Abstract

 

The results of hard human teeth tissues treatment by YLF: Er diode-pumped laser pulses are presented for the first time. The pulse duration of YLF: Er laser with wavelength of 2,81 μm was 1,4 ms. The removal efficiency of enamel and dentin of human tooth, diameter, depth and aspect ratio of craters formed in the hard tissues of human tooth under the influence of this laser radiation are measured for the first time in vitro.


Keywords: YLF: Er laser, dentine, enamel, human tooth, laser texturing, microdrilling, removal efficiency, aspect ratio.
