ABSTRACT
@#Erbium,chromium:yttrium scandium gallium garnet(Er,Cr:YSGG)laser is mainly used for root canal treatment,periodontal disease,tooth decay,dentin hypersensitivity,pulp amputation,etc in the field of dentistry.This paper mainly describes the research progress of Er,Cr:YSGG laser in root canal therapy from following four as⁃pects:root canal sealing,sterilization,cavitation effect and the effect on periapical tissue. The experimental results showed that when the operation parameters of Er,Cr:YSGG were 2 ~ 4 w and 20 Hz,it could effectively remove the stained layer of dentin tubules and improve the tightness between materials and dentin. The thermal effect produced by Er,Cr:YSGG energy has a sterilizing effect,while the optical conductivity of the tooth enables the rinse solution to enter deeper tissues,further improving the sterilizing effect. Er,Cr:YSGG also has a cavitation effect,which destroys the surface tension of the deep solution,removing the stain layer and bacteria in the deep layer. However,with the same operation parameters,if Er,Cr:YSGG is not used properly,the thermal effect of Er,Cr:YSGG will cause some damage to the periapical tissues. Therefore,reasonable use time of Er,Cr:YSGG and water cooling conditions are important.
