Bond strength and interfacial morphology of two adhesive systems to deciduous dentin: in vitro study.
This study evaluated the bond strength and the interfacial morphology of composite restorations (SMP: Scotchbond Multi-Purpose - 3M; CSE: Clearfil SE Bond - Kuraray) in primary dentin. There is no statistical difference between groups. Fracture modes revealed a weak zone in the demineralized dentin (SMP) and in the hybrid layer (CSE). The interfacial morphology was similar in both groups. The demineralized zone in bond structures has a negative influence in adhesive restorations over the time.
