Abstract: 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.
