With technological development, some alternatives to rotary cutting instruments have been introduced for caries removal and cavity preparation. High power lasers are now widely used following their introduction for use in dental hard tissues in 1964. The erbium lasers (Er:YAG and Er,Cr:YSGG) remove enamel and dentin through a process called thermomechanical ablation. During this process, the infrared...
Dentin irradiation with erbium lasers has been reported to alter the composite resin bond to this treated surface. There is still a lack of studies reporting the effect of erbium lasers on dentin organic content and elucidating how laser treatment could interfere in the quality of the resin–dentin interface. This study aimed to evaluate the effect of erbium laser irradiation on dentin morphology and...
