Manejo endodôntico de canais radiculares em forma de c: revisão de literatura

Abstract

The aim of this study is to discuss the proper management of C - shaped canals through a literature review, explaining morphology, prevalence, classification, diagnosis and treatment of this anatomical variation. The databases used were Pubmed / Medline and COCHRANE. The key words used during they survey were: C-shaped canals, endodontics and filling. A total of 140 articles were found and 31 of which were used in the present study because its fulfilled the inclusion and exclusion criteria. It was concluded that the C-shaped root canals are more frequently found in lower second molars, presenting a dependent population incidence; For classification and diagnosis, imaging tests are essential, especially concomitant computed tomography (CBCT); The techniques for conducting the chemical-mechanical preparation and the obturation stage are hampered by the anatomical complexity inherent to the C-shaped root canal system, but this can be overcome according to the quality of the technique and its good indication; When all stages of treatment are performed with quality, the follow-up results demonstrate a correct clinical prognosis, thus showing that C- shaped root canals although challenging can be treated satisfactorily.
