[Exploration of destructive lesions of the jaws].

The destructive lesions of the jaws destroying the normal bone structure with involvement of the cortex are mostly diagnosed incidentally during a dental examination. or imaging examination for another pathology. The rest of the time they are suspected in front of an aesthetic deformation of the face, in particular of the cheek or the chin. In order to explore these lesions we use the Panoramic Radiography, Computed Tomography (CT) without and with intravenous injection of contrast medium, Cone Beam Computed Tomography (CBCT) and nuclear Magnetic Resonance Imaging (MRI). This article aims to determine the diagnostic range of destructive lesions of the jaws by CT, especially by CBCT, and to propose a diagnostic algorithm according to the circumstances of discovery of these lesions.
