Oral tori (singular torus) are benign bony outgrowths from the maxilla and mandible:
- maxillary tori a.k.a. torus palatinus
- mandibular tori a.k.a. torus mandibularis
Oral tori are subcategorised according to their shape 1:
- flat
- spindle
- nodular
- lobular
Although not usually called tori, further benign exostoses arising from the maxilla, with identical histology to oral tori, exist 3:
The diagnosis of any of these benign exostoses is often incidental, usually during "routine" dental examination, as they tend to be asymptomatic.
