Background: The interface of the post and resin cement is a site of likely failure of adhesion. This interface adhesion of the post surface can be improved through different pretreatments such as laser. So the aim of this study was to investigate the effects of erbium-doped yttrium aluminum garnet (Er:YAG) and erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser irradiation on the push-out bond strengths of fiber-reinforced composite (FRC) posts and resin cement. Materials and Methods: Thirty extracted mandibular premolar teeth were taken and randomly divided into three groups, Group 1 (control group), Group 2 (Er,Cr:YSGG), and Group 3 (Er:YAG). FRC post cementation was performed with Etch-and-rinse resin cement. Push-out strength was tested using a universal materials tester. Statistical analysis was carried out using Statistical Package for the Social Services (SPSS), version 20. Results: Highest push-out bond strength was observed in Group 3 (i.e., Er:YAG, 18.1±0.4MPa) followed by Group 2 (i.e., Er,Cr:YSGG, 17.6±0.9MPa) and least strength was seen in Group 1 (i.e., control, 14.7±1.5MPa). A statistically significant difference was observed when the groups were compared to the untreated or control group (P = 0.000). Conclusion: It was concluded that laser treatment, that is, Er:YAG and Er,Cr:YSGG, significantly improved the push-out bond strength of FRC posts luted with resin cement. |
