“…Concerning root canal wall modification made by endodontic sealers and canal filling materials, it seems that these materials affect the bond between post and canal walls [15][16]20 . Resinous sealers have the ability to penetrate lateral canals, accessory canals, and dentinal tubules 7 , and their composition and depth of penetration can have specific effects in reducing the post bond strength 16 . These filled dentinal tubules may be obstructed while post spaces are being prepared, which would interfere with the formation of a hybrid layer of resin cement and dentin.…”

“…When the crown is clinically almost destroyed, intraradicullar posts are indicated to secure retention between the prosthetic crown and the remaining tooth structure [2][3] .This retention plays an important role in the durability of the final restoration 4 . Recent years have seen increased utilization of fiber-reinforced composite (FRC) posts 5 because of their advantages of desirable esthetics 6 , a modulus of elasticity similar to dentin, stress distribution along a wider surface area on root walls, and minimal risk of vertical root fracture [7][8] . Relating to the limitations in bonding to root canal dentin, numerous studies have been conducted to improve bonding of posts to tooth structures 9 .…”

Despite the increasing demand for fiber-reinforced composite (FRC) posts, their bonding to root canals is still subject to debate. Endodontic sealers may affect the bond strength between fiber posts and root canal dentin. Aim: To compare the effects of different sealers on fiber post bond strength. Methods: Sixty teeth were divided into 4 groups according to obturation method: GI, gutta-percha without any sealers; GII, gutta-percha and AH26 resin-based sealer; GIII, RealSeal point and RealSeal resin-based sealer, GIV, Guttaflow. Fiber posts were cemented into root canals. Specimens were sectioned, and the bond strength was measured in the middle area. The failure mode was evaluated. Data were analyzed by one-way ANOVA and post hoc test. Results: The highest bond strength was observed in the control group (2.95±1.12), and the least was in the Guttaflow group (1.15±0.78). There was a significant difference between bond strengths of the control and Guttaflow groups and between AH26 and Guttaflow groups (p<0.05). The failure mode was mainly adhesive between dentin and resin cement in all groups. Conclusions: Sealers may have a negative effect on the bond strength of fiber posts to root canal dentin.

Objective: To compare the bond strength of three-step and self-etch adhesive systems with and without prior acid etching on bonding of fiberglass posts in root canals. Material and Methods: Experiments were conducted on roots of five upper molars without curvature and sectioned in a cervical-apical direction. With the aid of a highspeed turbine and diamond tips, cylindrical cavities 7 mm in depth and 1.4 mm in diameter were made in the dentine. The roots of the same tooth were used, where the retainers were cemented, thus generating three groups: Group A: Adper Scotchbond Multipurpose Plus (SBMP) + Rely X ARC; Group B: Single Bond Universal (SBU-1) + Rely X ARC, with acid etching prior to adhesive insertion; Group C: Single Bond Universal (SBU-2) + Rely X ARC. The samples were stored in a bacteriological incubator at 37ºC with 100% humidity for 48h and were subsequently cross-sectioned to obtain 3 dentine discs 1mm in thickness. Forty-five specimens were subjected to the push-out test. Results: Through the analysis of variance and Tukey's test, it was found that SBMP showed, with statistical significance (p<0.05), highest bond strength when compared with the SBU-1 and SBU-2 systems. The observed difference in the discs was located in the cervical portion. Conclusion: The three-step adhesive system had higher bond strength with the substrate than the self-etching adhesive only in the disc in the cervical portion; further, statistically, the prior application of phosphoric acid in SBU-1 did not affect its bond strength significantly.

