Abstract. A method of laser texturing of hard tissues of human teeth with erbium lasers radiation in ablative and sub-ablative modes is described. A positive effect of laser texturing on mechanical and chemical properties of the tissue surface and quality of filling material joint with the textured tissue surface is reported.
