Abstract
ResumenEl agregado de trióxido mineral (MTA) es un material desarrollado para endodoncia. Las principales indicaciones del MTA, son el tratamiento pulpar en dientes vitales (pulpotomias, recubrimiento pulpar directo), apicoformaciones (barrera apical), cirugía endodóncica, reparación de perforaciones furcales, laterales y las provocadas por las reabsorciones. El MTA favorece la formación de hueso y cemento, y puede facilitar la regeneración del ligamento periodontal sin provocar inflamación; como un coadyuvante del MTA en los procesos de reparación tenemos el hidróxido de calcio que es un potente agente bacteriostático y bactericida que se utiliza para el control de microorganismos cuando es empleado como medicamento intraconducto, igualmente actúa como agente catalizador en la modificación del pH en los tejidos periapicales con el fin de favorecer el proceso de cicatrización, presenta excelentes propiedades higroscópica en cuanto al control del exudado en conductos radiculares de dientes con lesiones periapicales grandes los cuales muchas veces presentan humedad persistente en los canales radiculares asimismo actúa en la prevención o detención de procesos resortivos ejerciendo efectos moduladores en la actividad clástica. Por tales propiedades el artículo tiene como fin mostrar los efectos a corto plazo que ocurren en una reabsorción interna y lesión apical al momento de utilizar mineral trióxido agregado (MTA) e hidróxido de calcio como material intracanal.

The principal indications of MTA are vital pulp therapy (pulpotomy, direct pulp capping), apexification (apical plug), endodontic surgery, and lateral, furcal and resorption perforations repair. The MTA induce the formation of cementum and bone, and it may facilitate the regeneration of the periodontal ligament without causing any inflammation; as a helping of the MTA in the repair processes we have the bactericidal calcium hydroxide which is a powerful bacteriostatic agent and it is used for the control of microorganisms when is placed as a canal medication, also acts like catalytic agent in the modification of the pH in periapicals tissues with the purpose to favor the healing process, presents excellent higroscopic properties in the control of the exudates in root canals of teeth with great periapical injuries which often present persistent humidity in the root canals and also acts in the prevention or halting of resorptives processes exerting effects modulators in the clástica activity. The purpose of this article is to show the short term effects that happen in an internal resorption and apical injury at the time of using mineral trioxide aggregate (MTA) and calcium hydroxide as a root canal medication.Key words: Mineral trioxide aggregate; calcium hydroxide; endodontics; microorganisms; Internal root resorption; apical lesion; root canal treatment.References
