Research Progress of Glycolic Acid for Enamel and Dentin Etching

doi:10.13701/j.cnki.kqyxyj.2023.11.002

Abstract

Abstract: In the process of resin-bonded restoration, the surface treatment of enamel and dentin is a key step. At present, phosphoric acid commonly used in the clinic is a strong acid, which has an aggressive pattern of demineralization of dentin, and affects the long-term stability of the resin-dentin adhesive interface. In recent years, glycolic acid has been used as an alternative etch agent. This paper introduces the application background and the principle of glycolic acid etching, focuses on the effect of glycolic acid etching on enamel and dentin and the comparison between glycolic acid and traditional phosphoric acid, in order to provide reference for further research.

Key words: glycolic acid, etchant, enamel, dentin, bond strength
