Everything about Dental Notation totally explained
Dentists, in writing or speech, use several different
Dental notation systems for associating information to a specific tooth. The three most commons systems are the
FDI World Dental Federation notation,
Universal numbering system (dental), and
Palmer notation method. The FDI system is used worldwide, and the universal is used widely in the
USA.
History
A committee of the
American Dental Association (ADA) recommended the use of the Palmer notation method in 1947. Since this method required the use of symbols, its use was difficult on keyboards. As a result, the association officially supported the universal system in 1968. The
World Health Organization and the
Federation Dentaire Internationale officially uses the two-digit numbering system of the FDI system.
Palmer notation method
FDI World Dental Federation notation, it overwhelming continues to be the preferred method used by dental students and practitioners in the
United Kingdom. It was originally termed the "Zsigmondy system" after the Hungarian dentist
Adolf Zsigmondy who developed the idea in
1861, using a
Zsigmondy cross to record quadrants of tooth positions.. Adult teeth were numbered 1 to 8, and the child primary dentition (also called deciduous, milk or baby teeth) were depicted with a quadrant grid using Roman numerals I, II, III, IV, V to number the teeth from the midline distally. Palmer changed this to A, B, C, D, E.
The Palmer notation consists of a symbol (┘└ ┐┌) designating in which quadrant the tooth is found and a number indicating the position from the midline. Adult teeth are numbered 1 to 8, with deciduous (baby) teeth indicated by a letter A to E. Hence the left and right maxillary central incisor would have the same number, "1", but the right one would have the symbol, "┘", underneath it, while the left one would have, "└".
