Abstract

The aim of the study was to evaluate the effect of different cavity configuration (C-factor) on marginal adaptation of low shrinkage resin composites. A total of 90 freshly extracted human non-carious premolar teeth was used and divided randomly according to tested materials into two main equal groups (45 each); Silorane based resin composite and kalore resin composite. Each group was subdivided according to the cavity configuration into three equal subgroups of (15 each); flat tooth surface, class II cavity and class V cavity. Each division was divided according to storage time into three subdivisions (5 each); one month, three months and six months. After storage time and dye immersion in silver nitrate 50% wt. for 12 hours. Each tooth was split longitudinally into 2 halves and inspected under stereomicroscope to evaluate the marginal leakage of tooth restoration interface. Finally, a randomly representative specimen from each group was investigated under Scanning Electron Microscope (SEM) to evaluate the qualitative examination. The results of this study revealed that less microleakage of Silorane than kalore. All resin materials when used with the corresponding adhesive system with all C-factors do not completely eliminate the microleakage. There was significant difference between flat tooth surface and both of class II and class V. Silorane and Kalore showed high leakage score at six months storage time. Keywords: Cavity Configuration, Marginal Adaptation, and Low Shrinkage Resin Composites.
