Abstract

Abstract: Objective: To investigate the influence of Er:YAG laser treatment on the dentin surface and bonding strength. Methods: Thirty fresh extracted molars without dental caries or restorations were collected, and enamel layer was removed with a high speed bur under flowing water. Fifty specimens were obtained by mesiodistal sectioning of each tooth and were randomly divided into 5 groups (Group A-E). Two specimens were randomly chosen from each group and were observed by scanning electron microscope. The other eight specimens in each group were bonded with light-cured composite resin and the shear bond strength was tested. Results: The highest shear bond strength was 7.11±1.73Mpa in Group C. Group E was lower than Group C. There was no significant difference between Group E and Group A, C, D. The bond strengths of Group B was the lowest, however there was no significant difference between Group B and Group C, D, E. Scanning electron microscopy showed that after acid etching, part of the dentinal tubules were open while the diameter did not increase. The boundary between the periodontal dentin and the intertubular dentine was not clear. After laser treatment and acid etching, dentin surface was clean and dentinal tubules were open. After pure laser treatment, the honeycomb, flaky-like appearance of dentin surface was clean and had no smear layer. The boundary between the periodontal dentin and the intertubular dentine was clear. Conclusion: Er:YAG laser treatment can increase the dentin resin bonding strength, but the appropriate energy parameters need to be studied in the future.

Key words: Er:YAG laser, Acid etching , Dentin , Shear bond strength
