Microtensile bond strength of different types of glass ionomer cements to Er,Cr:YSGG laser prepared dentin

抄録

Introduction: Dental lasers for cavity preparation have been in existence since the 1960s. The erbium laser such as Er:YAG and Er,Cr:YSGG are commonly used for cavity preparation as alternative methods instead of using the high speed hand piece. Many investigations have focused on the bond strength of composite resin and adhesive systems to dentin prepared by these laser systems. There are a few reports about the bond strength of glass ionomer cement to laser prepared dentin. The purpose of this study is to determine the microtensile bond strength of three different types of glass ionomer cements to Er,Cr:YSGG laser prepared dentin.
