Orientações de avaliação de imagens radiográficas e tomográficas no planejamento cirúrgico de exodontia dos terceiros molares inferiores

Abstract

The aim of this study was to make a review article of the Classifications of Positions of Mandibular Third Molars in Panoramic Radiographs (PRs) and Cone-Beam Computed Tomography (CBCTs), and produce a practical manual for image evaluation of radiographic and tomographic scans for undergraduate students and dental surgeons. The manual presented the classifications of Pell & Gregory (1933), Winter (1926), radiographic signs of proximity to the mandibular canal in PRs, positions of the mandibular canal in relation to the roots of the mandibular third molars and positions of the mandibular third molars based on the bucco-lingual relationship of the alveolar bone in CBCTs. The material developed for the present study important, since it facilitates and simplifies the way of analyzing panoramic radiographs, and especially the CBCTs, which are three-dimensional exams combined with diagnosis and surgical planning.
