This paper describes a comparative study of residual heat deposition of Er:YAG and Er,Cr:YSGG lasers during ablation of hard dental tissues. Residual heat deposition was obtained from measured irradiated hard tissue temperature decay characteristics immediately following Erbium laser pulses. The measured residual heat was larger in enamel than in dentine for both Er:YAG and Er,Cr:YSGG […]
