Abstract : Objectives: To investigate and compare the effect of using bonding agent on retention of different sealants in permanent teeth. Materials and Methods: The sample included 180 extracted premolar teeth. Teeth were divided equally for shear bond strength (SBS) and microleakage tests. For each test, 90 teeth were divided equally into 3 main groups according to type of resin based sealant (RBS) used. Each group was further subdivided equally into 3 subgroups (a, b, c) of 10 teeth each. Buccal surfaces were flattened to test the SBS and for the microleakage test, standard cavities were performed. The buccal surfaces of all teeth were etched and 6 No-bonding subgroups did not receive bonding and 6 Bonding subgroups received bonding then cured and 6 Co-curing subgroups received bonding but cured after sealant application. Group I was sealed with Seal-it, group II with Helioseal-F, while group III with Clinpro then cured. SBS buttons were tested by using Instron machine while microleakage specimens were examined by using micro-CT after thermocycling and staining. Results: All sealants showed significant difference of bond strength between pretreatment procedures, Seal-it, Helioseal-F, Clinpro. SBS of Seal-it and Clinpro interaction with Bonding was significantly greater than those for subgroups of No-Bonding and Co-curing. Only the No-Bonding subgroups show significant difference among different materials. For microleakage results, there was significant difference in the values of Bonding among different materials, while there was no significant difference in the values of no- bonding and Co-curing among different materials. Conclusions: The use of a bonding agent before placement of fissure sealant (FS) in permanent teeth was effective in increasing bond strength and decreasing microleakage.
