Abstract :DOI : 10.26650/eor.2018.479 Purpose Erbium, chromium: yttrium, scandium, gallium, garnet insert ignore into journalissuearticles values(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. Materials and methods Thirty freshly dissected sheep mandibles containing bone and soft tissue were divided into 120 equal parts.  Gallium-aluminum-arsenide insert ignore into journalissuearticles values(Ga-Al-As); diode laser insert ignore into journalissuearticles values( λ =940 nm); with 1, 2 and 5 W output powers and ErCr:Ysgg laser insert ignore into journalissuearticles values( 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. Results 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 insert ignore into journalissuearticles values(p<0.05);. Conclusion ErCr:Ysgg laser insert ignore into journalissuearticles values( 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.
