Comparative Evaluation of the Etching Pattern of ErCr:YSGG Acid Etching on Extracted Human Teeth-An ESEM Analysis

摘要

IntroductionEtching of enamel and dentin surfaces increases the surface area of the substrate for better bonding of the tooth colored restorative materials. Acid etching is the most commonly used method. Recently, hard tissue lasers have been used for this purpose.
