Microleakage of composite fillings in Er,Cr:YSGG laser‐prepared class II cavities

Abstract

Although it was found in previous studies that there is no significant difference between bond strength of acid etched enamel and Er,Cr:YSGG laser etched enamel, the dye penetration rate differs. On the basis of the results of our study, the additional use of etching after Er,Cr:YSGG laser preparation is recommended as it is used in the classical cavity preparation technique.
