Abstract
El agregado trióxido mineral (MTA) es un material que se ha consolidado para el tratamiento de numerosas patologías con necesidad de sellado endo-periodontal. Los MTA que llevan más tiempo comercializados son los de Dentsply y Ángelus. Existen diferencias entre los MTA de ambas empresas, destacando las referidas a composición y tamaño y forma de sus partículas de polvo. La extensión de su uso se ha basado en sus resultados de biocompatibilidad y capacidad de sellado. Sin embargo, es de difícil manejo y puede oscurecerse una vez fraguado. Son escasos los estudios que usan ultrasonidos en la adaptación del MTA-dentina, aunque podría ser un método sencillo para mejorar el sellado. El efecto que los ultrasonidos tendrían sobre el color del MTA no se ha estudiado todavía...
Mineral trioxide aggregate (MTA) is a material whose use has been consolidated in the treatment of numerous pathologies requiring endoperiodontal sealing. The MTAs that have been on the market for the longest period of time are produced by Dentsply and Angelus. Both companies’ MTAs differ, particularly in terms of their composition and the size and shape of their powder particles. Their degree of use has been based on their biocompatibility results and sealing capacity. However, this material is difficult to manipulate and may darken once it sets. Few studies using ultrasound in the MTA-dentin adaptation have been conducted, though it could prove a simple method for improving the sealing process.
