“…[26][27][28][29] It is known that maximum load capability is affected less by post strength, but more by the amount of surrounding hard tissue. 17) These specimens are of sufficient tooth structures and height of coronal dentin as well as resin-reinforced dentin wall. For this reason, higher modulus of elasticity of titanium post does not increase fracture strength and the incidence of oblique root fracture.…”

The purpose of this study was to determine the effect of post types and sizes on fracture resistance in immature tooth model with various restorative techniques. Bovine incisors were sectioned 8 mm above and 12 mm below the cementoenamel junction to simulate immature tooth model. To compare various postand-core restorations, canals were restored with gutta-percha and resin core, or reinforced dentin wall with dual-cured resin composite, followed by placement of D.T. LIGHT-POST, ParaPost XT, and various sizes of EverStick Post individually. All of specimens were stored in the distilled water for 72 hours and underwent 6,000 thermal cycles. After simulation of periodontal ligament structure with polyether impression material, compressive load was applied at 45 degrees to the long axis of the specimen until fracture was occurred.Experimental groups reinforced with post and composite resin were shown significantly higher fracture strength than gutta-percha group without post placement (p < 0.05). Most specimens fractured limited to cervical third of roots. Post types did not influence on fracture resistance and fracture level significantly when cement space was filled with dual-cured resin composite. In addition, no statistically significant differences were seen between customized and standardized glass fiber posts, which cement spaces were filled with resin cement or composite resin individually. Therefore, root reinforcement procedures as above in immature teeth improved fracture resistance regardless of post types and sizes. [J Kor Acad Cons Dent 35(4):257-266, 2010]

“…In this regard, FRC posts seem to have advantages over ceramic and metal posts. In addition, reports exist indicating that the fracture resistances of endodontically treated teeth restored with FRC posts were similar, or even higher than those restored with ceramic and titanium posts 36,38,39) .…”

The aim of this study was to estimate the flexural properties of three kinds of experimental fiber-reinforced composite (FRC) posts and to evaluate their potential use as posts. Experimental FRC posts were fabricated with glass, aramid, and UHMWP fibers. Commercial FRC posts were used for comparison. A three-point bending test was performed at a crosshead speed of 1 mm/min. Experimental glass fiber posts showed significantly higher flexural strengths and moduli than aramid and UHMWP posts. Experimental UHMWP posts demonstrated superior toughness to the commercial posts. The glass fiber posts displayed stiff, strong and brittle features, while the UHMWP posts were flexible, weak and ductile. The flexural properties of the aramid posts fell between those of the glass and UHMWP posts. In conclusion, the glass fiber posts proved excellent in flexural strengths and moduli. However, the superior toughness of UHMWP fibers suggests the possibility of their use as posts in combination with glass fibers.

“…O papel do pino intra-radicular, qualquer que seja o material utilizado, é o de servir como suporte para a reconstrução coronária, sem nenhuma pretensão ou probabilidade de reforço da estrutura radicular remanescente (7,25,27,28 As variáveis biológicas e técnicas envolvidas no preparo intra-radicular são complexas. O uso de pinos não aumenta a resistência à fratura dos dentes restaurados, porém a quantidade de remanescente coronário influencia a estabilidade do conjunto (37).…”

“…O uso de pinos não aumenta a resistência à fratura dos dentes restaurados, porém a quantidade de remanescente coronário influencia a estabilidade do conjunto (37). Técnicas conservadoras de preparo, bem como manutenção da maior quantidade possível de remanescente coronário (efeito férula) são consenso entre os pesquisadores (28,33,37). A magnitude e direção das forças oclusais também são fatores que não devem ser subestimados (29).…”

RESUMOIntrodução: Atualmente, o conhecimento acerca da interação dos cimentos auto-adesivos com a dentina intra-radicular é escasso. Informações detalhadas sobre a linha de cimentação e a interação com o substrato podem trazer dados preciosos na busca de uma união mais efetiva. Objetivo: Analisar a linha de cimentação de três cimentos resinosos autoadesivos e um resinoso dual convencional em dentina intra-radicular, por meio de microtomografia e do teste de push-out. Método: Três cimentos auto-adesivos (U100/3M ESPE, Maxcem/Kerr, Clearfil SA Bond/Kuraray) e um cimento resinoso dual convencional (Rely X ARC/3M ESPE) foram testados usando 2 técnicas de cimentação. O percentual de bolhas e a resistência de união foram quantificados de acordo com a técnica e os terços. 40 raízes de pré-molares humanos foram desobturadas na profundidade de 10mm. O cimento resinoso foi manipulado de acordo com a recomendação do fabricante. A inserção do cimento seguiu as orientações dos fabricantes para os grupos A e, para os grupos B, 40 pinos de fibra foram cimentados com o auxílio da ponta agulha de uma seringa centrix. As raízes foram escaneadas em um microtomógrafo e a linha de cimento foi analisada pelos softwares DataViewer, CTan, CTvol e CTvox. Após 07 dias, as raízes foram seccionadas perpendicularmente ao longo eixo e submetidas ao teste de extrusão. Os dados foram submetidos a ANOVA 3 critérios e Teste de Tukey. Resultados e Conclusão: A análise microtomográfica mostrou menor número de bolhas para os grupos B. A resistência de união foi significativamente maior para os auto-adesivos quando a seringa centrix foi utilizada (p<0,0001). A resistência de união decresceu em direção apical, independentemente da técnica e da distribuição das bolhas. Não houve relação entre os valores de resistência de união e a localização e volume de bolhas. A microtomografia mostrou-se um método eficaz na visualização e quantificação de bolhas na linha de cimentação.
