The Objective is to determined whether enamel conditioning with sodium
hypochlorite (5,25%) and EDTA prior to etching was increased shear
bond strength of orthodontic brackets bonded with resin – modified glass
ionomer. our sample consisted of 42 extracted human premolars were
randomly divided into 3 groups.
The purpose of this study was to evaluate the shear and tensile bond strengths of orthodontic
brackets bonded with self etching primer and resin-reinforced glass ionomer cement in comparison with
light cured resin adhesive.
The tested self-etching
primer and adhesive systems produced bond strength values higher than that of the light cured resin
adhesive whereas the resin-reinforced glass ionomer cement showed a significantly reduced bond strength
. Clinically, the use of self-etching primer and adhesive systems is suitable for orthodontic bracket
bonding.
