“…16 Furthermore, fiber-reinforced posts do not result in metal corrosion or allergic reactions and can be easily removed from a root canal when failure occurs due to endodontic treatment. 17,18 Due to the increased interest in fiber-reinforced posts in the dental literature, studies have focused on post materials, 19 luting agents, 20 post designs, 21 and ferrule effects to investigate the fracture resistance of these materials. 22 However, those studies produced conflicting results.…”

Background/purpose: The aim of this study was to determine and compare the fracture resistance of endodontically treated teeth restored with or without posts. Materials and methods: Undamaged, extracted human premolar teeth (48 in total) were randomly divided into four groups of 12 each. Clinical crowns of the teeth were cut 3 mm coronal to the cementoenamel junction. Root canals were enlarged using rotary canal instruments (Dentsply) and filled with gutta-percha (Dentsply) as well as a sealer (AH 26, De Trey). In all groups, gutta-percha was removed, and the post space was prepared using tapered drills (FRC Postec post kit, Ivoclar Vivadent). The first group of fiber-reinforced composite posts (FRC Postec Plus, Ivoclar Vivadent) and the second group of Ever Stick posts (Stick Tech) were luted into the root canals using dual curing resin cement (Variolink II, Ivoclar Vivadent). In the third group, post spaces were filled using a hybrid resin composite (Tetric Evo Ceram, Ivoclar Vivadent). The fourth group served as a control with direct resin composite core reconstruction formed without a post. Composite cores were constructed with a hybrid resin composite (Tetric Evo Ceram, Ivoclar Vivadent) in all groups. Fracture loading was accomplished using an universal testing machine at a crosshead speed of 1 mm/min in compression mode. Results: There were no statistically significant differences between the fracture resistance values for the four experimental groups (P > 0.05). Conclusions: Fiber-reinforced posts can be used as a core material in endodontically treated teeth as well as composite core reconstructions.

Fibre-based post systems: a review

Objectives This article presents a review of published literature examining fibre-based endodontic post systems. Data sources A MEDLINE search was carried out for any articles in dental journals pertaining to fibre-based post systems. Wherever possible articles cited were obtained from the journals and where this was not possible abstracts were obtained. Where no abstract was available the article was not considered for evaluation. Data extraction Articles were reviewed by a single observer and subject to meeting inclusion criteria were included in the review. Fifty-nine articles were considered suitable for inclusion. Data synthesis Articles were divided into categories and a subjective description of the articles was made. Conclusions Review indicated that (1) most published literature on fibre-based posts took the form of laboratory analyses; (2) evidence for carbon-fibre posts far exceeds that for quartz-fibre posts; (3) laboratory evidence was contradictory and could not be used to inform practice reliably; (4) few clinical studies have been carried out though these have suggested fibre based posts may be clinically appropriate for restoration of the endodontically treated tooth; and (5) controlled prospective clinical trials evaluating fibre-based posts should be undertaken to inform use for clinical practice.

AbstractSeveral researchers afirm that the posts provide support to the final restoration of teeth with endodontics, the evolution of these has gone from posts of wood to fiberglass posts. This review of the Literature was made on several databases using the keywords "post core technique, endodontics". We analyze bibliographic information related to the evolution of the origin of the posts in order to update the knowledge regarding their use, choice and the respective rehabilitation. Introducción Antiguamente, se pensaba que el uso de los postes servía para dar fuerza a la raíz despulpada, debido a su deshidratación y pérdida de sustancia dentinaria. Con el paso del tiempo, la tecnología, los avances científicos y los numerosos estudios de investigación, han hecho que esta afirmación cambie, debido a los persistentes fracasos en tratamientos con postes. Antes solo se podía hacer uso de los postes colados hechos de materiales que aparte de no ser estéticos, su alto módulo de elasticidad mayor a 200 GPa contribuía a la fractura radicular del órgano dentario. La incursión de los postes prefabricados de fibras de vidrio, carbono, cuarzo y sus distintas variaciones ha mejorado sus propiedades mecánicas, fí-sicas y estéticas de manera sustancial. Diversos reportes indican que las propiedades físicas y mecánicas de los postes de fibra presentan una mejor resistencia a la fractura radicular en comparación a los postes metáli-cos. Por este motivo es importante evaluar y considerar todos los factores necesarios para la elección de un poste adecuado dependiendo del caso. Este artículo pretende revisar la evolución del poste muñón con el fin de actualizar el conocimiento respecto a su uso. Keywords Materiales y métodoLa literatura fue revisada en todos los idiomas en diversas bases de datos como Pubmed, Medline, EBSCO y SciELO publicada en los últimos 30 años, usando las palabras clave: técnica de perno muñón y endodoncia tal como aparece en los descriptores en ciencias de la salud (DeCS). Se encontraron 150 artículos, de los cuales
