Palatal
Pronunciation: PAL-uh-tul
Relating to or directed toward the palate; used to describe the inner surface of upper teeth facing the roof of the mouth.
Full Definition
In dental contexts, 'palatal' is the preferred directional term for upper (maxillary) tooth surfaces and tissues that face the hard or soft palate. It is anatomically more precise than 'lingual' when describing the maxillary arch, since the equivalent structure in the mandible faces the tongue rather than a palate. Editors working on clinical notes, prosthodontic prescriptions, and orthodontic reports should ensure that 'palatal' and 'lingual' are not used interchangeably without clinical justification.
Usage
Usage note: Reserve 'palatal' for maxillary arch descriptions. Using 'palatal' in a mandibular context is anatomically incorrect and should be queried.
