Abstract :The purpose of this study was to investigate the morphological and chemical changes and bond strength on enamel surfaces subjected to different surface preparation. The samples were evaluated in in vitro tests with 7 different groups(acid etching, Er:YAG laser QSP mode, and Er:YAG laser MSP mode, Air-Flow, and combinations with acid). Surface profilometer and AFM were used to evaluate the surface roughness. After the surface treatment, the chemical changes were analyzed using SEM-EDS. The effects of preparation technique on the bond strength to the enamel surface were evaluated by using micro tensile and shear bond strength tests. The values obtained the surface roughness evaluation of surface profilometer and AFM were compatible with each other. The highest roughness value was found in QSP when all groups were compared. Ca/P ratios of the surfaces were evaluated as a result of SEM-EDS analysis and it was observed that Ca/P ratio increased in all groups except Acid. It was seen that the results obtained for all groups of micro tensile and shear bond strength tests were consistent with each other. In conclusion, it is considered the use of Er:YAG laser QSP settings with acid can effect the long-term success of restorations clinically.Keywords : AFM, Mine, SEM-EDS, Yüzey Hazırlığı
