The evaluation of bond strength of glass fiber posts subjected to different surface treatments

Aim: The aim of the study is to investigate the effect of different surface treatments applied to the fiber reinforced composite postsurface on post-dentin connection. In addition, bond strengths of post in cervical and apex regions have also been checked.Material and Methods: Central upper teeth were used for the study, various surface treatments (50 µm aluminium particles, Er: YAGlaser. Primer, Cojet) were conducted on the post surface except control group. Accordingly, samples were randomly divided into5 groups (50 µm aluminium particles, Er: YAG laser. Primer, Cojet and control groups) as being 10 in each group. Following thesetreatments, dentin bonding agents were applied to root canal and light was practiced for 20 seconds. Next, resin composite wasplaced on the surfaces of posts and it was cured with light for 40 seconds from 2 mm away of post cavity.Results: It was observed that there was high bond strength in Al2O3 group. A significant difference was not determined betweenpush-out bond strength of apex regions of all groups.Conclusion: It was seen that the samples in the group where aluminum particles were applied showed highest bond strength andlaser group followed this. It was also seen that there was higher bond strength in cervical region compared to apex.
