Metodologias de identificação da anatomia dos canais radiculares dos pré-molares superiores: revisão sistemática.

Abstract

The main objective of this research was to carry out a systematic review of the different methodologies used to understand the root anatomy of maxillary premolars. The electronic databases used to carry out the review were: VHL (Medline, Lilacs, BBO), Cochrane Library and Scopus, restricted to the retroactive period of 10 years, 2010 to 2020. The descriptive terms for search strategy in the databases data, as well as the mesh terms and related entry terms were as follows; (maxillary premolar OR maxillary first premolar OR maxillary second premolar AND root channel morphology OR Root anatomy OR root channel system configuration). The following inclusion criteria were considered: research articles of an epidemiological nature that used several identification methods both in vivo and ex alive. Considered as exclusion criteria: research articles prior to 2010, research carried out on lower premolar teeth and which did not fit the research objectives. The number of roots of the first pre-superior is mostly different from the second pre-superior, since in one one there is a higher percentage of two roots and in the other one root respectively. The number of root canals of the first and second premolars also presented differently, however following their root anatomy, greater occurrence of two channels for the first premolar and lesser occurrence for the second. In the Vertucci classification, the first premolar showed a higher occurrence for typeIV while the second for I. The most used diagnostic method was Cone Beam Computed Tomography
