-->1 It was originally termed the Zsigmondy system after the Austrian dentist Adolf Zsigmondy who developed the idea in 1861 , using a '''Zsigmondy cross''' to record quadrants of tooth positions.2. 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. Palmer changed this to A, B, C, D, E. This makes it less confusing and less prone to errors in interpretation. 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, "└". TABLE OF CODES Orientation of the chart is traditionally "dentist's view", i.e. patient's right corresponds to notation chart left. The designations "left" and "right" on the chart, however, nonetheless correspond to the patient's left and right, respectively. With the move from written dental notes to electronic records, some difficulty in reproducing the symbols has been encountered.3 On a standard keyboard 'slash' and 'backslash' may be used as a crude approximation to the symbols with numbers placed before or afterwards; hence 3/ is '''3┘''' and '''/5''' is '''┌5''' One advantage of Palmer notation is that it can produce a very graphical image, akin to a 'map' of the dentition; Tooth Transposition s or Edentulous Space s can easily be depicted if desired. It would also be feasible to introduce additional alphabetic characters or other symbols, for example to denote Supernumerary teeth or Bridge Pontics , to which a purely numerical method such as the FDI system does not lend itself easily.4 SEE ALSO REFERENCES FOOTNOTES |
