Comparative Study of Different Cavity Configuration Effect on Marginal Adaptation of Bulk Fill Versus Conventional Resin Composites
Aim : The aim of the study is to evaluate the effect of different cavity configuration (C-factor) on marginal adaptation of Sonic fill versus Ceram X conventional composite resin composites. Subjects and methods :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); Sonicfill and Ceram X resin composites. Each group was further divided according to the cavity configuration into three equal subgroups of (15 each); flat tooth surface, class II cavity and class V cavity. Each subgroup was divided subdivisions according to storage time into three (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 splatted 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 Sonic-fill than Ceram X. C-factors do not completely eliminate the microleakage with both bulk fill resin materials. There was significant difference between flat tooth surface and both of classII and classV. Sonicfill and Ceram X showed high leakage score at six months storage time.
