Sarjeev's supernumerary tooth notation system: A universally compatible add-on to the Two-Digit system.

ABSTRACT

Aim: To give notation for quadrants, tooth position, and the type of supernumerary teeth for both permanent and deciduous dentition. Tooth numbering provides dentists with an essential shortcut in clinical record keeping. Materials and Methods: Three systems are favored worldwide the Zsigmondy/Palmer system, the Universal system, and the Federation Dentaire Internationale (FDI) Two-Digit system. Histories of all tooth-numbering methods were traced and the strengths and deficiencies of each system were reviewed. The FDI Two-Digit system is widely used throughout the world, except USA, and is the only method that makes the visual sense, cognitive sense, and computer sense. Conclusion: On review it was noticed that all tooth notation systems in vogue have a drawback as they do not provide any information or notations for supernumerary teeth such as paramolar, distomolar, mesiodens, and fused teeth.
