Lingual foramen is described as?

• A. A canal on buccal surface
• B. A foramen within the genial tubercle; appears radiolucent.
• C. A tubercle near mental foramen
• D. A nutrient canal in maxilla

Answer: (B)

Lingual foramen is a small opening on the lingual (inner) surface of the mandible, located in the area of the genial tubercles (mental spines). It transmits vessels and nerves toward the tongue, so on dental radiographs it shows up as a tiny radiolucent hole within that region. This matches the description of a foramen within the genial tubercle and appearing radiolucent. It isn’t on the buccal surface, it isn’t a tubercle near the mental foramen, and it isn’t a nutrient canal in the maxilla, which helps distinguish it from the other options.
