Where are the mandibular tori located?

1. On the outer surface of the mandible

2. On the lingual side opposite the mandibular canines

3. On the upper jaw

4. On the anterior portion of the mandible

The correct answer is: On the lingual side opposite the mandibular canines

The mandibular tori are bony growths that typically occur on the lingual (inner) side of the mandible, opposite the mandibular canines. This anatomical feature is important in dental practice as it can affect procedures such as impressions and the placement of dentures. The presence of mandibular tori can vary among individuals, but they commonly appear as nodular projections and can sometimes be mistaken for pathology if not recognized. The choice specifying the outer surface of the mandible refers to the buccal side, where anatomical structures differ significantly from the lingual side. The option mentioning the upper jaw inaccurately identifies the location of the tori since they are specific to the lower jaw (mandible) and do not apply to the maxilla (upper jaw). Lastly, while the anterior portion of the mandible is relevant, the tori are specifically located more laterally rather than strictly in the anterior region, making that description less accurate.
