【 摘 要 】

Introduction: Understanding the anatomical variations in the position of mental foramen are significant for different dental procedures. This study identified the position of the mental foramen among a sample of Nepalese population visiting a dental college in Kathmandu. Methods: Total 417 panoramic radiographs (orthopantomograms) were selected from a total of 567 radiographs. The mental foramen location was determined by drawing imaginary line parallel with the long axis of the lower premolars . The mental foramen location was then classified into six classes. Results: In the study population, the mental foramina were located mostly between the lower premolars 163 (39.1%), followed by in line with second premolar 148 (35.5%) of the mental foramen was located under the second premolar apex. Conclusions: The study shows that the anaesthetic solution should be injected between the lower premolars or below the lower 2nd premolar in the Nepalese population for successful and secure mental nerve blocking.
