Effects of Different Application Techniques on Nanohybrid Composite Restorations Clinical Success

Abstract

Introduction: Dental composites have been used as a restorative material for a long time. However, they have their limitations. Aims: This study evaluated the effects of placement techniques on the clinical performance of class I composite resin restorations. Methods: A total of 40 patients with split-mouth design participated in this study. Each patient had two fillings according to the placement technique (either bulk or incremental packing) of the composite resin restorations. Group (A): was packed by Tetric EvoCeram bulk-fill composite resin and Group (B): was incrementally packed with Tetric EvoCeram composite resin. Restorations of the teeth were evaluated on the same day, at one week, 3 months and 6 months to determine any signs of failure according to the modified United States Public Health Service (USPHS) criteria. Results: At different follow-up periods, the results showed no significant differences for retention, marginal integrity, surface stain, gingival bleeding, and secondary caries; however, there were significant differences in color match, surface texture, and postoperative sensitivity. Conclusion: This study concluded that the nanohybrid resin composites demonstrated excellent clinical performance for 6 months follow up period.
