Dental Formulary
A symbolic notation system representing the number and types of teeth in each quadrant of the mouth for a specific species or developmental stage.
Full Definition
A dental formulary (or dental formula) uses a standardized numeric shorthand to describe the dentition of an individual or species, listing the number of incisors, canines, premolars, and molars per quadrant. In humans, the permanent dental formula is I 2/2, C 1/1, P 2/2, M 3/3, giving a total of 32 teeth. The deciduous formula is I 2/2, C 1/1, M 2/2, totalling 20 teeth. Editors must distinguish 'dental formula' as a notational convention from 'dental formulary' as used in insurance contexts (a list of covered procedures or drug approvals), noting that these are distinct uses of near-identical terms.
Usage
Usage note: In insurance and healthcare administration, 'dental formulary' means a list of approved dental procedures or materials — an entirely different meaning from the anatomical notational sense. Flag ambiguous usage.
