This article aims to introduce or upgrade health professionals about the applicability of the use of Cone-beam Tomography in clinical and surgical studies of the head of mandible. Due to its location and functionality, the head of mandible has great importance in various specialties and, imaging tests are recommended for therapeutic methods. Regular radiographs show superimposed images of the mandibular region, hampering the morphological assessments. Through more precise images that identify minimal changes, the Cone‑beam Tomography is an imaging method that optimizes the routine clinical performance by improving the diagnostic accuracy, since it makes visible three-dimensional bone structures and corrects overlapping areas.
