The effect of transmitted Er:YAG laser energy through a dental ceramic on different types of resin cements.

Background And Objective: The laser debonding procedure of adhesively luted all-ceramic restorations is based on the ablation of resin cement due to the transmitted laser energy through the ceramic. The purpose of this study was to determine the effect of Er:YAG laser irradiation transmitted through a dental ceramic on five different resin cements.

Materials And Methods: Five different resin cements were evaluated in this study: G-Cem LinkAce, Multilink Automix, Variolink II, Panavia F, and Rely X Unicem U100.

Shear bond strength of four resin cements used to lute ceramic core material to human dentin.

Purpose: This study evaluated the effect of four resin cements on the shear bond strength of a ceramic core material to dentin.

Materials And Methods: One hundred twenty molar teeth were embedded in a self-curing acrylic resin. The occlusal third of the crowns were sectioned under water cooling.

Evaluation of mineral content of dentin prepared by erbium, chromium:yttrium scandium gallium garnet laser.

Laser etching has an effect on the mineral content of dentin. The aim of this study was to evaluate the mineral content of dentin prepared at three different power settings with an erbium, chromium:yttrium scandium gallium garnet (Er,Cr:YSGG) laser. The enamel of five, lower, wisdom, molar teeth was removed to expose the dentin surface.
