Evaluation of mental foramen – A CBCT assessment
The knowledge on the anatomic characteristics and variations of Mental Foramen is very important in surgical procedures involving that area. The mental nerve may be injured during local anesthesia, endodontic treatment and other oral surgical procedures.
Aim of the study: The study performed aimed at assessing position of the MF relative to the apices of the teeth and MF to lingual cortex and to the base of the mandible.
Materials and Methods: The study was conducted using Care stream 9100 select CBCT machine on 50 patients. Measurements were made from the edges of the mental foramen to the lingual cortex, and to the base of the mandible. The inferential statistics were performed using “independent t-test” and the p-value (< 0.05) is calculated using the same. The statistics were performed using SPSS 20software.
Results: In terms of the location of mental foramen, it is most commonly found in the line of long axis of 2nd premolar. In case of measurements of mental foramen from the lingual cortex and lower body of mandible. The lingual edge of MF to lingual cortex was located, on average of 3.3mm in males and 3.8mm in females and the lower edge of the MF was located, 8.4 mm (males) & 7.1 mm (females) above the lower edge of mandible.
Conclusion: The location of the mental foramen greatly influences the surgical planning .Hence there is need and importance of studies involving the anatomical characteristics of the mental foramen, which permit procedures to the performed more safely on the mandible.
