Okla. Admin. Code § 317:30-5-703

Current through Vol. 42, No. 4, November 1, 2024

Section 317:30-5-703 - Tooth numbering system

(a) For adult teeth, the universal tooth numbering system (1 through 32) is used. For primary teeth, tooth letters A through T are used.

(b) No other tooth letter or number system is accepted. All procedures performed on a specific tooth require the appropriate tooth number.

(c) Supernumerary teeth are identified as follows:

(1)Permanent dentition. Supernumerary teeth are identified by the numbers 51 through 82, beginning with the area of the upper right third molar, following around the upper arch and continuing on the lower arch to the area of the lower right third molar. For example, supernumerary number 51 is adjacent to the upper right molar number 1, and supernumerary number 82 is adjacent to the lower right third molar number 32.

(2)Primary dentition. Supernumerary teeth are identified by the placement of the letter "S" following the letter identifying the adjacent primary tooth. For example, supernumerary "AS" is adjacent to "A" and supernumerary "TS" is adjacent to "T".
