Resistencia a la fractura de dientes tratados endod?nticamente, obturados con tres tipos de cementos selladores (biocer?micos, resinosos, hidr?xido de calcio). Revisi?n literaria

Abstract

[Espa?ol] Durante el tratamiento endod?ntico existen diversos factores que afectan a la resistencia de la estructura dental. Por lo tanto, es necesaria la incorporaci?n de un cemento sellador dentro del conducto con propiedades capaces de reforzar y fortalecer la estructura dentaria debilitada, adem?s de sellar los conductos radiculares herm?ticamente obteniendo as? un sellado tridimensional. El objetivo de esta revisi?n de la literatura es determinar cu?l es el tipo de cemento sellador endod?ntico (biocer?micos, a base de resina ep?xica y a base de hidr?xido de calcio) que proporciona mayor resistencia a la fractura en dientes tratados endod?nticamente. Fueron incluidos art?culos de la base de datos de diferentes repositorios como Pubmed, Google acad?mico, JOE entre otros. Se concluy? que los cementos selladores biocer?micos y resinosos presentan mayor cantidad de propiedades favorables a la resistencia de la estructura radicular sobre los cementos a base de hidr?xido de calcio.

[English] During endodontic treatment there are several factors that affect the resistance of the dental structure. Therefore, it is necessary to incorporate sealing cement inside the canal with properties capable of reinforcing and strengthening the weakened dental structure, in addition to hermetically sealing the root canals, thus obtaining a three-dimensional seal. The objective of this literature review was to determine which type of endodontic sealing cement (bioceramic, epoxy resin-based, and calcium hydroxide-based) provides greater fracture resistance in endodontically treated teeth. Articles from the database of different repositories such as Pubmed, Google academic, JOE among others were included. It was concluded that bioceramic and resinous sealing cements have greater properties favorable to the resistance of the root structure over calcium hydroxide-based cements.
