Micro-shear bond strength of resin composite cement to coronal enamel/dentin, cervical enamel, cementoenamel junction and root cementum with different adhesive systems

Abstract

The cervical area of teeth is the most unpredictable region for durable adhesive bonding. This study evaluated the adhesion potential of resin cement to coronal and cervical/root structures with a focus on enamel, dentin and cementum using etch-and-rinse and self-etch adhesive systems. Anterior teeth (N = 60) were randomly divided into six groups for adhesion tests: (a) unprepared enamel (UE), (b) ground enamel (GE), (c) mid-coronal dentin (D), (d) cervical enamel 2 mm above cementoenamel junction (CE), (e) cementoenamel junction (CEJ Show more
