ABSTRACT

Objective:To observe the elimination of smear layer on the dentin exposed to Er,Cr:YSGG laser with different energy and irradiating distance. Methods:The in vitro first premolar was selected and slices with 1.5 mm thickness were obtained by horizontal sectioning through the middle third of the teeth crown using a high-speed bur. Each dentinal slice was irradiated under the laser with different irradiating distance(
