ABSTRACT
Introduction:
The aim of this study was to evaluate the composite surface treated by different powers of Erbium-Doped Yttrium Aluminum Garnet [ErYAG] laser in comparison with bur preparation via scanning electron microscope.Methods:
Fourteen composite resin blocks with 15× 10 × 10 mm dimensions were used in this study. The samples were divided to seven groups as follow Group 1 [power 1 W, Energy 50 m/l]; Group 2 [power 2 W, Energy 100 m/l]; Group 3 [power 3W, Energy 150 m/l]; Group 4 [power 4 W, Energy 200 m/l]; Group 5 [power 5W, Energy 250 m/l]; Group 6 [power 6 W, Energy 300 m/l]; Group 7 Diamond bur. Then, the samples were prepared for SEM examination.Results:
The surface treated by ErYAG laser showed irregular and micro porous surface.Conclusion:
It seems that composite surface treatment by ErYAG laser can be an alternative method for composite repair if suitable parameters are used
