Abstract: Purpose: The aim of this study was to evaluate the influence of marginal configuration on adaptability of two resin restoratives using the nanoleakage technology. Material and Methods: Thirty freshly extracted teeth were selected, and divided into three groups 10 teeth each. Class V cavities were prepared on the buccal and lingual surface of each tooth with three different occlusal marginal configurations, namely, butt joint, short bevel and long bevel. The gingival marginal configuration was terminated by a hollow ground bevel to serve as a control. The prepared teeth were restored with two resin composites, Z250 (minifill) and Supreme (nanofill), thermally cycled and then coated with nail varnish. The teeth were immersed in %50 w/v solution of silver nitrate for 24 hours, then exposed to photodeveloping solution for 8 hours. The sample were cut longitudinally through the center, polished, gold coated, and observed in a field emission SEM. Results: The results were analyzed by two-way ANOVA and Tukey HSD test at 0.05 significant levels. Butt joint occlusal marginal configuration showed significantly higher nanoleakage scores, long and short bevels showed the least nanoleakage scores, and the two marginal configuration were not significantly different.
