Análise da influência do alargamento foraminal no tratamento endodôntico: uma revisão de literatura.

Abstract

In endodontic therapy, the size of the apical enlargement appears as a controversial issue among clinicians and researchers. Currently, the focus is in the search for suitable size of the apical foramen enlargement and limit shutter according to the complexity of the apical third of a tooth. This study analyzed through a literature review the influence of foraminal expansion in endodontic treatment. We conducted a search for scientific articles to the theme addressed clarification published between 1968-2016 and accessed in Scielo databases, LILACS, PubMed and UNICAMP Digital Library in 2016. theses were used and national and international scientific papers available full text relating to endodontic instrument within the foraminal patency, diameter enlargement of the apical foramen and its extension, postoperative pain, cleaning apical region of the periapical debris extrusion and foraminal transport after techniques involving enlargement foraminal. According to the review carried out, the results were favorable to the use of tactical operative enlargement of the apical foramen. Regarding the modeling of the root apex size # 40 presents satisfactory results in relation to enlargement and the sealing has better quality when the instrumentation is conducted in the foramen limit. Postoperative pain wasn't observed in vital teeth, but molars with pulp necrosis occurred slight increase in pain. The expansion showed no interference effective in treatment. It can be concluded that the use of foraminal enlargement presents favorable results for endodontic treatment.
