Investigation of destruction of human hard tooth tissues by YAG:Cr;Tm:Er laser 2.69-um radiation

摘要

Abstract: This paper represents the first results of the investigation of an interaction between YAG:Cr;Tm;Er ($lambda $EQ 2.69 $mu@m) laser radiation and human hard dental tissues. A comparison of intact and carious enamel and dentine destruction thresholds by submillisecond pulses of YAG:Cr;Tm;Er laser is first given also.!4
