Aim: To evaluate the effect of different enamel conditionings on the shear bond strength (SBS) and bond failure patterns of a resin modified glass ionomer cement (RMGIC) used to bond ceramic brackets. Methods: 105 human premolars extracted for orthodontic reasons were divided into 7 groups according to the enamel surface treatments: conditioners (35% phosphoric acid and 10% polyacrylic acid), type of adhesive (Transbond® and Fuji Ortho LC Capsule®), washing time and drying of the surface. Results: A significant p0.05) to the group that had brackets bonded with composite resin. The two groups that had enamel prepared with polyacrylic acid and …
