Effect of EDTA and Naocl application on bond strength of Orthodontic Brackets with resin –modified glass ionomer (An in vitro study)

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 Relationship between the Shear and Tensile Bond Strength and the Type of Adhesive Material for Bonding Orthodontic Brackets: Comparative Study

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-etchingprimer 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.