“…20,21,23 Cecchin et al 20 proposed that the epoxy resin component of resin-based sealers may have increased affinity for various components of the resin cement. However, in contrast to studies by Cecchin et al 20,21 , the calcium hydroxide-based sealer group in the present study was associated with lower bond strength values relative to control and resinbased sealer groups. This result, compatible with 30 is due to the composition of Sealapex, which contains isobutyl salicylate; salicylate is known to react with calcium solubilized by the dissolution of Sealpex.…”

“…[26][27][28] Some studies indicate that the bond strength of eugenol-based sealer is decreased when used in association with resin cements. 3,20,24 Residual eugenol on the dentin surface could affect the polymerization of resin cements, and the diffusion of eugenol into the dentin tubules could dramatically decrease adhesive efficiency. 29 The lowest bond strength values in the current study were occurred after use of the eugenol sealers, however, no significant difference was observed in bond strength between calcium silicate and eugenol sealer, in contrast to results reported in Özcan et al 24 Calcium silicate-based sealers show an approximate 20% expansion, and removal of these sealers with conventional re-treatment methods is not possible.…”

ÖZETPurpose: The present study evaluated fiber post bond strength in root dentin using various root canal sealers and resin cements. Material and Methods: After root canal preparation, teeth were divided into 5 distinct groups (Sealapex (calcium hydroxide-based); AH Plus (resin-based); Tubli-Seal (eugenol-based); BC Sealer (bioceramicbased) and No Sealer (control) according to root canal sealer used. After root filling, post space preparations were done. Five main groups were subdivided into 3 groups (self-etch, etch-and-rinse, and self-adhesive) corresponding to the resin systems applied. After post cementation, 3 slices were obtained from different regions (coronal, middle, apical) for push-out testing. SEM images of specimens were obtained to evaluate for debonding failures. Differences in bond strength were evaluated by ANOVA and Post-hoc Tukey HSD methods. Results: It was observed that in Tubli-Seal, BC Sealer and Sealapex groups the bond strength was significantly decreased (p < 0.01). No significant difference (p > 0.05) in bond strength values was observed between the AH Plus and control groups. It was also observed that the bond strength values were similar (p >0.05) in different resin cement systems. Conclusion: Root canal sealers affect bond strength between fiber posts and the root canal dentin, whereas different resin cement systems have no effect on the bond strengths. Keywords: Bond strength; fiber post; push-out; resin cement; root canal sealer. ABSTRACTAmaç: Bu çalışmada farklı kök kanal patları ve resin simanlar kullanılarak fiber postun kök dentinine olan bağlanma dayanımı değerlendirildi. Gereç ve yöntem: Kök kanal preparasyonu yapıldıktan sonra kullanılacak kök kanal patına göre dişler 5 farklı gruba (Sealapex (kalsiyum hidroksit esaslı); AH Plus (rezin esaslı); Tubli-Seal (öjenol esaslı); BC Sealer (biyoseramik esaslı) ve kontrol grubu(kök kanal patı kullanılmadan) ayrıldı. Kanal dolguları uygulandıktan sonra post boşluklarının preparasyonu gerçekleştirildi. Beş grup, post yapıştırılmasında kullanılacak rezin siman tipine göre, 3 alt gruba (self-etch, etch-and-rinse ve self adeziv) ayrıldı. Postların yapıştırılmasını takiben push-out testi için farklı bölgelerden 3 adet kesit (koronal, orta, apikal) alındı. Test uygulanan örneklerden bağlanma başarısızlıklarının değerlendirilmesi amacıyla SEM görüntüleri elde edildi. Bağlanma dayanımı farklılıkları ANOVA ve Post-hoc Tukey HSD testleri ile değerlendirildi. Bulgular: Bağlanma dayanımının Tubli-Seal, BC Sealer ve Sealapex gruplarında anlamlı derecede düşük (p<0.01) olduğu saptandı. AH Plus grubu ve kontrol grubu arasında anlamlı bir farklılık olmadığı (p>0.05) tespit edildi. Farklı resin siman sistemlerinde de bağlanma dayanımı değerlerinin benzer (p>0.05) olduğu görüldü. Sonuç: Kök kanal patları fiber post ile kök dentini arasındaki bağlanmaya etki ederken, farklı rezin siman sistemlerinin bağlanma dayanımı üzerine bir etkisi yoktu.
