“…Moreover, the push-out bond tests simulate clinical situations more closely [20]. The clinical success of a post-and-core restoration depends on post retention, as debonding is the most common cause of failure for fiber-reinforced posts [21,22]. Moreover, proper adhesion at the postresin interface is important for distributing the stress generated during occlusion [23,24].…”

The purpose of this in vitro study was to evaluate the push-out bond strength of fiber-reinforced resin posts using self-adhesive cements with different adhesive systems. A total of 50 single-rooted human maxillary premolars with fully developed apices and 15–16 mm straight root canals were selected. The teeth were divided into 10 groups with coronal and apical parts according to the adhesive bonding system and luting material used: one universal adhesive with MDP-containing self-adhesive resin cement; another universal adhesive with MDP-containing self-adhesive resin cement; universal primer with MDP-containing self-adhesive resin cement; universal primer with dual-cure resin cement; MDP-containing self-adhesive resin cement only (Control). Each specimen was subjected to a fatigue load of 600,000 cycles using a chewing simulator with sliding movement and cut horizontally for push-out bond strength testing. Statistical evaluation consisted of a one-way ANOVA test using SPSS v23.0. The highest bond strength (7.05 MPa) was obtained in the coronal part of the Single Bond universal group treated with MDP-containing self-adhesive resin cement and the lowest strength (4.77 MPa) was observed in apical part of MDP-containing self-adhesive resin cement group (Control). However, the one-way ANOVA results showed no significant difference between all 10 groups (p > 0.05). The self-adhesive cement without adhesive bonding showed no statistically different value compared to self-adhesive cements with adhesive bonding.

“…Even though the utilization of a fiber post could reduce the incidence of root fracture, failure can still occur through decementation of the fiber post from the canal 4,5) . The flexibility of fiber posts allows them to consensually bend with dentin during function, resulting in debonding of the interface when the bond strength is inadequate.…”

The purpose of this study was to evaluate the flexural properties and surface topography of fiber posts surface-treated with various etching protocols. Seventy each of three types of fiber posts: RelyX Fiber Post, Tenax Fiber Trans, and D.T. Light-Post Illusion X-Ro, were randomly divided into 7 groups: no surface treatment, surface treated with hydrofluoric acid (HF) 4.5% for 60 s, HF 4.5% for 120 s, HF 9.6% for 15 s, HF 9.6% for 60 s, HF 9.6% for 120 s, and treated with H2O2 24% for 10 min. The specimens were then subjected to a three-point bending test. Surface topographies of the posts were observed using a SEM. The results indicate that fiber post surface pretreatments had no adverse effects on the flexural properties. However, the fiber posts treated with high HF concentrations or long etching times seemed to have more surface irregularities.

“…Fiber reinforced composite resin (FRC) posts possess exceptional aesthetic properties and an elastic modulus which closely matches dentin which reduces the risk of severe tooth fractures compared to metal posts 2,3) . However inadequate adhesion between root dentin and posts have caused clinical complications such as post debonding [4][5][6] ; therefore it is important to have sufficient adhesion between root dentin and post material for adequate post retention. Studies on the adhesive or retention force between dentin, post, and core materials have been reported 7,8) ; however very few have investigated the relationship between bond strength of root dentin to resin composite and retention force of FRC posts.…”

Effects of calcium hydroxide reagent on the bond strength of resin cements to root dentin and the retention force of FRC posts

et al. 2017

The aim of this study was to determine the effects of calcium hydroxide (Ca(OH)2) treatment on bond strength of resin cements to root dentin and retention force of fiber-reinforced composite (FRC) posts. Bovine root dentin was endodontically prepared and treated with Ca(OH)2 for 7 days. Root dentin for bond strength test was adhered to resin-composite with resin cements. For pull-out test, posts consisting of FRC posts and resin-composites were fabricated and cemented to root. Shear bond and pull-out tests were performed using a universal testing machine. No significant differences in bond strength and post retention force were found between Ca(OH)2 treated and untreated groups. Significant differences were found among the cements. A positive correlation was indicated between bond strength of cements and retention force of FRC posts. In conclusion, Ca(OH)2 treatment on root dentin did not affect bond strength of resin cements and retention force of FRC posts.
