Microleakage of Er:YAG laser and dental bur prepared cavities in primary teeth restored with different adhesive restorative materials
Baghalian A et al. – The purpose of the study was to evaluate and compare the effect of erbium:yttrium–aluminum–garnet (Er:YAG) laser irradiation and conventional dental bur cavity preparation on in vitro microleakage of class V cavities restored with different adhesive restorative materials and two types of self–etching adhesives in primary teeth. The Er:YAG laser–prepared teeth restored with composite and Clearfil SE Bond demonstrated a better marginal seal on occlusal and gingival margins compared with that of bur–prepared cavities. The degree of microleakage in class V cavities was affected by the type of adhesive restorative materials, type of self–etching adhesive, cavity margin location, and tooth preparation method either by Er:YAG laser or dental bur.
