Comparative Evaluation of Microleakage and Bond Strength of Activa and Vitremer in Primary Molars; An in Vitro Study

Abstract

Aim: The aim of the study is to compare and evaluate microleakage and shear bond strength of ACTIVA and VITREMER in primary molars.

Method: 120 human primary molars were randomly divided into two groups for evaluating microleakage and shear bond strength. Microleakage was assessed using dye penetration technique, and shear bond strength was evaluated on enamel and dentin. Statistical analyses were performed to compare the two restorative materials, ACTIVA and Vitremer.

Results: Results showed no significant difference in microleakage between the materials, but ACTIVA exhibited superior bond strength on enamel compared to Vitremer.

Conclusion: The study concludes that ACTIVA has advantages in reducing microleakage and improving bond strength, suggesting its potential for use in pediatric dental practice, contributing to the literature on bioactive materials in dental restorations.
