“…Dessa forma, concluiu-se que o uso de pinos de fibra de vidro aumentou a resistência à fratura de dentes anteriores tratados e restaurados endodonticamente. Silva et al (2021) realizaram uma revisão de literatura com o intuito de avaliar o desempenho de pinos de fibra de vidro pré-fabricados com e sem customização quanto a resistência à fratura em dentes anteriores com canais alargados. A busca foi feita em 6 bancos de dados científicos (PubMed, Scopus, LILACS, SciELO, Science Direct e Web of Science) e três bases de dados (Open Gray, Open Thesis e OATD).…”

“…Para canais radiculares alargados, verificou-se que pinos de fibra de vidro modelados em CAD/CAM melhoraram significativamente a resistência à fratura em comparação ao uso de pinos de fibra de vidro pré-fabricados (PANG et al, 2019). No entanto, uma revisão de literatura apontou que os pinos de fibra de vidro modelados em CAD/CAM apresentaram desempenho similar aos pinos de fibra de vidro pré-fabricados no que diz respeito à resistência à fratura (SILVA et al, 2021).…”

Dentes com grande destruição coronária e tratados endodonticamente necessitam da utilização de retentores intrarradiculares para poderem ser restaurados e restabelecidos. No mercado, existem alguns exemplos de retentores intrarradiculares, e esses materiais são os metálicos, cerâmicos e os reforçados por fibras (carbono, vidro e quartzo). O pino de fibra de vidro se destaca, pois possui propriedades semelhantes à dentina. Neste contexto, o presente estudo teve por objetivo avaliar o desempenho do pino de fibra de vidro, verificando suas taxas de sobrevivência e resistência à fratura. Foram utilizadas revisões sistemáticas e estudos clínicos publicados nas bases eletrônicas de dados científicos. Em geral, os pinos de fibra de vidro apresentaram desempenho similar aos núcleos metálicos fundidos, sendo considerados uma alternativa viável e eficaz para a restauração de dentes tratados endodonticamente, especialmente em áreas anteriores, nas quais há maiores exigências estéticas. O desempenho do pino de fibra de vidro foi considerado semelhante ao núcleo metálico fundido no que se refere a resistência a fratura e taxa de sobrevivência em longo prazo, apresentando como vantagens o seu aspecto mais estético e um melhor módulo de elasticidade, além de menos incidência de falhas irreparáveis.

“…In a systematic review and meta-analysis, Silva et al . found no significant difference in fracture resistance of fiber posts reinforced with auxiliary fiber posts or composite resin and non-reinforced posts ( 12 ). The relining procedure of fiber post increases the cost of materials and clinical chair-time, so most clinicians may refuse to use these techniques due to the lack of significant improvement ( 12 ).…”

“…found no significant difference in fracture resistance of fiber posts reinforced with auxiliary fiber posts or composite resin and non-reinforced posts ( 12 ). The relining procedure of fiber post increases the cost of materials and clinical chair-time, so most clinicians may refuse to use these techniques due to the lack of significant improvement ( 12 ). Therefore, this study can be important because of the significant differences in fracture resistance between the experimental groups and the non-reinforced group.…”

Background This study is done to evaluate the effect of different reinforcement techniques of overflared root canals with fiber posts on the fracture resistance of endodontically treated anterior teeth. It also introduces a new technique for simultaneous reinforcement and cementation of fiber posts using dual-cured core build-up composite resin. Material and Methods The crowns of 48 single-rooted maxillary anterior teeth were cut and randomly divided into 4 groups (n=12) based on root reinforcement techniques after root canal treatment and post space preparation: Group 1: self-adhesive resin cement (SARC), Group2: dual-cure composite resin (DCC), Group3: Composite resin reinforcement (CRR), Group 4: Direct anatomical post (DAP). Then a core was made for the roots. The periodontal ligament was simulated using a thin layer of PVC impression material. A universal testing machine applied a compressive force to the lingual surface at an angle of 135 ° and 1 mm/min speed. Data were analyzed using One-Way ANOVA and a post-hoc Tukey test. Fracture patterns were analyzed using the Chi-square test ( p <0.05). Results The difference between the control and DAP group was statistically significant ( p =0.01), but there were no significant differences between other groups ( p >0.05). Regarding fracture patterns, there were no significant differences between groups. Conclusions All reinforcement techniques increased the fracture strength compared to the control group. However, DAP was the only group that had a statistically significant difference. CRR and DCC presented intermediate values without significant differences. Key words: Fiber post, endodontically treated teeth, root canals, reinforcement, fracture strength.
