Abstract

Background: In clinical practice, the restoration of non-carious cervical lesions is a challenge, because most of the time the cervical margin is located in cementum or dentin. This characteristic makes the cervical margin more susceptible to microleakage, causing marginal stains, postoperative sensitivity and recurrent caries. Aim: To compare the microleakage and bond strength for teeth restored with Activa Bioactive restorative and nanohybrid composite resin Materials and methods: Twenty permanent premolars were selected with class V cavities for microleakage, and 20 permanent premolars were selected for shear bond strength. Microleakage was checked using dye penetration method under digital microscope Universal testing device was used to assess the shear bond strength. Leakage scores, mean and standard deviation values for shear bond strength were calculated from the recorded values. For numerical data student t-test was performed to detect the significance between both groups. For categorical data analysis Chi square test was done. Results; There was non-significant difference between ACTIVA bioactive restorative group and nanohybrid composite resin group in both parameters; leakage and bond strength Conclusion: Based on the results of the present study, the type of restorative material did not appear to have a significant influence on microleakage or bond strength
