| Abstract | ||||
| Aim: To investigate the effect of four different cutting tools on the adaptation of resin composite to enamel. Materials and methods: Twenty extracted sound human premolar teeth were used. Occlusal surfaces were ground flat and four random groups were formed according to the received surface treatment as follow, 600-grit silicon-carbide paper (control), carbide-bur, diamond-stone and air abrasion. Two successive layers of self-etch bonding agent were applied followed by composite build-up. Teeth were sectioned longitudinally, the interface between composite and enamel was examined by SEM and micrographs were obtained. Results: the best adaptation and least surface roughness were seen in the control group while the roughest surface was observed in the air abrasion group with presence of scanty microgaps. | ||||
