[Diagnostic means using oral and maxillofacial cone beam computed tomography: results].

Every imaging test is justified by clinical facts and optimized to reduce the X-rays dose delivered to patients. If results from orthopantomogram are inadequate, a cross-sectional tomographic technique is indicated. Today, cone beam computed tomography yields images comparable to CT scan or even better. Some dedicated cone beam machines allow the study of small volumes with a very high definition. Dental and maxillofacial imaging as a whole, including endodontic imaging, formerly dreaded by imagers, is now accessible to cross-sectional imaging.
