Influência da Smear Layer no tratamento endodôntico

Abstract

The endodontic treatment is divided into stages, one of which is the instrumentation of the root canals, regardless of the technique used, this instrumentation produces a layer of debris that is composed of organic and inorganic materials, so that, this layer of debris is adhered to the canal wall. Thus, this study aims, through a literature review, to demonstrate the best conduct to be taken on the need or not to remove this layer of debris, known as Smear Layer, to achieve success in the treatment and a better prognosis for the patient. This research was carried out with existing studies in the databases of Scielo, PubMed and Google Scholar. It was possible to conclude that the removal of the layer Smear Layer is necessary, this is due to the fact that, when present, this layer can obstruct the dentinal canals, and thus end up hindering or even preventing the antimicrobial action of intracanal medications and irrigation solutions, in addition, its removal also provides a better filling of the canal at the time of obstruction, avoiding possible recontamination.
