Evaluation of retromolar canals on cone beam computerized tomography scans and digital panoramic radiographs.

Purpose: The purpose of this study was to carry out morphologic and topographic analyses of retromolar canals on cone beam computerized tomography (CBCT) scans, comparing findings to others obtained from the corresponding digital panoramic radiographs.

Methods: Sixty-one CBCT scans were analysed digitally, as well as their corresponding digital panoramic radiographs. The prevalence and distribution of these canals, foramen diameters, and intraosseous communications were also evaluated.

Tomographic Evaluation of Accessory Canals Penetrating at the Inner Side of the Anterior Region of Mandibles.

Background: The anterior region of the mandible is generally considered to be a safe region to invasive procedures; however, on its internal face, uncountable penetrating canals may be encountered.

Objective: To perform morphometrical and topographical analysis of endosseous canals located at the inner side of the mandibular anterior region, using cone-beam computed tomography.

Methods: Forty-six examinations were digitally analyzed.
