Introduction: Surface pretreatment of posts is expected to increase the chemical and mechanical bond between the luting composite resin and the post by exposing the surface glass fibers and allowing the silane-coupling agent to directly react with the silicate group of the glass fibers allowing a stronger bond to form between the post and the resin cement. The best method to do this has not been definitively determined. Aim: To analyze the surface changes on glass fiber posts after pretreatment with erbium-doped yttrium aluminium garnet (Er: YAG) laser at different settings. Materials and Methods: Twenty glass fiber posts (ReforPost, Angelus, Londrina, Brazil) were divided into four groups. Group I: No surface pretreatment was performed Group II: Surface pretreatment of posts with Er: YAG laser at 1 W Group III: Surface pretreatments of posts with Er: YAG laser at 1.5 W Group IV: Surface pretreatment of posts with Er: YAG laser at 2 W. Results and Conclusion: Er: YAG laser does not damage the glass fibers at 1.5 W and at the same time clears the epoxy resin coating over the surface of the posts potentially allowing silane coupling agent to chemically interact with exposed glass fibers.
