A 1‑Year Comparative Evaluation of Clinical Performance of Nanohybrid Composite with Activa™ Bioactive Composite in Class II Carious Lesion: A Randomized Control Study

Abstract

Aim: The aim of this study was to compare and evaluate the clinical performance of nanohybrid composite with Activa™ bioactive composites in Class II carious lesion. Methodology: After ethical approval, patients were selected according to the inclusion‑exclusion criteria with minimum of two carious lesions in a single patient. Lesions were randomly divided into two groups: Group A – nanohybrid composite and Group B – Activa™ bioactive composite. After administration of local anesthetic agent, Class II cavity preparation was done followed by rubber dam application. For deep lesion, pulp protection was done with light‑cured calcium hydroxide. Then, the cavities were restored. Finishing and polishing were done. Evaluation of the restorations was done at 1 week, 6 months, and 1 year time interval by second‑blinded examiner according to the modified USPHS criteria. The results of the study were tabulated, and statistical analysis was done. Results: The results showed no statistically significant difference in the clinical performance of nanohybrid composite and Activa™ bioactive composites in Class II carious lesions at the end of 1 week, 6 months, and 1 year. Conclusion: It can be concluded that both materials showed equal and acceptable clinical performance at the end of 1 year. Both materials can be successfully be used to restore Class II carious lesions.
