A Novel Enamel and Dentin Etching Protocol Using alpha-hydroxy Glycolic Acid: Surface Property, Etching Pattern, and Bond Strength Studies

摘要

Objectives: To determine the use of alpha-hydroxy glycolic acid (GA) as a surface pretreatment for dental restorative applications. The etching pattern of GA pretreatment of dental hard tissues was assessed by surface microhardness and scanning electron microscopy (SEM). The effectiveness of GA surface etching on the enamel and dentin resin bond strengths was assessed using two etchant application modes (rubbing and no rubbing) and three adhesive systems (Single Bond [SB], One Step Plus [OSP], and Scotchbond Universal [SBU]).
