| Abstract: | Background: Imperfect margin adaptation of class II composite resin restorations leads to clinical failure. Plasticization of bulkfill composite resins may overcome the problem. Objective: The objective of this study was to evaluate effect of composite resin preheating and ultrasonic plasticization on marginal adaptation of class II restorations in comparison with room temperature composite resin under scanning electron microscope at 200x magnification. Materials and methods: Box-only class II cavities were prepared on 30 extracted human maxillary premolars, with the dimensions of 3 mm buccolingual width, 2 mm mesiodistal width and 4mm occlusogingival depth. They were divided into three groups of 10 teeth each Group I –Cavities restored with room temperature bulkfill composite resin, Group II – Cavities restored with preheated bulkfill composite resin, Group III – Cavity restored with ultrasonically plasticized bulkfill composite resin. The tooth - restoration interface was evaluated for the marginal adaptation under SEM at 200 × magnification. The micro morphological evaluation of the tooth restoration interface was carried out according to criteria by Blunck and Zaslansky. Results: Statistical analysis done by applying Kruskal Wallis test. Group I showed higher marginal discrepancy with score 4 - severe gap of > 2µm with severe marginal irregularities, with statistically significant difference (p-value - 0.018) compared to group II and III. Group II and III demonstrated score 3 - gap visible upto 2µm with no marginal irregularities, without statistical significance. Conclusion: Ultrasonic plasticization with good clinical handling properties may be an alternative for class II composite resin restorations. |
