Which notation system uses a quadrant symbol and numbers 1-8 for teeth?

• A. Universal Numbering System
• B. FDI Notation
• C. Tooth Numbering by Arch
• D. Palmer Notation

Answer: (D)

Palmer Notation uses a bracket-like quadrant symbol to indicate which section of the mouth, combined with numbers 1 through 8 to identify the tooth position within that quadrant. The quadrant symbol shows the arch and side (upper right, upper left, lower right, lower left), and the numbers run from the central incisor (1) to the third molar (8) in that quadrant. This is distinct from the Universal System, which numbers teeth 1–32 across the whole mouth, and from FDI Notation, which uses two digits without a quadrant symbol. Palmer is the system that pairs a quadrant marker with 1–8 in each quadrant.
