ABSTRACT
Objective: This study aimed to evaluate the effects of thickness changes on translucency and masking ability of a recently developed single shade resin composite material with enhanced opacity comparing it with a traditional opaque-shade one.
Material and methods: Two brands of composite resins; Omnichroma blocker (OCB) and G-aenial Anterior (GA) in opaque A2 (OA2) shade were selected to enroll the study. Color coordinates of each composite were determined at 0.5, 1, and 1.5 mm thicknesses (n=10/thickness) on four different backgrounds (white baking, black baking, C4 shade porcelain baking and the backing of material itself) by using a …

Abstract:
This study tested the effect of different etching methods on the bond strength of a universal adhesive system to caries-affected (CAD)and sound dentin. Methods: forty premolars were wet grinded to expose flat occlusal midcoronal dentin. Specimens were equally divided according to the substrate; sound and (CAD) by exposing to pH-cycling for 14 days. Each dentin substrate was bonded with Single BondTM universal adhesive applied either after no etching or etching of dentin, then resin composite was built up. Specimens were tested for shear bond strength (SBS). The data was analyzed by two-ways ANOVA. Results: Single BondTM universal …
