Effect of Deproteinization on the Shear Bond Strength and Glue Penetration in the Enamel of Orthodontic Brackets

The aim of this study was to evaluate the effects of enamel deproteinization on the initial shear bond strength (SBS) and on the bracket/adhesive failure mode of orthodontic brackets bonded with a self-etching primer (SEP) as a primary objective. As secondary objective a Raman microscopy study was performed to assess the resin penetration into the enamel according to the three bonding protocols.
