Abstract :

This study compared the tensile strength of acket–tooth bonds obtained after preparation of the enamel by conventional acid–etching, by Er:YAG laser etching , self–etching primer and combined treatments. Fifty five premolars were randomly divided to five groups. The teeth received five various treatments. Five specimens did not undergo bond test and were prepared for observation with scanning electron microscope (SEM) after surface treatment. The shear debonding test was performed at a crosshead speed of 5 mm/min. Failed ackets were examined by a stereomicroscope at 10x magnification to determine the bond failure interface using a modified adhesive remnant index (ARI). Mean SBS values and standard deviations for the groups were different, but no significant differences were observed in the SBS of all the groups’ evaluated. All the methods of enamel conditioning tested in this study are potentially adequate for orthodontic bonding.
