“…Surface treatments can be chemical treatment, surface roughening, and a combination 4 surface treatment with silane-coupling agents improves the bond strength by 20%. 5 It mediates adhesion between inorganic and organic matrices by the formation of siloxane bonds, which makes the surface less polar and hence more compatible to bonding with adhesive resin.…”

“…Surface roughening treatment with sandblasting procedure improves the bond strength by 19%. 5 Sandblasting roughens the surface of the fiber post, thereby promoting the larger surface area for bonding, which creates a mechanical interlock with the resin cement. Combination-surface treatment with sandblasting followed by silanization improved the bond strength by 50%.…”

Introduction: For the restoration of grossly decayed root canal treated teeth, posts are used frequently to retain core for the definitive restoration. Therefore, it is necessary to create adequate adhesion at the post-root-cement interface for long-term performance of a post retained restoration. Aim: To establish the outcome of surface pretreatments such as silanization, sandblasting, and silanization followed by thermal activation of fiber posts on bonding with a dual-cured adhesive resin-based cement. Materials and methods: Eighty radiopaque, No #2 glass fiber-reinforced epoxy resin posts (Hi-Rem Posts, Overfibers, Switzerland), posts were wiped with alcohol (surgical spirit, 90% alcohol) for 5 seconds in a single stroke. A cylindrical plastic cap of diameter 10 mm and length of 15 mm, which is closed on one side, was selected. This was duplicated to form molds and fiber posts embedded perpendicularly in the polyester resin, and samples were made. Samples were randomly distributed into four groups based on the pretreatment done and each group contains 20 samples, group I-(control), group II-(silanization), group III-(sandblasting), and group IV-(thermal treatment of silane). After surface treatment, exposed post surface was uniformly coated with dual-cured resin cement. Cement was cured for 40 seconds with a halogen lamp. The samples are subjected to load in a universal testing machine (UTM) at a crosshead speed of 1.0 mm/minutes to evaluate the bonding failure at the interface. Results: Group IV resulted in the highest bond strength values followed by group III. Group II showed a comparatively higher value than group I but less than groups III and IV. Conclusion: Surface treatment procedure, on fiber post by silanization and sandblasting significantly improved adhesion between post and luting cement interface. Clinical significance: The surface pretreatment, such as sandblasting, silanization, thermal activation of silane coupling agents significantly improved, the retention of the post within in the root canal system.

“…Dessa forma, tem a capacidade de aumentar a molhabilidade do composto resinoso aplicado a superfície do pino. 7,10,12,13 O ácido fluorídrico é comumente utilizado para o tratamento de superfície de cerâmicas, pois este procedimento, seguido da aplicação de silano, produz união clinicamente aceitável da resina composta para cerâmica à base de Sílica 7,11,13,14 . Por outro lado, foi constatado que o ácido fosfórico, quando empregado como método de tratamento de superfície, proporciona pouca alteração superficial na estrutura dos pinos de fibra de vidro, atuando de maneira mais eficiente na limpeza superficial do mesmo…”

| Objective: The objective of this workwas to evaluate the influence of different methods of surface treatment on glass fiber posts with respect to their bond strength with the composite resin. Method: Twenty-four pre-fabricated posts were randomly divided into three groups (n= 8) according to the chosen surface treatment. Control Group-surface treatment with 37% phosphoric acid etching and silanization. Group 2 -conditioned with 10% fluoridric acid and silanization. Group 3 -sandblasting for 10 seconds and silanization. The specimens were obtained using the stainless steel matrix made for this study and were maintained in absolute humidity at 37 ° C for 48 hours and then subjected to the PUSH-OUT test on the test machine. Results: The results showed that the aluminium oxide blasting treatment of aluminum and silane (12.24 MPa) (G3) had statistically significant difference when compared to the treatment of hydrofluoric acid and silane (G2) (8.03 MPa) (p <0, 05). The predominant fracture type was cohesive of the composite resin (68.75%) and only a mixed fracture (2.08%) was observed. Conclusions: Thus, it is concluded that the blasting treatment of aluminum oxide and silane can be used as a surface treatment on the glass fiber post.

Objetivo: O objetivo deste trabalho foi avaliar a influência de diferentes métodos de tratamento da superfície em pinos de fibra de vidro com relação à sua força de união com a resina composta. Metodologia: Foram utilizados vinte e quatro pinos pré-fabricados e divididos aleatoriamente em três grupos (n=8) de acordo com o tratamento de superfície escolhido. Grupo Controle- tratamento de superfície com condicionamento ácido fosfórico a 37% e a silanização. Grupo 2 – condicionados com ácido fluorídrico a 10% e silanização. Grupo 3 - jateamento com óxido de alumínio por 10 segundos e silanização. Os corpos-de-prova foram obtidos com a utilização da matriz de aço inoxidável confeccionada para este estudo e foram mantidos em umidade absoluta a 37°C durante 48 horas para, então, serem submetidos ao teste de PUSH-OUT na máquina de teste. Os resultados foram avaliados pelo teste de Tukey com significância de 5%. Resultados: Os resultados demostraram que o tratamento de jateamento de óxido de alumínio e silano (12,24 MPa) (G3) apresentou diferença estatisticamente significante comparado com o tratamento de ácido fluorídrico e silano (G2) (8,03 MPa)(p<0,05). O tipo de fratura predominante foi coesiva da resina composta (68,75%) e apenas uma fratura mista (2,08%) foi observada. Conclusão: Dessa forma, conclui-se que o tratamento de jateamento de óxido de alumínio e silano pode ser utilizado como tratamento de superfície nos pinos de fibra de vidro.
