“…Despite these drawbacks, the use of natural teeth in the evaluation of post systems has been considered acceptable by investigators in this field (7). The group sample size was in agreement with that used in studies of a similar nature (8). The teeth were stored in a chlorhexidine/ distilled water solution to prevent bacterial overgrowth during periods of storage.…”

The retention of zirconia-based ceramic posts (CosmoPost system) luted with glass ionomer and resin cements was evaluated. Thirtytwo extracted, caries-free, unrestored teeth were selected and stored in chlorhexidine and water solution. The teeth were endodontically treated and randomly assigned to two groups (n=16). Each tooth was decoronated and prepared to a depth of 10.0 mm from root surface to receive a 1.4 mm diameter zirconium dioxide post. Each group had posts cemented with either glass ionomer cement (Fuji I) or resin cement (Variolink II). The post/teeth specimens were embedded in resin blocks and subjected to tensile testing. The tensile force required to dislodge the cemented posts in a tensile testing machine was recorded. The mean stress values of both groups were analyzed for statistical differences using ANOVA and Student's t-test. Significance level was set at 5%. Mean peak forces at failure (N) and standard deviation for the tested cements were the following: Fuji I = 121.8 (±17.4) and Variolink II = 228.1 (±36.8). Posts luted with the resin cement presented statistically significant higher tensile bond strength than those retained with glass ionomer (p<0.05). It may be concluded that zirconia posts cemented with resin-based cement (Variolink II) failed at statistically significant higher values compared to those cemented with glass ionomer cement (Fuji I). Regardless of the cement type, the posts failed adhesively at the cement/post interface when subjected to a tensile force.

“…Additionally, it is postulated that the adhesive procedures are favored when the dentin is free of previous contamination from eugenol-based endodontic sealers (7,9). This behavior is observed not only for eugenol-based sealers, but also to epoxy-resin and calcium hydroxidebased sealers, as used in this study (8,10,18). Moreover, the preparation of the post space after the setting period of the sealer reduces the possibility of apical infiltration due to improved apical sealing (19).…”

Can the Cure Time of Endodontic Sealers Affect Bond Strength to Root Dentin?

et al. 2013

The cure time of endodontic sealers may influence the bond strength of fiber posts to root dentin. Forty teeth were selected and endodontically filled using calcium hydroxide cement and then divided into 2 groups according to the time elapsed between endodontic filling and post luting (n = 20): Immediately -glass fiber post luting immediately after endodontic filling; and Delayed -post luting performed 7 days after endodontic filling. The roots were also subdivided according to resin cement used for post luting (RelyX ARC and RelyX Unicem). The specimens were stored at 37°C for 24 h and sectioned in six 1-mm-thick slices from cervical, middle and apical thirds. The slice specimens were submitted to a push-out test at a crosshead speed of 0.5 mm/min, and the bond strength values obtained (MPa) were submitted to two-way ANOVA in a split-plot arrangement and Tukey's test (α=0.05). For both RelyX ARC and Unicem, the bond strength was significantly higher when the posts were cemented 7 days after the endodontic treatment. RelyX Unicem showed significantly higher bond strength values than RelyX ARC for both cementation periods. It was concluded that post luting should be made after the complete setting of the root canal sealer. Self-adhesive resin cement should be preferred for fiber post luting.

“…20,21 The other is that no decrease in the bond strength values of resin cements has been observed. 22,23 In addition, the effects of other endodontic sealers with various resin cement bond strength studies comparing these resin cements have provided contradictory results. [17][18][19] Demiryürek et al 12 concluded that either resin or eugenol-based sealers have no adverse effect on the bond strength of resin cement, but that calcium hydroxide-based sealers show results similar to those in a control group.…”

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.
