Torus Mandibularis
Pronunciation: TOR-us man-DIB-yoo-LAH-ris
A benign bony exostosis occurring on the lingual aspect of the mandible, typically bilateral and located in the premolar region, representing a normal anatomical variant.
Full Definition
Torus mandibularis presents as smooth, hard nodular prominences on the lingual surface of the mandible, most commonly in the premolar area above the mylohyoid line. The condition is bilateral in the majority of cases and is more prevalent in certain ethnic populations, suggesting a hereditary component. Like torus palatinus, it is covered by thin mucosa susceptible to ulceration from trauma and may require surgical reduction for denture accommodation. Editors should note the Latin plural form is 'tori mandibulares'. The term is distinct from torus palatinus despite both being classified as exostoses.
Usage
Usage note: Plural: 'tori mandibulares'. Distinguish from torus palatinus by anatomical location. Both are exostoses but are epidemiologically and clinically distinct entities.
