Objective: Enamel and dentin bond strengths of restorative glass carbomer material were determined by shear bond strength (SBS) test after different surface treatments in this study.Materials and methods: Flat enamel and dentin surfaces pre-treated with 37% phosphoric acid (15s for enamel and dentin), or 20% polyacrylic acid (15s for enamel and dentin). Glass carbomer applied to the treated and non-treated surfaces. Conventional glass ionomer without any surface treatment served as a control.Results: Enamel and dentin SBSs of the conventional glass ionomer cement were significantly higher than those of the glass carbomer material bonded to enamel and dentin without any surface treatments. Acid-etching and polyacrylic acid pre-treatments yielded similar enamel bond strength to that of glass ionomer cement. For dentin bonding, only polyacrylic acid pre-treatment improved SBS of glass carbomer to dentin surface.Conclusions: Clinicians may consider the use of polyacrylic acid conditioner prior to the use of glass carbomer material.
