“…(7,8,9) MTA has been successfully used as an apical barrier. (10,11) In this case maintaining sterilization of root canal, intracanal medicament, good apical seal using MTA and a three dimensional obturation has contributed to the success of the cases.…”

“…Los componentes principales de MTA incluyen silicato tricálcico, aluminato tricálcico, óxido tricálcico y óxi-do de silicato (10). Este material cuenta con muchas ventajas como la aplicación en una sola cita, el sellado apical que favorece la regeneración ósea y menos porcentaje de fracturas, también cuenta con algunas desventajas, entre las que encontramos: dificultad de preparación del material, de manejo e introducción en el conducto radicular, sobre todo en los dientes largos y estrechos, la posibilidad de sobreobturación, el alto costo del producto y la producción de cambios excesivos de coloración a nivel coronal (11)(12)(13). Teniendo en cuenta esto, diversos materiales se emplean en un intento de reforzar esta zona y recuperar la estética del diente, incluyendo compuesto reforzado con resina de cemento de ionómero de vidrio, los postes, la raíz monobloque y las carillas de porcelana (14).…”

Manejo estético y endodóncico de dientes con formación radicular incompleta AVANCES EN ODONTOESTOMATOLOGÍA/201 RESUMENLa necrosis pulpar es una de las principales complicaciones de los traumatismos dentales lo que implica en un diente inmaduro la interrupción de la maduración de la raíz y el cierre apical. Una terapia llamada "apexificación" se requiere para inducir la formación de una barrera calcificada apical permitiendo un relleno permanente y hermético de la raíz. Numerosos materiales han sido recomendados para inducir apexificación y conservar la estética en dientes con ápices inmaduros como el mineral trióxido agregado (MTA), el hidróxido de calcio [Ca (OH)2], los postes de fibra de vidrio y entre los diversos materiales utilizados en prótesis, la cerámica que reproduce la apariencia de la dentición natural y tiene un comportamiento óptico muy similar a la de los tejidos duros dentales. El presente caso reporta paciente masculino de 17 años de edad con fractura coronaria complicada, conducto radicular expuesto a cavidad oral con formación radicular incompleta. El objetivo del presente caso clínico es describir la apexificación como primera alternativa para mantener un diente útil, utilizando la formación de una barrera apical con mineral trióxido agregado (MTA) y recuperar la estética del paciente. Conclusiones: La medicación intraconducto adecuada para la inducción a la formación de un cierre apical en un diente inmaduro o con formación radicular incompleta, es de trascendental importancia para el éxito del proceso de apexificación en donde juega un papel importante el MTA ya que en la actualidad es el material que brinda más ventajas en esta práctica como inductor de dicho proceso.Palabras clave: Apexificación, MTA, trauma dental, odontología cosmética, diente inmaduro. SUMMARYPulpal necrosis is one of the main complications of dental trauma which implies an interruption of the root maturation and the apical closure of an immature tooth. Apexification is a therapy used for inducing the creation of an apical calcified barrier allowing a permanent filling of the root. Several materials have been recommended to induce apexification and preserve aesthetics in teeth with immature apex, such as mineral trioxide aggregate (MTA), calcium hydroxide [Ca (OH)2], glass fiber posts, as well as the different materials used in prosthetic dentistry, ceramics that reproduce the appearance of the natural dentition and show an optic behavior very similar to the hard tissues of the teeth. This case reports a 17 year old male patient with a complicated crown fracture, exposed root canal in the oral cavity with incomplete root formation. The purpose of this clinical case is to describe the use of apexification as the first choice to keep a useful tooth, using the formation of an apical barrier with mineral trioxide aggregate (MTA) and recover the patient aesthetics.

“…18 Glass fiber posts are an alternative for the restoration of teeth with IR due they have modulus of elasticity similar to dentine. 19,20 The use of an apical plug with MTA has been suggested for endodontic therapy of teeth with IR, [21][22][23] resulting in a faster treatment and inducing the mineralized tissue formation in the root apex. 24 The root canal filling using Epiphany/…”

“…15,[21][22][23][24]37 The greatest fracture strength in this group could be related to the low elasticity modulus of glass fiber post promoting load distribution along the post length. 38 GII (positive control without preparation of the dentine walls) exhibited fracture strength smaller than GIII, and greater than GI and GIV.…”

Aim: The aim of this study was to evaluate the fracture strength (FS) of bovine incisors with simulated incomplete rhizogenesis (IR) after different intraradicular treatments. Materials and methods:Incomplete rhizogenesis was simulated by sectioning the crowns and roots of 40 bovine incisors. Root canal preparation was performed and the samples divided into 4 groups (n = 10): GI-negative control with intra-radicular preparation; GII-positive control without intra-radicular preparation; GIII-glass fiber post cemented with resin cement and GIVroot canal obturation with Epiphany/Resilon system. In GIII and GIV, 4.0 mm apical plugs of mineral trioxide aggregate (MTA) were done. The samples were embedded into cylinders with polystyrene resin, and the periodontal ligament was simulated with a medium-viscosity polyether-based impression material (Impregum Soft). The specimens were submitted to compressive fracture strength test (0.5 mm/min at 135º in relation to the long axis of the tooth) in a mechanical testing machine MTS 810. Data were submitted to ANOVA and Tukey's test (α = 0.05).Results: GIII produced the highest FS values (p < 0.05). GI and GIV showed similar FS results (p > 0.05) but smaller than GII (p < 0.05). Conclusion:Glass fiber intraradicular posts provided the FS increase of teeth with simulated incomplete rhizogenesis. Epiphany/Resilon root canal filling with MTA plug did not provide the increase of the fracture strength to teeth with simulated incomplete rhizogenesis. Clinical significance:The fiber post reinforces the root structure of teeth with incomplete rhizogenesis.
