Paper Abstract

In this study for the first time there were registered and investigated the effects accompanying the interaction with human tooth enamel of YAG: Er laser radiation at energy density below the enamel removal threshold. A comparative research of efficiency of removal of hard tissues of human tooth by YAG: Er and YSGG: Cr, Er laser radiation was carried out. There was investigated the influence of duration and structure of the YSGG: Cr, Er laser pulse on efficiency of laser removal of human tooth enamel and dentine. The most effective for destruction of tooth hard tissues appeared the pulse with general duration of about 2 millisecond, consisting of equidistant sequence of spikes, while the duration of each spike was about 500 nanoseconds.
