“…1,2 The choice of materials used in these cases has changed from rigid materials, such as gold and zircon dioxide, to materials that have mechanical characteristics that more closely resemble dentin, such as fiber posts and composite resins. 3,4 Use of these materials diminishes the probability of root fracture, because these failures occur particularly in the post, allowing for tooth recovery. 5 The bonding performance of resin cements is dependent on the quality of the hybrid layer.…”

The use of self-adhesive resin cements is an option for bonding fiber-reinforced composite posts to root canal dentin. Traditional resin cements apparently provide higher bond strengths than self-etch resin cements. Because of this, the bond strength of self-adhesive resin cements to root dentin should be evaluated. SUMMARYObjectives: This study evaluated the bond strength of luting systems for bonding glass fiber posts to root canal dentin. The hypothesis tested was that there are no differences in bond strength of glass fiber posts luted with different cement systems.Methods: Forty bovine incisors were randomly assigned to five different resin cement groups (n=8). After endodontic treatment and crown removal, translucent glass fiber posts were bonded into the root canal using five different luting protocols (self-cured cement and etchand-rinse adhesive system; dual-cured cement and etch-and-rinse adhesive system; self-cured cement and self-etch adhesive system; dualcured cement and self-etch adhesive system; and dual-cured self-adhesive cement). Pushout bond strength was evaluated at three different radicular levels: cervical, middle,

“…41 The surface of fiber posts is so polymerized that they are no longer capable of reacting or bonding to free radicals. 42 The bond strength of composite resins to fiber posts is often limited due to chemical heterogeneity between methacrylatebased resins and epoxy resins in the post. 43 Also, the composition of resin polymer matrix in the post can affect the ability of adhesive to penetrate between the fibers and provide adequate micromechanical retention.…”

Bond Strength of Fiber Posts to Composite Core: Effect of Surface Treatment With Er,Cr:YSGG Laser and Thermocycling

et al. 2017

Introduction: This study aimed to determine the bond strength of fiber post to composite core following surface treatment with Er,Cr:YSGG laser at different powers and sandblasting with and without thermocycling. Methods: In this experimental study, 30 fiber posts (Glassix, Nordin, Switzerland) were randomly divided into 5 groups of sandblasting, no treatment and laser irradiation at 1, 1.5 and 2 W powers. Following composite filling and mounting, 1-mm thick sections were made for pushout bond strength testing. Half of the samples in each group were subjected to thermocycling (n=15). Two-way analysis of variance (ANOVA) was used to analyze the bond strength values. Pairwise comparisons were made using Tukey test (P < 0.05). Results: Effect of treatment method on push-out bond strength of fiber post to composite core was significant (P = 0.017), while thermocycling had no significant effect on bond strength (P = 0.964). Pairwise comparison of surface treatment methods revealed no significant difference in groups with and without thermocycling (P > 0.05), but Er,Cr:YSGG laser irradiation with 1 W power yielded significantly higher bond strength than the control group (P =0.01). Conclusion: Irradiation of Er,Cr:YSGG laser at 1 W power increased the bond strength of fiber post to composite core. Thermocycling slightly decreased the bond strength at the fiber postcore interface.

Ö ÖZ ZE ET T Çürük, travma, restorasyonlar, erozyon, atrizyon ve abrazyon gibi birçok faktöre bağlı olarak çok fazla madde kaybı olan ve endodontik tedavi sonrası daha da zayıflayan dişlerin nasıl restore edileceği her zaman bir sorun olmuştur. Endodontik tedavili dişlerin post ve kor sistemleri ile restorasyonu diş hekimliği pratiğindeki en riskli işlemlerden biridir. Endodontik tedavi geçirmiş bir dişin restoratif ve protetik tedavisi, kalan sağlıklı dokuların miktarına, uygulanan kor restorasyonunun prognozuna, kor yapısına destek olan post çeşidine ve post yüzeyine tutuculuğu artır-maya yönelik yapılacak işlemlere, restorasyonun genel olarak yapısal ve estetik kalitesiyle, klinik adaptasyonuna bağlıdır. Günümüzde estetik beklentilerin artması ve adeziv sistemlerin gelişme-siyle birlikte post kor sistemlerinin seçenekleri artmıştır. Giderek artan estetik ve biyolojik olarak uyumlu maddelere olan talep, metal olmayan post kor sistemlerinin geliştirilmesine yol açmıştır. Fiberle güçlendirilmiş sistemler daha çok kullanılmaya başlamıştır. Bu derlemede, restorasyonların ağızda kalma oranı ve en yaygın başarısızlık tipleri açısından, döküm post kor ve fiber postlar ile ilgili retrospektif ve prospektif klinik çalışmalar gözden geçirildi. Buna ilave olarak yüzey işlemleri-nin post sistemlerinin retansiyon başarısı üzerine etkileri ve yeni bir post kor sistem olan yüksek performanslı polimer PEKK (polyetherketoneketones)'in üzerinde durulmuştur. Bu derlemenin amacı; madde kaybı çok fazla olan endodontik tedavili dişlere uygulayacağımız tedaviye karar vermekte diş hekimlerine yardımcı olmaktır.A An na ah h t ta ar r K Ke e l li i m me e l le er r: : Post-kor tekniği; endodontik tedavi görmüş dişler; literatür gözden geçirme; karbon fiberle güçlendirilmiş; cam fiber; polietereterketon; yüzey işlemleri A AB BS S T TR RA AC CT T It has always been a problem to restore teeth that have lost too much tissue due to many factors such as caries, trauma, previous restorations, erosion, attrition and abrasion, and even weakened after endodontic treatment. The restoration of endodontically treated teeth with postcore systems is one of the most risky procedure in dental practice. Restorative and prosthetic treatment of a tooth that has undergone endodontic treatment generally depends on the amount of remaining healthy tissue, the prognosis of the applied core restoration, and the clinical adaptation of the restoration with structural and aesthetic qualities. Nowadays, with the increase of aesthetic expectations and the development of adhesive systems, the choice of post-core systems has increased. Demand for increasingly aesthetically and biologically compatible materials has led to the development of non-metallic post-core systems. Fiber-reinforced systems have started to be incorporated into routine clinical care more frequently. In this survey, retrospective and prospective clinical studies dealing with cast-post-and core and fiber posts were reviewed regarding the rate of survival of restorations and the most prevalent failur...
