“…Comparison of air abrasion and 1.5 W power Er:YAG laser for fiber post surface treatment revealed the highest bond strength in posts treated with air abrasion [16]. However, further studies are needed to investigate the efficacy of laser surface treatment with different irradiation parameters [16]. Another study showed that treatment of fiber post with 2780 nm Er,Cr:YSGG laser (1.5 W) increased its push-out bond strength to root dentin in the entire canal length [17].…”

Background: Inadequate retention and gradual debonding of intracanal post from root dentin is a major cause of failure of endodontically treated teeth restored with fiber post. Main body: This study aimed to assess the effect of surface treatment of quartz fiber posts with different powers and motion directions of Er,Cr:YSGG laser on their pull-out bond strength to root dentin in endodontically treated premolar teeth. In this study, 105 fiber posts were divided into 7 groups according to their surface treatment with different powers of Er,Cr:YSGG laser at 2780 nm wavelength, 20 Hz frequency and 150 μs pulse duration in circumferential (C) or longitudinal (L) motion directions: Control group (no treatment), 0.5 W laser in longitudinally (L0.5), 1.0 W laser in longitudinally (L1), 1.5 W laser in longitudinally (L1.5), 0.5 W laser in circumferentially (C0.5), 1.0 W laser in circumferentially (C1) and 1.5 W laser in circumferentially (C1.5). After cementation, pull-out bond strength was measured in Newton (N). Each sample was inspected under a stereomicroscope at × 25 magnification to determine the mode of failure. Two samples of each group were inspected under a scanning electron microscope (SEM). Data were analyzed using two-way ANOVA and Tukey's test with significant level of 0.05. The pull-out bond strength of 0.5 W groups had significant differences with the control group (P = 0.009). The bond strength of 1.0 W and 1.5 W groups were not significantly different (P = 0.630) but were higher than the control and 0.5 W groups (P < 0.001). Motion direction of laser irradiation had no significant effect on the bond strength (P = 0.384). The interaction effect of power and motion direction of laser irradiation had no significant effect on the bond strength (P = 0.092). Conclusion: Fiber posts treated with 0.5, 1.0 and 1.5 W Er,Cr:YSGG laser showed higher bond strength to dentin compared to posts with no surface treatment. However, the motion directions of laser irradiation had no significant effect on the bond strength. In order to minimize damage to post surface and achieving maximum bond strength, longitudinal surface treatment of posts with 1.0 W power of Er,Cr:YSGG laser is recommended.

Statement of the problem: Despite the fact that adhesive luting is recommended for teeth rehabilitation with glass fiber posts, the most common failure of these restorations is debonding of the glass fiber posts. Aim: To evaluate the effect of laser surface treatment of glass fiber posts on their bond strength to intraradicular dentin at different root levels. Materials and Methods: Twenty extracted single-rooted permanent human teeth were decoronated and endodontically treated. Post space of 10 mm length was prepared to receive glass fiber post. Teeth were randomly divided into 2 groups based on the surface treatment applied to the post surface as follows; Group A (Control): post surface received conventional silane treatment, Group B: Er:YAG laser was applied to the post surface followed by silane application. Prepared post spaces of all teeth were irrigated using standard irrigation protocol then dried and self-adhesive resin cement was used for posts cementation. For push-out bond strength evaluation, three slices for each sample were prepared, and the test was performed using a universal testing machine at a crosshead speed of 1 mm/min. Results: Statistical analysis showed that group B provided significantly higher bond strength values compared to group A. When different root sections were compared in each group: group A showed a significantly higher bond strength values in the middle and apical sections compared to cervical (p<0.05), while no significant difference was noticed between all sections in group B (p>0.05). In addition, the Comparison between both groups in each section revealed that: group B showed significantly higher bond strength values in cervical and apical sections than group A. While in the middle section, group B recorded a non-significant increase in the bond strength compared to group A. Conclusion: Er: YAG laser treatment for the post surface can be used as an alternative to conventional silane treatment to enhance its bonding to intra-radicular dentin.

Influence of different surface treatments on push-out bond strengths of fiber-reinforced posts luted with dual-cure resin cement

Abstract: Air abrasion attained higher bond strengths when FRC posts were luted to dual-cure resin cement. Additional studies should be designed with different types and parameters of laser devices to understand the effect of these devices on bond strength.
