不同酸蚀模式对通用型粘接剂粘接效果的影响

Influence of Different Etching Modes on Bonding Effects of Universal Adhesives

通用型粘接剂是一类既可使用酸蚀冲洗模式,又可以使用自酸蚀模式的粘接剂,临床应用简单便捷,因此受到了口腔医生的青睐。然而,不同酸蚀模式的原理、临床应用条件及粘接效果可能存在差异。本文就通用型粘接剂在不同酸蚀模式下的粘接效果进行综述,结果发现针对不同牙体组织界面应采取不同的酸蚀模式。对于釉质粘接,使用酸蚀-冲洗模式的粘接效果更好;对于牙本质粘接,超温和型通用型粘接剂更适合选择酸蚀-冲洗模式,温和型通用型粘接剂更适合自酸蚀模式;对于特殊的牙齿组织例如氟牙症和硬化牙本质,酸蚀-冲洗模式能够更加有效的粘接,而龋病影响的牙本质在不同酸蚀模式下粘接强度没有差异。

Universal adhesives can be used for both etch-and-rinse and self-etch approaches.Their clinical applications are simple and convenient,so they are favored by many dentists.However,different etching modes bring different bonding effect.In this study,the bonding effect of different etching modes of universal adhesives were reviewed.For enamel bonding,the use of etch-and-rinse mode resulted in higher bond strengths than self-etch mode.For dentin bonding,etch-and-rinse mode was more suitable for super mild universal adhesives and self-etch mode was more suitable for mild universal adhesives.For special tooth surface such as dental fluorosis and sclerotic dentin,the application of acid etching was able to bond more strongly,as for caries affected dentin,there was no significant difference in the bonding strengths between two etching modes.
