“…Another possible explanation for this as stated by Daneshkazemi et al (2016) might be the presence of residual oxygen by-products have inhibited the polymerization of CC. Previous studies have showed both similar ( Pyun et al, 2016 , Daneshkazemi et al, 2016 ) and contrary results ( Monticelli et al, 2006b , Yenisey and Kulunk, 2008 , Monticelli et al, 2006c , Vano et al, 2006 ). HPSBS group had the lowest bond strength, although SEM showed increased surface roughness as shown in Fig.…”

“…FP and CC are usually used due to esthetic, easily placement and removal, minimal requirement of tooth structure removal, have a modulus of elasticity similar to dentin ( Aksornmuang et al, 2004 , Asmussen et al, 1999 ), single-visit and cost-effective procedure ( Bitter and Kielbassa, 2007 , Shori et al, 2013 , Pyun et al, 2016 ). A low incidence of root fracture and more repairable situations in the instance of failure have been reported with FP and CC system, which subsequently increase the survivability of the tooth as compared to cast post and core or zirconium posts ( Martinez-Insua et al, 1998 , Mannocci et al, 1999 , Akkayan and Gülmez, 2002 , Ferrari et al, 2000b , Ferrari et al, 2000a , Sarkis-Onofre et al, 2014 , Malferrari et al, 2003 , Cagidiaco et al, 2008 , Monticelli et al, 2008 , Yavirach et al, 2009 ).…”

Purpose To assess the impact of different surface treatments on the push-out bond strength between fiber post and a composite resin core material. Material and methods Seventy-two glass-fiber posts were randomly assigned into six groups according to the method of surface treatment: Control (no treatment), silane, sandblasting, hydrofluoric acid, hydrogen peroxide, and hydrogen peroxide with sandblasting. Two posts from each group were inspected under a scanning electron microscope to assess the surface modifications and 10 posts were employed for the push-out test. Each post was placed vertically in the middle of a cylindrical putty matrix and a dual-cure composite resin material was applied for core build-up. Two discs of each specimen were cut using a low-speed diamond saw (total 120 discs). The push-out test was executed using a universal testing machine at a crosshead speed of 0.5 mm/min. Statistical analysis was performed using one-way ANOVA and Tukey’s test ( p ≤ 0.05). The mode of failure of each disc was evaluated under SEM. Results The sandblasting and hydrofluoric acid groups presented significantly higher bond strength than control and hydrogen peroxide groups. The hydrogen peroxide groups exhibited significantly the lowest bond strength of all groups. There was no significant difference between the control and silane groups. All groups showed predominantly adhesive failure except the hydrogen peroxide with sandblasting, where the cohesive failure of the post was predominant. Conclusions Sandblasting and hydrofluoric acid surface treatments demonstrated superior results to silane and hydrogen peroxide. The combined method of hydrogen peroxide and sandblasting could weaken the fiber post and lead to clinical fractures.

“…Otro estudio únicamente utilizó la silanización para demostrar que esta incrementa la resistencia a la tracción del perno en 15,3MPa. (27), mientras que Puyn et al emplearon calor (80°C) después de la silanización, demostrando que este proceso incrementa la adhesión y que el uso de peróxido de hidrógeno no afecta en dicho proceso (19), al igual que lo probado por Samimi (24).…”

“…El empleo de pernos de fibra ha aumentado en la última década (11) dado que proveen buenos resultados estéticos y adecuada distribución de las fuerzas (14). Esto se debe a que su módulo de elasticidad es muy similar al de la dentina, por lo cual el riesgo de fractura de la raíz disminuye (19); sin embargo, uno de los problemas a largo plazo es el fracaso en la adhesión, la cual se puede dar por la desunión entre el perno y el agente cementante o, también, entre la dentina y el agente cementante, la que con frecuencia se produce por la fuerza de tracción (3,11,19).…”

“…Varios tratamientos de superficie tanto químicos como mecánicos (16) se han propuesto para los pernos de fibra a los largo del tiempo, los cuales buscan mejorar la adhesión de los pernos a la estructura dental y de esta forma mejorar los tiempos de vida útil de los mismos. Algunos de estos tratamientos son: enarenado utilizando partículas de óxido de aluminio en diversos grosores, silanización, peróxido de hidrógeno, ácido fluorhídrico, ácido ortofosfórico, ácido cítrico incluso tratamiento con láser (1,2,4,11,14,19,9,20,21,22). Estos pretenden aumentar la microrrugosidad del perno, aumentar el área superficial para la adhesión química; empero, también se exponen las fibras del perno alterando sus propiedades (11,19,13,14,15).…”

Objetivo: identificar tanto el tratamiento de superficie de pernos de fibra como el irrigante radicular idóneos para conseguir una cementación adecuada; así como conocer cuál es el tratamiento de superficie que produce menos desintegración de las fibras del perno de fibra. Materiales y métodos: se incluyeron 47 artículos publicados en inglés, durante los últimos 20 años, teniendo en cuenta que los mismos se obtuvieron hasta octubre del 2018. Conclusiones: previa la cementación de pernos sean estos de fibra o de cuarzo es indispensable realizar tratamiento de superficie para así mejorar la adhesión, estos pueden ser químicos o físicos, los que ofrecen mejor resultado sin alterar de manera significativa la estructura del mismo es el enarenado con partículas de diamante sintéticas de 1-3 µm seguido de silanización y dentro de los químicos H2O2 al 10% por 1 min seguido de silano. Para obtener mejores resultados se debe accionar el silano a una temperatura de 80°C. En cuanto a protocolos de irrigación depende del sistema de cementación que se vaya a emplear EDTA 18% + Hipoclorito de sodio al 5,25% o EDTA 18% + clorhexidina al 2% cuando se va emplear un cemento autoadhesivo y NaOCl al 11% cuando se utilice el acondicionamiento ácido de lavado y secado.Palabras clave: perno; endodóntico; preparación del diente; irrigantes del conducto radicular; EDTA.ABSTRACT Introduction: nowadays the aim is to keep the dental organ in function as long as possible, in many cases the endodontic treatment is used to preserve the dental pieces; and the use of fiber post when the coronary remnant is not adequate to receive a crown prosthesis, allowing us in these cases rebuilt the thoot for the subsequent placement of the final restoration.

This paper focuses on the study of the effect of modification of Oil Palm Empty Fruit Bunch (OPEFB) and sugarcane bagasse (SCB) biomass as potential reinforcement for composites panel and thermal insulation. Both fibres H₂O₂ and 4% H₂O₂-2% silane for 3 h. The influence of modified fibres content in composites was examined by structural changes using image analyser, Fourier transform infrared (FTIR), Scanning Electron Microscopy (SEM), tensile, interfacial shear strength (IFSS) and thermal characteristic. The diameter of both fibres was reduced after treatment and showed decreasing of lignin and hemicellulose in fibre. Tensile strength has been increased by 2% silane treatment for both fibres and 4% H₂O₂ treatment displays higher result for IFSS. Thermal properties of treated SCB fibre with silane display higher residual content and better thermal stability. SEM characterization showed that 2% silane treatment removed silica bodies of OPEFB fibre while 4% H2O2 treatment uniformly filled porosity of SCB fibre. Finally, results revealed that treated OPEFB fibre is enough to improve compatibility and mechanical properties, while treated SCB fibre was effective in thermal stability for fabrication of composite materials.
