Effect of Combined Application of Er,Cr:YSGG and Sodium Fluo-ride Varnish in Prevention of Demineralization of Primary Tooth Enamel: an In Vitro Study
Background and Aim: Previous studies revealed improved enamel caries resistance after laser irradiation. Present in vitro study evaluated the effect of Er,Cr:YSGG laser with or without topical fluoride application on microhardness of primary enamel after artificial demineralization. Materials and Methods: In this in vitro study, 35 primary molars with sound surfaces were bisected and randomly ...
متن کاملShear Bond Strength of Nanocomposites to Dentin Substrate Treated with Er:YAG Laser Followed by Two Different Bonding Systems
Background and Aim: Preparation of tooth structure by laser systems produces a surface with different characteristics. Therefore, selecting an appropriate bonding system is necessary to achieve the maximum bond strength. The aim of this study was to compare the bond strength of Adper Single Bond 2 adhesive and Single Bond Univer-sal to dentin prepared by bur or laser. Materials and Methods: ...
متن کاملEffect of Conventional in-Office Bleaching and Laser Assisted Bleaching at Two Different Wavelengths on Color Stability of Glass-Ionomers
Background and Aim: Bleaching can improve the color of restorative materials and resolve problems related to discoloration or color mismatch. This study evaluated the effect of in-office bleaching method in conjunction with two different laser wavelengths on color change of two types of glass-ionomer restorative materials (light-cure and self-cure). Materials and Methods: In this experimenta...
متن کاملEffect of Er:YAG Laser Irradiation on Shear Bond Strength of Two Porcelain Laminate Veneers Bonded to Tooth Surface
Background and Aim: The conventional procedure for removal of porcelain laminate veneers (PLVs) is time-consuming and inconvenient. The purpose of this study was to evaluate the efficacy of Er:YAG laser for debonding of PLVs. Materials and Methods: Forty-eight intact extracted human maxillary anterior teeth received discoid PLVs (24 feldspathic and 24 e-max ceramic). The PLVs had 0.7 mm thickn...
متن کاملEffect of Laser Irradiation on Bond Strength of Zirconia Ceramic to Self-Adhesive Resin Cement
Background and Aim: Bonding of zirconia to resin cement is challenging, and the zirconia surface requires surface treatment to yield an acceptable bond strength. This study aimed to evaluate the effect of different surface treatments on the bond strength of zirconia to a resin cement. Materials and Methods: In this in-vitro experimental study, 60 zirconia discs measuring 12 mm in diameter an...
