A One-Year Comparative Evaluation of Clinical Performance of Activa™ Bioactive composites with Microhybrid Composite In Abfraction Lesions: A Randomized Control Study

Abstract

Aim This double-blind randomized controlled study aimed to compare and evaluate the clinical performance of Activatrade bioactive composites with microhybrid composites in abfraction lesions. Methodology Thirty-four teeth having abfraction were randomly divided into two groups n17 per group depending on the restorative material used. Group Andash Microhybrid composite and Group B ndash Activa composite. Initially occlusal contacts were evaluated for the patients and required occlusal adjustments were carried out. Restorations were done according to the manufacturerrsquos guidelines. Evaluation of the restorations was done at baseline 1 month 6 months and 1-year time interval by two blinded examiners as per the modified United States Public Health Service USPHS criteria. The statistical analysis was carried out and the results were tabulated.Results The clinical performance of microhybrid and Activa showed no statistically significant difference at post-op 1 month 6 months and 1 year pgt0.05. In intragroup assessment between baseline and 6 months both groups yielded similar clinical behavior whereas at 1 year a statistically significant difference p0.046 was noted with marginal adaptation in microhybrid group.Conclusion Acceptable clinical performance was shown by both groups by the end of 1 year. However discrepancies were noted in the marginal adaptation criteria for microhybrid. Active composites can be considered as the material of choice for restoring abfraction.
