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


Abstract in English

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.
