Abstract
Background and Objective: The clinical use of the Er:YAG laser in cavity pr eparation has become widespread. With respect to cavities prepared with the Er:YAG laser, restorations using composite resins and glass ionomer cement s are common. The bond strength of current resin bonding systems to ground enamel is 14-30 MPa, whereas the strength to Er:YAG laser-irradiated enamel , regardless of the use or non-use of phosphoric acid etching is less than 10 MPa. Study Design/Materials and Methods: In this investigation, an ultrasonic sc aler was tested as a technique to increase the bond strength of composite r esins to the Er:YAG irradiated enamel surface. Results: The application of the ultrasonic scaler significantly increased b ond strength. Conclusion: The tensile bond strength in the groups treated with the ultras onic scaler exhibited approximately twice the strength observed in groups t reated with laser irradiation alone.
