Abstract:
Resin-modified glass ionomer cement (RMGIC) has good physical, chemical and biological properties and is suitable for the treatment of deciduous caries, aged root surface caries and wedge-shaped defects. Surface treatment is a common method to improve bonding strength, which can improve physical and chemical retention between different components. This paper mainly introduces the current research status of the influence of different dentin surface treatment methods on the bonding strength of RMGIC. At present, the common dentin surface treatment methods are pretreatment, acid etching, laser treatment, etc. The pretreatment agent can improve the bond strength of RMGIC by increasing the surface area and porosity of dentin. The bond strength of RMGIC could be effectively improved after the dentin was treated by an acid-etching bonding system. The dentin was treated with a laser to obtain a higher bonding strength. However, whether the use of resin adhesives will affect the release of fluoride ions in RMGIC into the deep dentin and thus affect the repair effect also needs further research.
