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.

摘要:

树脂改性玻璃离子水门汀(resin-modified glass ionomer cement, RMGIC)具有良好的物理、化学及生物学特性,适用于乳牙龋、老年根面龋、楔状缺损的治疗。表面处理是改善粘接强度的常用方法,可增进不同成分之间的物理及化学固位。本文主要介绍目前国内外关于不同牙本质表面处理方法对RMGIC粘接强度影响的研究现状。目前常用的牙本质表面处理方法为:预处理剂处理、酸蚀处理、激光处理等。预处理剂可通过提高牙本质的表面积和孔隙率来提高RMGIC的粘接强度;使用酸蚀粘接系统处理牙本质后可有效提高RMGIC的粘接强度;使用激光处理牙本质以期获得较高的粘接强度。但树脂粘接剂的使用是否会影响RMGIC中的氟离子向深部牙本质的释放从而影响修复效果需要更深入的研究。
