PurposeThe aim of this study was to evaluate the effectiveness of silica‐lasing method for improving the composite resin repair of metal ceramic restorations.
Materials and MethodsSixty Ni‐Cr cylindrical specimens were fabricated. The bonding surface of all specimens was airborne‐particle abraded using 50 μm aluminum oxide particles. Specimens were divided into six groups that received the following...
The aim of this in vitro study was to assess the effect of Er:YAG laser surface treatment on the tensile bond strength of a sealant in permanent teeth. A total of 30 sound third molars were selected and embedded in cold-cure acrylic resin. The enamel surfaces were flattened by a grinding. The teeth were randomly divided into three groups and pretreated as follows: (1) 37% phosphoric acid; (2) Er:YAG...
