Question

The mandibular canal may be seen in the mandibular molar periapical radiographs; it runs from the mandibular foramen to the:

A) Mental foramen
B) Maxillary tuberosity
C) Lingual foramen
D) Mental tubercle

Answer 1

The mandibular canal starts at the mandibular foramen and its endpoint is the mental foramen, which is involved in numbing dental procedures.

Step-by-step explanation:

The mandibular canal, which is visible in mandibular molar periapical radiographs, begins at the mandibular foramen and runs down the length of the mandibular body. It carries the sensory nerve and blood vessels that supply the lower teeth. This pathway is crucial for dental procedures as anesthesia is often injected near the mandibular foramen to numb the lower teeth. The canal's endpoint is the mental foramen, an opening on each side of the anterior-lateral mandible which serves as the exit site for the sensory nerve that provides sensation to the chin.
