“…Authors explained this result as the dependence of bond strength on the surface area of intertubular dentin than to tubule density. (45,46) On the other hand, our results contradict previous studies (47,48) that detected increased bond strength significantly in coronal and middle regions than apical one. Authors attributed this to morphological differences, such as the reduction in the number, density, and diameter of dentinal tubules.…”

“…FP systems are extensively preferred to restore ETT because these FPs have an elastic modulus similar to the root dentin and produce monoblock restoration, resulting reinforcement in structurally compromised roots such as flared ones. [8][9][10][11] The self-adhesive resin cement does not require any pretreatment of the tooth surface. Once the cement is mixed, its application steps are quite simple.…”

“…10 Laboratory and finite element analysis (FEA) studies also revealed that FP can protect remaining tooth structures against extensive fracture loads that can cause catastrophic (nonrestorable) failures. [11][12][13] They facilitate creating a monoblock restoration that acts as a single unit against masticatory forces. 14 It is of great importance to improve the prognosis of ETT with weakened roots facing higher fracture risk by obtaining a better monoblock structure.…”

Aim: Intraradicular post systems have become an important treatment method for endodontically treated teeth as they provide retention for restoration to the remaining tooth structure. The objective of the present in vitro study was to evaluate the effect of different fiber post-application techniques on the fracture resistance of premolars with flared root canals and no ferrule. Materials and Methods: Sixty freshly extracted, single-rooted mandibular premolars with no ferrule were endodontically treated by an experienced endodontist, and their root canals were experimentally flared. The specimens with flared root canals were divided into five groups according to fiber post-application techniques ( n = 12): a prefabricated fiber post (G1), G1 + two auxiliary posts (G2), i-TFC post system (G3), G1 + quartz splint (G4), and Ribbond (G5). The data were analyzed with analysis of variance and Tukey tests. Results: The findings were revealed that no significant difference was found among four groups, except G5 ( P > .05), which demonstrated the lowest fracture resistance ( P < .05). G2, G3, G4, and G5 exhibited dominantly restorable fracture pattern, whereas G1 exhibited nonrestorable fracture pattern. Conclusion: Within the limitations of this study, the placement of auxiliary posts, i-TFC post system, quartz splint placement, and Ribbond increased the incidence of restorable fracture compared with the controls.

“…The most frequently argument used to justify this adverse effect is the own composition of this sealer. [3][4][5][6] Eugenol interferes with the polymerization of the composite resin, changing its physical and mechanical properties. [3][4][5][6] Conversely, AH Plus, a free-eugenol resinepoxy-based root canal sealer, probably promoted a low, if any, interference with the polymerization process of the reinforce material.…”

“…1,2 Root canal sealers containing eugenol significantly compromise the bond strength of resinous materials when they are used for the placement of intracanal posts. [3][4][5][6] On the other hand, this side-effect does not occurs when the placement of fiberglass posts is performed with self-etching resinous cements after using resin-based endodontic sealers. 5 Smear layer removal prior the placement of intracanal posts enhances the penetration of resin cements into the dentinal tubules, thus favoring the interlock between the cement and dentin substrate, increasing the bond strength of restorative materials.…”

Background: This study evaluated the effects of using different root canal sealers and protocols for cleaning intraradicular dentin on the bond strength of a composite resin used to reinforce weakened roots. Material and Methods: Sixty-four roots of extracted human maxillary canines were weakened, prepared and filled with two different endodontic sealers (Endofill and AH Plus). In half of the sample, set aside for each respective sealer, excess filling material was cleaned. In the other half, the weakened areas were not cleaned, and the excess of sealer was spread on the intraradicular dentin. Intentionally worn areas inside each root were restored with a microhybrid light-cure composite resin (Z100) to reinforce them, with and without acid etching. Prefabricated metal posts were fixed with a dual resin cement (RelyX ARC), and the specimens were submitted to a pull-out test. Statistical analysis was performed by means of Shapiro-Wilk, analysis of variance (one-way ANOVA) and Tukey-Kramer tests (p<0.05). Results: The groups filled with Endofill (GI, GII, GIII, GIV) had the lowest bond strength values, which were similar among each other (p>0.05).The greatest bond strength values were observed in roots filled with AH Plus (GV, GVI, GVII, GVIII), mainly without cleaning of the weakened areas, and followed by acid etching (GVII), and also with cleaning of the weakened areas, however, with no acid etching (GVI) (p<0.05). Conclusion: The greatest bond strength values were observed in roots filled with AH Plus; (1) without cleaning of the weakened areas and with acid etching, and; (2) with cleaning of the weakened areas, but without acid etching.
