Background and objective: The objective of this study was to evaluate the bond strength between a composite resin and dental hard tissues, which have been previously irradiated with an Er:YAG (2.94 μm) or CO~2~ (9.6 μm) laser. Materials and methods: A total of 156 bovine teeth were divided into 6 gr

Background: The objective was to evaluate the morphology of enamel and dentin irradiated with Er:YAG (2.94 μm) and CO~2~ (9.6 μm) lasers. Methods: Six groups were evaluated: G1 – CO~2~ irradiated enamel (3 W); G2 – CO~2~ irradiated dentin (3 W); G3 – CO~2~ irradiated enamel (7 W); G4 – CO~2~ irradia
## Abstract The characteristics of laser‐treated tooth surfaces depend on the laser wavelength, pulse duration, spatial and temporal laser beam quality, incident fluence, surface roughness, and the presence of water during irradiation. Ablated surfaces are most commonly restored with adhesive denta
