Definition: Benign bony overgrowths (hyperostosis) on the lingual aspect of the mandible.
Radiographic Features:
- Location:
- Visible on mandibular periapical radiographs
- Sometimes seen on bitewing radiographs
- Most commonly observed on mandibular anterior periapicals
- Edge: Well-defined to well-localized
- Shape: Round to ovoid
- Internal:
- Radiopaque
- Radiopacity similar to surrounding bone
- Number:
- May be single (unilateral)
- More commonly multiple (bilateral)
Key Diagnostic Sign:
- Radiopaque, rounded projections on lingual mandibular surface
Clinical Significance:
- Usually asymptomatic
- Can interfere with denture fitting or placement
- May complicate oral hygiene maintenance
- Rarely require treatment unless causing functional issues
Note: While typically visible on radiographs, clinical examination is crucial for definitive diagnosis. The bilateral nature of mandibular tori is a common characteristic that aids in identification.
