    Irrigación en endodoncia: Puesta al día
    (2013) Raúl Miliani; Kelly Lobo; Óscar Alberto Morales
    La irrigacion en endodoncia se define como la introduccion de una o mas soluciones en la camara pulpar y conductos radiculares antes, durante y despues de la preparacion biomecanica para desinfectar y limpiar el sistema de conductos y garantizar el exito del tratamiento. Sin embargo, hasta ahora ninguna de las sustancias utilizadas en endodoncia con este fin cumple con los requisitos ideales. Aunque en la actualidad el MTAD es considerada la sustancia clinicamente mas efectiva y biocompatible, todavia hay controversia. Por lo tanto, el objetivo de este estudio es determinar la efectividad de los irrigantes mas utilizados, con base en una revision actualizada de la literatura. Se realizo una busqueda en Medline, LILACS, Elsevier, SCielo, JoE, IsDR, Saber ULA y Google Academico, de articulos publicados en ingles y espanol entre 2006 y 2012, utilizando los descriptores Irrigacion, EDTA, Hipoclorito de Sodio, Clorhexidina y MTAD. No se encontro un irrigante totalmente efectivo: ser antibacteriano, eliminar el desecho dentinario y ser lubricante a la vez. Sin embargo, el NaOCl es la sustancia que se utiliza con mayor frecuencia por su propiedad antibacteriana. Finalmente, se sugiere el uso combinado de los cuatro irrigantes estudiados para garantizar su efectividad.

    Sistemas portaper, k3 y profile para la preparación de conductos radiculares: revisión actualizada
    (2013) Kelly Lobo; J Torrecilla Cañas; Óscar Alberto Morales; Rita Gutiérrez; Raúl Miliani
    In Endodontics, the technology has been giving multiple proposals in recent years, always with the aim of enabling the clinical success. Specifically, it allows a root canal treatment to provide an effective cleaning, shaping, sealed, using a simple, quick and convenient method for both the operator and patient. Many root canal preparation systems have been widely studied. However, the revision of the literature suggests that there is not a document that collects this information. Therefore, this article descibe the effectiveness of three root canal preparation systems, Protaper, K3 and Profile. This will allow the clinicians and students, the appropriate selection and use of these systems of preparation, as they are the most widely used and recommended nowadays. To achieve this purpose, it conducted a systematic review of the literature in electronic and printed media related to the above mentioned systems. We find that the Protaper system is more effective to prepare root canals with high effectiveness of cut, resistance to cyclic fatigue and does not create apical transportation thus maintaining the integrity of the canal, K3 only confers resistance to fatigue and flexibility in their instruments thus becoming the second option at the time of choosing an Instrumentation System and only Profile has cut effectiveness propiety, which makes it less quality in comparison with the two systems mentioned above. This could encourage and stimulate students and dentists in training, to carry out studies of cut qualitative to explore with greater depth, all mechanical systems mentioned and their direct influences on the root canal anatomies of each dentary group.
