Fig. 6From: The effect of dentin surface pretreatment using dimethyl sulfoxide on the bond strength of a universal bonding agent to dentinMicroleakage in self-etch groups, (a) and (b) microleakage in DMSO treated samples. Microleakage is seen in both occlusal and gingival walls of the cavity (yellow arrow), (c) and (d) microleakage in the samples without DMSO treatment. Microleakage is seen in both occlusal and gingival walls of the cavity (yellow arrow). RC: resin composite, DN: dentin, and P: pulp chamberBack to article page
