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.
How do you chart supernumerary primary teeth?
Charting Supernumerary Teeth
- When charting permanent teeth, add 50 to the closest standard tooth number. For example, if a supernumerary tooth is adjacent to tooth 12, the tooth number entered would be 62.
- When charting primary teeth, add the letter “S” after the closest standard tooth number.
How do you classify supernumerary teeth?
According to the location of supernumerary teeth, they can be classified as mesiodens [situated at the midline], paramolar [situated vestibularly between the second and third molars, and distomolar [situated distally of the third molar]. They may show vertical, inverted, or transversal orientations (8).
