Determination of the position and morphology of the mental foramen using cone beam computed tomography
Summary:
Introduction. The mental foramen (MF) is a bilateral opening localized on the anterior surface of the mandible. A precise location, as well as well-defined shape, and prevalence accessory MF is crucial for different clinical dental procedures. The aim of this study was to determine location and shape of the MF and the presence of accessory MF (AMF) and anterior loop in Greek patients using the cone-beam computed tomography (CBCT) study. Material and Methods. 67 patients (33 males and 34 females) in the age group between 16 and 71 years were included in our retrospective study and were examined at the Dental School of Athens using cone‑beam computed tomography (CBCT). The right and the left MF locations and the presence of the anterior loop were determined from panoramic images. On the cross‑sectional CBCT images, the distance of the MF upper limit from the alveolar crest edge and the distance of the MF lower limit from the lower edge of the mandible were measured. The 3D reconstruction of CBCT was used to detect the AMFs. Results. The study revealed that the most common position of MF was between 1st and 2nd premolar. Anterior loop was observed in 20, 9% of the cases. Conclusions. The application of the CBCT study enabled a precise determination of the position and morphology of the mental foramen in relation to the neighboring anatomical structures on a representative group of the Greek patients.
