(1) Partial recording method, namely: Zsigmondy/Palmer notation, referred to as Z/P recording method.
First, it was adopted by the Hungarian dentist Dr. Adolf Zsigmondy (18 16- 1880) in 186 1 year. Later, American dentist Dr. Coriden Palmer revised the records of deciduous teeth. This method is intuitive, popular and widely used, and it is also the most used in China.
Draw a "ten" according to the patient's dentition, and the teeth are divided into four quadrants on average.
1, permanent teeth-represented by Arabic numerals 1-8: 1. Central incisor; 2. lateral incisors; 3. fangs; 4. First premolar; 5. Second premolar; 6. First molar; 7. Second molar; 8. Third molar.
2. The deciduous teeth-Zsigmondy recording method. Represented by Roman numerals I-V: I. Central incisor; Two. Primary incisors; ⅲ. deciduous teeth; Ⅳ. First deciduous molar; ⅴ. Second deciduous molar.
Palmer recording method, with capital letters A-E instead: a. Cutting teeth in milk; B. deciduous incisors; C. deciduous teeth; D. the first deciduous molar; E. second deciduous molar.
(2) The internationally used FDI (International Dental Federation) notation, also called ISO-3950 notation.
Each tooth is represented by two Arabic numerals, and the 1 digit represents the quadrant where the tooth is located. The patient's upper right, upper left, lower left and lower right (clockwise) are quadrants 1, 2, 3 and 4 of permanent teeth and quadrants 5, 6, 7 and 8 of deciduous teeth respectively.
The second digit indicates the position of teeth: 1-8 for permanent teeth and 1-5 for deciduous teeth. For example, 25 represents the upper left second premolar and 53 represents the upper right deciduous tooth.
(3) ADA (American Dental Association) recording method-general recording method.
Each tooth is numbered in the order of right maxillary-left maxillary-left mandibular-right mandibular. Permanent teeth are represented by Arabic numerals 1-32, and deciduous teeth are represented by letters A-T. This recording method is widely used in the United States.
Comparison of different dental position recording methods
Location recording method: intuitive and vivid, the most widely used, suitable for handwriting, but not conducive to computer input and statistical analysis.
FDI method: it is convenient for input and statistical analysis, but its disadvantage is that it is not intuitive enough, and too many outpatients are prone to make mistakes.
ADA method: concise but not intuitive. Now all kinds of friendly electronic medical record software have solved this problem well.
