Abstract:

The Er,Cr:YSGG laser demonstrates significant advantages in the treatment of dentin hypersensitivity.Through its thermal effect,this laser causes the denaturation of organic substances and the melting of inorganic substances within the dentinal tubules,thereby effectively sealing the dentinal tubules and rapidly relieving the symptom of hypersensitivity. At the same time,the treatment process is comfortable,and patients have a high degree of acceptance.This article systematically reviewed the advantages of Er,Cr:YSGG laser in the treatment of dentin hypersensitivity.Combined with the research findings in histology,it deeply expounded on the mechanism of dentinal tubule sealing by this treatment method and the morphological impact on the surrounding tissues. The aim was to provide a theoretical basis and practical guidance for the rational,safe,and efficient treatment of dentin hypersensitivity in clinical practice.

Key words: Er,Cr:YSGG laser, Dentin sensitivity, Thermal effect, Desensitization therapy
