          Abstract

          RESUMEN La longevidad del tratamiento restaurador indirecto en dientes con tratamiento endodóntico depende de varios factores. Siendo un factor muy importante, la cementación del retenedor intrarradicular. El objetivo de este artículo fue realizar una revisión de literatura sobre los aspectos relevantes para el éxito clínico en la cementación adhesiva de los pernos prefabricados. Se abordaron los siguientes temas: material de los pernos prefabricados, tratamientos de superficie, soluciones de irrigación utilizadas para la limpieza del conducto radicular y sistemas adhesivos. Se realizó una búsqueda bibliográfica de los últimos 5 años, en portugués e inglés, utilizando las bases de datos: Pub Med y BIREME. Del total de artículos obtenidos se seleccionaron los artículos con vinculación directa al tema, resultando en 40 publicaciones científicas. Se concluyó que la aplicación de silano y la silanización térmica aumenta la fuerza de unión entre el perno de fibra y el agente cementante. El hipoclorito de sodio al 2.5% no interfirió en la fuerza de unión de los pernos de fibra cuando se usa la técnica de ácido total junto con cemento resinoso de polimerización dual. Los adhesivos autograbantes se han mostrado prometedores, especialmente cuando se combinan con cementos autopolimerizables.

          ABSTRACT The longevity of indirect restorative treatment in teeth with endodontic treatment depends on several factors. A very important factor is the cementation of the intraradicular retainer.The aim of this study was the relevant aspects for clinical success in the adhesive cementation of fiber posts. The following topics were developed: fiber post material, surface treatments, irrigation solutions used for root canal cleaning, and adhesive systems. A bibliographic search of the last 5 years was carried out, in Portuguese and English, using the databases: PubMed and Bireme. From the total of articles obtained, articles with direct link to the topic were selected, resulting in 40 scientific publications. It was concluded that: the application of silane and thermal silanization increases the bond strength between the fiber bolt and the cementing agent. The 2.5% sodium hypochlorite did not interfere with the bond strength of the fiber bolts when the total acid technique is used in conjunction with dual-set resinous cement. Self-etching adhesives have shown promise, especially when combined with self-curing cements.

          A systematic review of factors associated with the retention of glass fiber posts

          This study aimed to identify factors that can affect the retention of glass fiber posts to intra-radicular dentin based on in vitro studies that compared the bond strength (BS) of GFPs cemented with resin cements. Searches were carried out in PubMed and Scopus until December 2013. Bond strength values and variables as type of tooth, presence of endodontic treatment, pretreatment of the post, type of bonding agent (if present), type of cement and mode of cement application were extracted from the 34 included studies. A linear regression model was used to evaluate the influence of these parameters on BS. The presence of endodontic treatment decreased the BS values in 22.7% considering the pooled data (p = 0.013). For regular cement, cleaning the post increased BS when compared to silane application without cleaning (p = 0.032), considering cleaning as ethanol, air abrasion, or phosphoric acid application. Applying the cement around the post and into root canal decreased the resistance compared to only around the post (p = 0.02) or only into root canal (p = 0.041), on the other hand, no difference was found for self-adhesive resin cement for the same comparisons (p = 0.858 and p = 0.067). Endodontic treatment, method of cement application, and post pretreatment are factors that might significantly affect the retention of glass-fiber posts into root canals mainly when cemented with regular resin cement. Self-adhesive resin cements were found to be less technique-sensitive to luting procedures as compared with regular resin cements.

              Push-out bond strengths of different dental cements used to cement glass fiber posts.

              Since the introduction of glass fiber posts, irreversible vertical root fractures have become a rare occurrence; however, adhesive failure has become the primary failure mode.
