Study Notes
- Teeth numbering systems aim to identify each tooth in a clear and standardized way.
- The graphic representation of the dental arches assumes the examiner is facing the patient.
- The horizontal line between the upper and lower arches is a universally adopted notation element.
- The vertical line, or median line, divides arches into left and right sides.
- When determining left or right tooth position, the patient's left or right side is considered.
- Dental nomenclature assigns a name to each tooth, including terms like permanent or temporary, maxillary or mandibular, superior or inferior, right or left.
- Example: right permanent maxillary canine
- The following are main teeth numbering systems:
- Anglo-Saxon (Palmer) system
- Arithmetic system
- French system
- FDI system
- American system
Arithmetic System
-
- is used for right or left upper arch teeth notation
-
- used for right or left lower arch teeth notation
- Some variations of it use roman numerals
Angular System
- The angular system is an outdated numbering method.
- This system identifies teeth using angles formed by intersecting horizontal and vertical lines relative to the dental arches.
- Permanent teeth are numbered with Arabic numerals, while temporary teeth use lowercase letters.
French System
- This system uses letters rather than numbers
- S, D are used for designation of hemiarcades (superior, dextra)
- s, d designate the inferior hemiarcade (sinistra, dextra)
FDI System (Federation Dentaire Internationale)
- Universally recognized system that was invented by Pirquet in 1924
- Modified by the FDI in 1971 in Bucharest
- This system uses two digits to identify each tooth
- It is easy to understand.
- Reduces possibility of mistaking teeth.
- Data can be input into computerized programs
- The first digit indicates the quadrant (1 to 4 for permanent teeth), and the second digit indicates the tooth position in that quadrant.
- Right superior permanent hemiarcade: 1
- Left superior permanent hemiarcade: 2
- Right inferior permanent hemiarcade: 4
- Left inferior permanent hemiarcade: 3
- A quadrant number from 5 to 8 indicate temporary teeth
- Right superior temporary hemiarcade: 5
- Only uses Arabic digits.
American System
- It is a numbering system that uses sequential numbers or letters to designate each tooth in the mouth.
- Permanent teeth are uniquely numbered from 1 to 32.
- Temporary teeth are labeled with letters A through T.
- begins with the upper right third molar (wisdom tooth) as 1 and ends with the lower right third molar as 32
- In permanent teeth, the numbering begins with the upper right molar and proceeds continuously.
