1. Can intra-radicular cleaning protocols increase the retention of fiberglass posts? A systematic review
Abstract The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review invo

2. Clinical performance and failure modes of pulpless teeth restored with posts: a systematic review
Abstract The aim of this systematic review was to compare the clinical performance and failure modes of teeth restored with intra-radicular retainers. A search was performed on PubMed/Medline, Central and ClinicalTrials databases for randomized clinical trials comparing clinical behavior and failures of at least two types of retainers. From 341 detected pape

3. 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 tr

4. Intra-radicular dentin treatments and retention of fiber posts with self-adhesive resin cements
The aim of this study was to evaluate the effect of treating intraradicular dentin with irrigating solutions on the retention of glass-fiber posts luted with self-adhesive resin cement. Bovine incisors were endodontically treated, and 9-mm-deep postholes were prepared. Before inserting the cement, the root canals were irrigated with various solutions: 11.5%

5. Influência de materiais obturadores e agentes de limpeza na resistência da união e interface adesiva de pinos de fibra de vidro à dentina intrarradicular / Influence of filling materials and cleaning agents on bond strength and adhesion interface of glass fiber post to radicular dentin
The aim of this in vitro study was to evaluate the post-cement-dentin adhesive interface quality and the effect of different filling materials and cleaning agents on the bond strength of glass fiber posts to primary root dentin. This study included 156 roots of bovine primary teeth which were endodontically treated and assigned to four groups (39 teeth each

7. Influência da espessura do filme de cimento na resistência adesiva de pinos de fibra de vidro cimentados em condutos radiculares de dentes humanos / Influence of the cement film thickness on the push out bond strength of glass fiber posts cemented in human root canals
O presente estudo visa avaliar a influência da espessura do filme de cimento sobre a resistência de união de pinos de fibra de vidro em diferentes regiões do conduto radicular (cervical, médio e apical), cimentados com cimento resinoso autoadesivo, com e sem a adição de Rodamina B, por meio do teste de push-out. Quarenta raízes foram incluídas em re

8. Tensile bond strength of metal posts after the application of Er:YAG laser treatment to the weakened root canal reinforced with composite resin / Avaliação ex vivo da resistência à tração, de pinos metálicos em raízes fragilizadas tratadas com laser Er:YAG e reforçadas com resina composta
O objetivo do estudo foi avaliar ex vivo a influência da aplicação do laser de Er:YAG na parede dentinária de raízes fragilizadas, reforçadas com resina composta. Cinquenta caninos superiores tiveram suas coroas removidas próximo da junção amelo-cementária e incluídas em bloco de resina acrílica. Após tratamento endodôntico foi realizada a frag
