BACKGROUND: The mental foramen (MF) is an essential anatomical structure for mental block anesthesia in dental practice and maxillofacial surgery. The literature also reports the importance of knowing the morphometric characteristics of the mental foramen because it can be damaged during maxillofacial surgery and dental implantology. The aim of our study was to determine anthropometric characteristics of mental foramen in a selected Cameroonian population.
METHODS: A total of 192 CT-scan of patients were included in our research. The data was collected from cerebral CT-Scan in three-dimensional reconstruction of patients. The transverse and vertical diameters of the mental foramen and its distance to the midline and lower border of the mandible were measured and the shape determined.
RESULTS: One hundred ninety-two CT-scan of patients were analyzed. The mean transverse diameter of the mental foramen (MF) on the left side was 2.5±0.9 mm while on right it was 2.6±0.6 mm. The mean vertical diameter of the right foramen was and 2.9±0.8 mm and it was 2.8±0.7 mm for the left side. The left foramen was located at 31.5% on the line above the 2nd premolar and between the 2nd premolar and 1st molar at 28.3%. The left foramen was oval in 165 subjects (79%) while the right was oval for 90.2% of patients.
CONCLUSIONS: Knowledge of the precise anatomical location of MF is important in surgical procedures and reduce the relative risks during clinical procedures. This study showed many differences in the location of the mental foramen with caucasians measurments done.
