Effect of 5,25% Sodium Hypochlorite Enamel Deproteinization on the Initial Shear Bond Strength and Glue Penetration in the Enamel of Orthodontic Brackets Bonded With a Self-etching Primer: An In Vitro Study on Human Bicuspids.

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.
