“…29,32 One of the main reasons for failure is the poor adhesion between the fiber post and resin systems. 33 Fiber post debonding from the root canal occurred due to poor retention. Failures may begin at the cement-dentin or cement-post interface.…”

Nowadays, demand for esthetic restorations has risen considerably; thus, nonmetal esthetic posts made of either highstrength ceramics or reinforced resins, such as fiber-reinforced resin posts, have become more and more popular. Important characteristics of fiber-reinforced posts involve a modulus of elasticity similar to dentin and their ability to be cemented by an adhesive technique. A total of 36 maxillary incisors were divided into four groups. In this study, four adhesively luted fiber-reinforced (glass fiber, quartz glass fiber, zirconia glass fiber and woven polyethylene fiber ribbon) post systems were used. Post spaces were prepared by employing drills according to the protocol established for each group, and each post was adhesively luted with one of three adhesive systems. Three segments per root apical to the cementoenamel junction (CEJ) were obtained by sectioning the root under distilled water with a carbon spare saw. The samples (total of 108 sections) were 2.0±0.1 mm in thickness and they were stored individually in black film canisters with sterile distilled water. In order to determine the bond strength, the bonding area of each specimen was measured, and specimens were attached to a device to test microtensile strength at a speed of 1 mm/min. The analyses revealed no statistically significant differences between the adhesive systems and fiber-reinforced posts. (P> 0.05). However, the coronal portion of the root dentin had the highest bond strength. Adhesive systems used along with fiber-reinforced resin posts demonstrated reliable bonding.

“…Studies, however, have shown that the polymer matrix of such fiber-reinforced posts was virtually nonreactive, because the resin has a high degree of conversion and is highly cross linked [16]. This has prompted researchers to explore the options of improving the post-cement bonding through pretreatment of post surfaces with silane either alone [8, 9, 17, 18] or following surfaces conditioning using chemical [9, 14, 18, 19] or mechanical [20] means with varying degrees of success.…”

Objective To evaluate the influence of 3 different post-resin matrix systems cemented with dual-cure resin cement in simulated root canals made of PMMA acrylic sheet. Methods 3 types of fiber posts (n = 60) with different resin matrixes divided into 3 groups: group 1 cross-linked FRC Postec Plus post (n = 20), group 2 cross-linked Rely X post (n = 20), and group 3 Interpenetrated IPN Everstick post (n = 20). All posts were cemented using Multilink Automix dual-cure cement. Posts were cemented into acrylic blocks in order to purely test the strength of cement-post interface. After one week storage at 37°C, two sections of 1 mm thickness from middle-third were subjected to micro-push-out test at crosshead speed 0.5 mm/min. Results The data were analyzed using one-way analysis of variance (ANOVA). The variable fiber post-matrix system was found to significantly affect the push-out bond strength (p < 0.001). Group 2 exhibited that the highest mean push-out bond strength was (5.36 + 2.3 MPa), and group 3 showed the lowest mean push-out (0.41 + 0.4 MPa). There was significant difference among the groups regarding the failure mode as chi-square test revealed (p < 0.001). Conclusion Prefabricated cross-linked posts with epoxy-based matrix demonstrated higher bond strength than prefabricated cross-linked posts with Bis-GMA-based matrix and posts with semi-IPN matrix when luted with dimethacrylate-based dual-cured resin cement.

“…GC Gold Label 1 demonstrated a higher incidence of fracture between the fiber post and the cementing system, whereas the higher incidence with Relyx U200 was of the mixed type. This may be due to the treatment of the surface of the fiber post with acid conditioning and silane when using Relyx U200 (Daneshkazemi, Davari, Askari, & Kaveh, ). In contrast, when glass ionomer cement was used, the surface of the post was only cleaned with 95% ethanol, without any chemical treatment, which we assign the reason for this fracture pattern type (Leme, Pinho, de Gonçalves, Correr‐Sobrinho, & Sinhoreti, ).…”

This study compared the performance of a glass ionomer (GC Gold Label 1, GIC) as a fiber post cementation system for glass fiber posts with a self-adhesive resin cement (Relyx U200, RUC) and a conventional resin cement system (Scotchbond Muli-Purpose and Relyx ARC, RAC). Thirty endodontically treated canines were randomly divided in three groups (n = 10), according to the fiber post cementation system: (RAC)-Scotchbond Multi-Purpose and Relyx X ARC; (RUC)-Relyx U200 and (GIC)-GC Gold
