Clinical Assessment of a Newer Resin-based Bioactive Restorative Cement on Class II Cavities of Primary Molars: A Comparative Analysis

Introduction: Primary molars play a significant role in mastication, jaw alignment, and guiding permanent tooth eruption. However, their proximal surfaces are prone to decay due to anatomical challenges and cleansing difficulties, making restorative intervention challenges. While traditional materials such as dental amalgam, composite resin (CR), and glass ionomer cement (GIC) are commonly used, advancements in dental technology have introduced bioactive materials as promising alternatives, warranting further research to ensure optimal outcomes. Aim: The present study aimed to evaluate and compare the clinical performance of a newer resin-based bioactive restorative cement on class II cavities of primary molars over a 12-month period. Materials and methods: -value of ≤0.05, which was statistically significant. Results: = 0.04, relative risk (RR) 0.69] and III (RR 0.71), and had fewer teeth (2.3%) with score C for marginal discoloration. Conclusion: ACTIVA™ KIDS BioACTIVE-RESTORATIVE™ demonstrated a significant difference in color match at 12 months compared to other groups, while no significant differences were observed among the three materials for other evaluated parameters. Clinical significance: Moving forward toward biomimetic materials, ACTIVA™ KIDS BioACTIVE-RESTORATIVE™ is a promising material, with properties superior to that of composites and conventional GICs. Due to its remineralizing property and capability to accomplish bulk-fill restorations, it could be a great boon to pediatric dentists while performing class II restorations in primary molars.
