“…It has been documented that chemical composition (size, type, distribution and percentage of fibers) and surface topography of posts affect the post-resin core bond strength. 23,25,26 In the current study, only one type of glass post (Glassix) was used to assess the effect of different surface treatment protocols on bond strength. Fiber posts have uniform, smooth surfaces limiting mechanical interlocking between the post surface and resin core.…”

Introduction: This study aimed to determine the bond strength of fiber post to composite core following surface treatment with Er,Cr:YSGG laser at different powers and sandblasting with and without thermocycling. Methods: In this experimental study, 30 fiber posts (Glassix, Nordin, Switzerland) were randomly divided into 5 groups of sandblasting, no treatment and laser irradiation at 1, 1.5 and 2 W powers. Following composite filling and mounting, 1-mm thick sections were made for pushout bond strength testing. Half of the samples in each group were subjected to thermocycling (n=15). Two-way analysis of variance (ANOVA) was used to analyze the bond strength values. Pairwise comparisons were made using Tukey test (P < 0.05). Results: Effect of treatment method on push-out bond strength of fiber post to composite core was significant (P = 0.017), while thermocycling had no significant effect on bond strength (P = 0.964). Pairwise comparison of surface treatment methods revealed no significant difference in groups with and without thermocycling (P > 0.05), but Er,Cr:YSGG laser irradiation with 1 W power yielded significantly higher bond strength than the control group (P =0.01). Conclusion: Irradiation of Er,Cr:YSGG laser at 1 W power increased the bond strength of fiber post to composite core. Thermocycling slightly decreased the bond strength at the fiber postcore interface.

Statement of problem:Surface treatment of reinforced fiber posts may not always increase adhesion, especially on post/resin based luting agent interface which is weaker than the dentin/adhesive interface. Relatively little information is available on cone beam computed tomography as non-destructive method suitable for investigating the details of the tooth structure and restoration relationship. Purpose: The purpose of this study was performed to evaluate porosities and gaps at post/ root dentin interface by CBCT and correlate them to push out bond strength of conventional and reinforced glass fiber posts after different surface treatments; hydrofluoric acid, hydrogen peroxide and sandblasting. Materials and Methods: Forty human maxillary central incisors were selected, decoronated to set the remaining tooth length to standardized length of 13mm from the root apex and endodontically treated. The prepared roots were randomly divided into 2 fiber post groups(20 per each). Group 1: white posts DC were selected. Group 2: easy-posts TM were selected. Within each group, posts were further subdivided into 4 subgroups (5 per each) according to surface treatments of the posts. Subgroup A: no treatment, the posts acting as control group. Subgroup B: etching by 9% buffered hydrofluoric acid for 1 minute and bonding. Subgroup C: immersion in 20% H2O2 for 15 minutes and double application of silane for 1 minute per each application. Subgroup D: sandblasting by alumina particles and silainization for 1 minute. Posts were cemented inside roots using Duo-link Universal TM resin cement. Samples were examined by CBCT scans to evaluate voids and porosities. The CBCT scans of intra canal posts were measured in the axial plane. All measurements were made at cervical and middle slices in the buccal, lingual, mesial & distal directions. Each specimen was transversely sectioned perpendicular to the long axis of the root to obtain a section 2 mm ± 0.1 in thickness from the root thirds as measured using a digital caliper. Each section was coded and photographed from apical and coronal surfaces using a stereomicroscope.. Three-way analysis of variance ANOVA test of significance was done comparing variables (post, surface treatment and radicular region) affecting mean values. One way ANOVA followed by Tukey's post-hoc test was performed porosities and gaps at post/ root dentin interface by CBCT and correlate them to push out bond strength of conventional and reinforced glass fiber posts after different surface treatments were confirmed..

“…In this study the shear bond strength was tested through a push-out test, seeking similarity to the clinical situation, as the push-out test evaluate a failure that occurs parallel to the adhesive interface [30,37,38]. The 2.0 mm test sample thickness was selected in order to minimize the influence of the CR fracture resistance in the bond strength of the FP-CR sample tested [39][40][41].…”

Abstract:Fiber posts (FP) are commonly used for extensive coronal reconstructions, often being associated with composite resins (CR) in order to minimize the space between the post and the intraradicular dentin. This study evaluated the shear bond strength of three different CR to a FP surface, with and without FP pretreatment with adhesive. Sixty #3 FP (Exacto Translúcido) were divided into six experimental groups (n = 10), according to the surface treatment used: G1-Filtek ™ Z250; G2-Filtek ™ P90; G3-Filtek ™ bulk fill restorative; G4-Scotchbond ™ Universal adhesive + Filtek ™ Z250; G5-Silorane adhesive + Filtek ™ P90 and G6-Scotchbond ™ Universal adhesive + Filtek ™ Bulkfill restorative. Two 2.0 mm thick specimens were obtained from each fiber post unit and submitted to a push-out test in a universal testing machine with a 5 mm/min crosshead speed and 5 Kilo-newton load cell. Mean and standard deviation values for bond strength (MPa) were: G1: 5.54 ± 1.78; G2: 1.69 ± 1.02; G3: 5.31 ± 1.58; G4: 7.39 ± 2.05; G5: 6.07 ± 1.88e G6: 5.50 ± 3.03. The results were analyzed through two-way analysis of variance (ANOVA) and statistical significant differences were determined by Tukey test (p = 0.05). When no adhesive was used, the bond strength was statistically significantly higher for G1 and G3, which were not statistically significantly different between them. Adhesive application showed statistically significantly higher bond strength only for G5. Without the FP pretreatment with adhesive, the bond strength was statistically significantly higher for the methacrylate-based resins and the FP pretreatment with adhesive increased the bond strength only for the silorane-based resin and changed the prevalence of failure mode type to cohesive in all composite resin study groups. The use of silorane-based composite resins to customize posts require the use of adhesive as FP surface pretreatment. The use of adhesive as pretreatment of simulated customized FP, regardless of the CR used, appear to improve the mechanical behavior of the FP-CR unit.
