Abstract: Er:YAG laser is a free-running pulsed laser, which belongs to the middle infrared band in the electromagnetic spectrum. It is a hydrodynamic biological laser system with a specific wavelength that allows it to be absorbed by water and hydroxyapatite and can better act on water-bearing tissue, tooth tissue and bone tissue. Compared with traditional clinical operations, Er:YAG laser has the characteristics of accurate cutting, sterilization and faster healing. In enamel treatment, Er:YAG laser can improve the whitening effect of teeth, prolong the retention rate of fissure sealant and reduce the rate of caries. In dentin treatment, Er:YAG laser has little damage in the treatment of dental caries, the desensitization effect is accurate, and the bonding performance of the dentin is improved. When performing hard tissue cutting, Er:YAG laser has precise control of the target tissue, causes small thermal damage, promotes bone healing, and increases the success rate of implant surgery. Er:YAG laser has a good clinical application prospect.
