Anatomical characteristics of the mandibular lingual foramina observed on limited cone-beam CT images.

Objectives: The study aimed to investigate the regional frequency and anatomical properties of mandibular lingual foramina.

Material And Methods: The regional frequency of the lingual foramina was investigated using limited cone-beam computed tomographic images of mandibles obtained from 190 examinations of 181 patients. The mesio-distal position of the lingual foramina was classified into 17 areas of the midline area and each tooth area.

Characteristics of accessory mental foramina observed on limited cone-beam computed tomography images.

In this retrospective study with limited cone-beam computed tomography (limited CBCT), we investigated the anatomic characteristics of the accessory mental foramina and accessory branches of the mandibular canal. The CBCT records of approximately 150 patients were evaluated, and 17 accessory mental foramina were found in 16 patients. The anatomic peculiarities of the mandibular canal that might be relevant to endodontic treatment were observed.
