Abstract

The irradiation of dental hard tissues with high-intensity lasers can make them more resistant to demineralization. Although many wavelengths have been studied, there are no research that evaluate the potential of short-pulsed 5ns Nd:YAG laser emitted in the infrared (1064nm) or ultraviolet (355nm) wavelength to prevent the progression of erosion lesions. This in vitro study evaluated the morphological and optical changes in eroded dentin promoted by such lasers. It was concluded that Nd:YAG lasers are alter the surface and optical attenuation coefficient of dentin during erosion/abrasion lesions; however, these effects are restricted to the first days of erosive/abrasive challenge.
