This study examined the effect of air abrasion and thermocycling on the adaptation and shear bond strength, of composite resin bonded to dentin using etch-and-rinse and self-etch resin adhesives. Confocal microscopy showed both adhesives closely adapted to dentin and a significantly (<I>p</I><0.001) greater number of resin tags were observed for the etch-and-rinse adhesive. Air abrasion significantly increased resin tag length (<I>p</I><0.05) for the etch-and-rinse adhesive and significantly increased the number (<I>p</I><0.001), length (<I>p</I><0.001) and thickness (<I>p</I><0.01) of tags for the self-etch adhesive. However, air abrasion resulted in defect formation within the hybrid layer and thermocycling caused separation of the hybrid layer from adjacent dentin containing resin tags. A significant (<I>p</I><0.05) reduction in shear bond strength was observed for the etch-and-rinse adhesive following thermocycling. Both adhesive systems adapted well to dentin <I>in vitro </I>and shear bond strengths were similar. The area of tag penetration into dentin was significantly (<I>p</I><0.0001) enhanced following air abrasion.
