Abstract

Extracted molars were used in order to study the efficiency of Erbium YAG, Holmium YAG, and Neodymium YAG radiation on the removal of dental enamel, dentin. The hard tissues were penetrated with standard energy and pulse parameters with or without water cooling, laser beam or fiber and black paint. The specimens were analyzed with SEM. Differences between laser wavelengths were observed. Morphologic alterations and crater formation depend directly on the wavelength and energy of the laser beam.
