Three incompatible systems for naming the same tooth.
Also known as: FDI notation, Palmer notation, Universal numbering system
Three tooth numbering systems are in use: the FDI two-digit system internationally, the universal numbering system in the United States, and Palmer notation in British orthodontics. The same tooth is 16, 3 and an upper right 6 in the three systems, so a record without its system is unusable.
Identifies an individual tooth, in one of three incompatible systems in current use.

Contexts: Medicine
Uses a quadrant-plus-position two-digit code in the international FDI system, which is why FDI numbers run from eleven to forty-eight with no teeth numbered one to ten.
