Special considerations

Non-vital teeth should be scored in the same manner as vital teeth.
Banded or bracketed teeth. All visible surfaces should be examined as well as possible and scored in the usual manner. When a surface is completely covered by a band or bracket and there is no evidence of caries the tooth status code is “0”.
In the case of supernumerary teeth, the examiner should decide which tooth is the legitimate occupant of the space. Only that tooth should be scored.
When both a primary and permanent tooth occupy the same space, only the permanent tooth is coded.
All surfaces restored with full coverage should be coded as crowned. If a tooth has been restored with anything less than full coverage, the surfaces involved in the restoration will be scored separately.
If a surface has been restored with a partial covering, the other surfaces must be registered separately. And the covered surface must be coded as an excluded surface 96
When more than one lesion is present on the same surface, the most severe must be recorded
All retained root surfaces must be coded as 06
All retained root surfaces must be coded as 06
