shear bond strength of Group I sealant was found to be 13.71 ± 0.94 MPa and for Group II, it was 20.39 ± 0.98 MPa. Group II presented a significantly higher shear bond strength than that of Group II (P = 0.001). Conclusion: Ultraseal XT Hydro (Group II) had maximum shear bond strength than that of Clinpro sealant (Group I).
