Torus Palatinus
Pronunciation: TOR-us pal-ah-TY-nus
A benign, bony exostosis arising along the midline of the hard palate, representing a common anatomical variation with no malignant potential.
Full Definition
Torus palatinus is the most prevalent intraoral exostosis, presenting as a nodular or lobulated bony protuberance at the midpalatine raphé. It is thought to have a multifactorial aetiology involving genetic predisposition and functional jaw forces. Clinically it is covered by thin, easily traumatised mucosa and is asymptomatic unless ulcerated by trauma or requiring surgical removal prior to denture construction. Editorial convention mandates the use of the Latin plural 'tori palatini' when describing multiple lesions or the category as a whole. It must not be confused with torus mandibularis (lingual mandibular exostosis) or palatal tonsil tissue.
Usage
Usage note: Use the Latin plural 'tori palatini' in formal texts. Distinguish from torus mandibularis. Overline or italics are not required for these Latin terms in modern oral medicine publishing.
