Adhesion of composite materials to enamel: Comparison between the use of acid and lasing as pretreatment

Abstract

Acid-etch is presently the accepted method for adhesion of composite materials to enamel. In this investigation, we used the laser for pretreatment of the enamel instead of acid. The adhesive (tensile) strength was measured by the Instron unit and statistically analyzed. Results demonstrated that bonding strength following laser pretreatment is comparable to that of acid-etch.
