Dental professionals, in writing or speech, use several different dental notation systems for associating information with a specific tooth. The three most common systems are the ISO System, Universal Numbering System, and Palmer notation method. The ISO system is used worldwide, and the Universal is used widely in the USA. The ISO System can be easily adapted to computerized charting.
