|May 1, 1976
Summary
Accurate identification of the mental foramen in periapical radiographs is crucial for dental procedures. Most mental foramina are located between the premolars horizontally and above the premolar roots vertically.
Area of Science:
- Dentistry
- Oral and Maxillofacial Radiology
- Anatomy
Background:
- The mental foramen is a critical anatomical landmark in the mandible.
- Accurate localization is essential for safe and effective dental procedures, particularly those involving the lower jaw.
Purpose of the Study:
- To determine the precise location of the mental foramen in both horizontal and vertical planes using periapical radiographs.
- To provide anatomical data for improved surgical planning and reduced risk of neurovascular complications.
Main Methods:
- Analysis of 1000 full-mouth intraoral periapical radiographs.
- Registration of the mental foramen's position in the horizontal and vertical planes relative to adjacent teeth.
Main Results:
- Horizontally, 70% of mental foramina were located between the two premolars.
- Additionally, 22% were found in the apical region of the premolars.
- Vertically, the majority of mental foramina were positioned superior to the premolar apices.
Conclusions:
- The mental foramen's typical location is between the premolars and superior to their apices.
- Radiographic assessment is vital for precise localization, aiding clinicians in avoiding damage to the mental nerve and vessels.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
