Abstract

Microleakage at the marginal area of composite resin restorations can lead to discoloration and secondary caries. Performing rebonding after finishing and polishing can reduce microleakage of composite resin restorations. This study aimed to analyze the marginal microleakage of composite resin restorations after rebonding with a surface sealant and a bonding agent. Cavity preparation was performed on the buccal side of 60 human premolar teeth (3 mm in diameter and 2 mm in depth). Samples were randomly divided into two groups for rebonding with the different materials. Group 1 samples were rebonded with the surface sealant, whereas group 2 samples were rebounded with the bonding agent. Microleakage was measured using 1% methylene blue after thermocycling. Lesser microleakage was seen in group 1 than in group 2, with a statistically significant difference between the two groups (p < 0.05). Rebonding with a surface sealant can reduce marginal microleakage of composite resin restorations better than rebonding with a bonding agent.
