Microtensile dentin bond strength of self-etching and single-bottle adhesive systems in different cavity configurations.

Purpose: To evaluate the bond strength of a self-etching (Clearfil SE Bond) and a single-bottle (Excite) adhesive system using two cavity configurations (C-factors 5 and 1).

Materials And Methods: Class I cavities (3 x 4 x 2.5 mm) were prepared in 28 extracted human molars using diamond burs under water cooling.
