Erbium, chromium: yttrium, scandium, gallium, garnet (ErCr:Ysgg) lasers have been frequently used in oral surgical procedures and are almost seen as alternatives to diode lasers. The aim of this comparative study was to analyze in an animal model the thermal elevation induced by ErCr:Ysgg and diode lasers in soft tissue and bone.
Thirty freshly dissected sheep mandibles containing bone and soft tissue were divided into 120 equal parts. Gallium-aluminum-arsenide (Ga-Al-As) diode laser (λ=940 nm) with 1, 2 and 5 W output powers and ErCr:Ysgg laser (λ=2780 nm) with 2.75, 4.5 and 6 W output powers were used on soft and bone tissues separately for 3 seconds with point application. Mean temperature values before and after application of the lasers were compared in soft tissue and bone.
The minimum mean temperature value was observed with 2.75 W ErCr:Ysgg laser while irradiation with 5 W diode laser created the maximum values (p<0.05).
ErCr:Ysgg laser (λ=2780 nm) with 2.75 W power generates low levels of heat compared to diode lasers and may provide safer surgery in soft and bone tissues without destructive effects of temperature increase.
铒铬钇钪镓石榴石（ErCr:Ysgg）激光已频繁用于口腔外科手术，几乎被视为二极管激光的替代品。本对比研究的目的是在动物模型中分析ErCr:Ysgg激光和二极管激光在软组织和骨组织中引起的温度升高情况。
将30个新鲜解剖的含骨组织和软组织的绵羊下颌骨分成120个相等的部分。分别使用输出功率为1、2和5W的镓铝砷（Ga-Al-As）二极管激光（λ=940nm）以及输出功率为2.75、4.5和6W的ErCr:Ysgg激光（λ=2780nm）对软组织和骨组织进行点照射3秒。比较激光照射前后软组织和骨组织中的平均温度值。
2.75W的ErCr:Ysgg激光产生的平均温度值最低，而5W的二极管激光照射产生的平均温度值最高（p<0.05）。
与二极管激光相比，功率为2.75W的ErCr:Ysgg激光（λ=2780nm）产生的热量较低，在软组织和骨组织手术中可能更安全，不会因温度升高产生破坏作用。
