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 ...

Influence of surface treatments and resin cement selection on bonding to zirconia

This study aimed to evaluate the surface changes caused in zirconia by different surface treatments and the influence of the surface treatment and cement selection on bonding to zirconia under aging. Sintered zirconia specimens were divided into five groups (n  = 31) based on the surface treatment, namely, control, air abrasion, silica coating, laser and air abrasion + laser. After surface treatment, surfac ...
