Resumen
Durante el transcurso del tiempo han sido usados diversidad de materiales para realizar la obturación radicular, tales como asbesto, yeso, metales preciosos, bambú, ionómeros de vidrio y resinas epóxicas; sin embargo, varios de estos materiales se han dejado de emplear, debido a que se han considerado como inaceptables biológicamente e imprácticos ya que pueden causar inflamación de los tejidos perirradiculares, lo que provoca sensibilidad dolorosa a mediano o largo plazo de haber finalizado el tratamiento endodóntico. El objetivo de esta investigación fue, analizar el daño producido en el ligamento periodontal al vincularse con los cementos de sellado radicular. La metodología utilizada fue de tipo documental, descriptiva, cualitativo, exploratorio. Los agentes citotóxicos que se encuentran en los selladores y las consecuencias de esta irregularidad en los tejidos periapicales, deben ser un referente para evitar terminantemente, la fuga transapical del cemento endodóntico al efectuar la obturación de conductos radiculares. En los resultados se obtuvo que todos los selladores utilizados en la endodoncia causan en menor o mayor grado citotoxicidad en los tejidos perirradiculares, por lo que es necesario aplicarlos de manera correcta para disminuir estos efectos indeseables. Se concluyó que aquellos selladores que poseen agentes antimicrobianos, son los que mayormente causan daños en los tejidos periapicales, produciendo efectos como inflamaciones, daños en el tejido fibroso conectivo, reabsorciones óseas y necrosis tisular, por lo tanto se recomienda limitar la obturación endodóntica en el término del conducto radicular sin sobrepasarlo.
Over the course of time, a variety of materials have been used for root fillings, such as asbestos, gypsum, precious metals, bamboo, glass ionomers and epoxy resins; However, several of these materials have been discontinued because they have been considered biologically unacceptable and impractical as they may cause inflammation of the periradicular tissues, resulting in painful sensitivity in the medium or long term after endodontic treatment has been completed. The objective of this research was to analyze the damage produced in the periodontal ligament when bonded with root seal cements. The methodology used was documentary, descriptive, qualitative and exploratory. The cytotoxic agents found in the sealants and the consequences of this irregularity in the periapical tissues should be a reference to strictly avoid the transapical leakage of endodontic cement when filling root canals. He results showed that all sealants used in endodontics cause cytotoxicity in the periradicular tissues to a lesser or greater degree, so it is necessary to apply them correctly to reduce these undesirable effects. It was concluded that those sealers that have antimicrobial agents are the ones that mostly cause damage to the periapical tissues, producing effects such as inflammation, damage to the connective fibrous tissue, bone resorption and tissue necrosis, therefore it is recommended to limit the endodontic obturation to the end of the root canal without exceeding it.
