This study identified a rare mandibular incisive foramen (MIF) using Cone Beam CT, distinct from the mental foramen (MF). This finding highlights potential risks to nerves during dental procedures.
Area of Science:
- Anatomy
- Radiology
- Dentistry
Background:
- The mandibular incisive foramen (MIF) is an anatomical landmark on the mandible, with limited existing evidence.
- Its precise location and differentiation from the mental foramen (MF) are crucial for dental procedures.
Purpose of the Study:
- To document and analyze a case of a mandibular incisive foramen (MIF) using Cone Beam Computed Tomography (CBCT).
- To differentiate the MIF from the mental foramen (MF) and assess associated anatomical risks.
Main Methods:
- A retrospective Cone Beam CT (CBCT) analysis of a 56-year-old male patient's mandibular anatomy.
- Detailed examination of foramina in the left hemimandible's second premolar region.
Main Results:
- Two adjacent foramina were identified: a distal foramen opening medially and a medial foramen oriented distally.
- CBCT confirmed the distal foramen as the opening of the mandibular canal and the medial foramen as the entrance to the mandibular incisive canal (MIF).
Conclusions:
- CBCT is effective in distinguishing the mandibular incisive foramen (MIF) from the mental foramen (MF).
- The presence of adjacent foramina poses risks to the mental nerve, inferior alveolar nerve (IAN), and mandibular incisive nerve.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
