STATEMENT OF THE PROBLEM Porcelain veneer materials are translucent and are therefore affected by their thickness as well as the color of the underlying substructure, which limits their masking ability and compromises the esthetic result in heavily stained teeth. PURPOSE The purpose of this study was to compare the contrast ratio (CR) and masking ability of three different veneering ceramics ...

BACKGROUND AND OBJECTIVES The removal of porcelain veneers using Er:YAG lasers has not been previously described in the scientific literature. This study was designed to systematically investigate the efficacy of an Er:YAG laser on veneer debonding, possibly without damage to the underlying tooth, and preservation of the veneer integrity. STUDY DESIGN/MATERIALS AND METHODS The Fourier Transfo...

AIM The aim of the study is to evaluate the effect of ceramic type, thickness, and time of irradiation on degree of polymerization of dual-cure resin cement. MATERIALS AND METHODS Dual-cure resin cement (SoloCem) was used to prepare disk-shaped samples (0.5 mm thick × 5 mm diameter). Study group samples (n = 5) were light-cured for 40, 60, and 80 s through all ceramic leucite-reinforced (Cerg...

Laminated veneer lumber (LVL) is an engineering product material used as girders, beams, joist, headers, panels, etc. in construction. In this study, the effect of ply combination on oven-dry specific gravity, equilibrium moisture content, thickness swelling and water absorption, tensile-shear strength, modulus rupture, elasticity compression strength parallel to grain LVL manufactured from ald...
