Confirmation of the mandibular canal is clinically important to avoid local injury to the nerve during surgical and endodontic rocedures. Especially, it is crucial to identify the anatomic location of the mental foramen. The mental nerve is a somatic afferent sensory nerve of the mandibular nerve that emerges from the mental foramen and which presents as a single circular, or elliptical, bilateral radiolucent area in the premolar region. The evaluations of accessory foramina that relate to the mandibular canal are clinically important in endodontic treatments and surgical procedures such as dental implant insertion, implant-related bone grafting, genioplasty and mandibular anterior segmented osteotomy. The accessory mental nerve is a relevant anatomic structure in dental practice with particular importance for local anesthes. The mental foramen (MF) is a small foramen located in the anterolateral region of the mandible through which the mental nerve and vessels emerge. The knowledge on the anatomic characteristics and variations of MF is very important in surgical procedures involving that areaia and surgical procedures involving this region, such as genioplasty, surgical rehabilitation after mandibular trauma, bone harvesting from the chin, root resection of mandibular premolars, and particularly the placement of dental implants. Two-dimensional radiographs are the most frequent imaging method in the dental field, but intraoral and rotational panoramic radiograph (PAN) images often fail to depict anatomic variations in the MF area. Presurgical tridimensional assessment using computed tomography (CT) could be a more useful tool for determining the presence of AMF. In particular, cone beam computed tomography (CBCT) provides sufficient resolution to allow accurate evaluation of osseous landmarks in the maxillofacial region and presurgical detection of AMF. Thus in this study the Panoramic radiography and cone beam CT will compare to identify of of mental foramen.
