Table 1 Diagnostic criteria for ICDAS II and CAST indices
ICDAS II caries detection system | |
|---|---|
Code | Description |
0 | Sound |
1 | Enamel opacity |
2 | District visual enamel cavity |
3 | Localised enamel breakdown |
4 | Underlying dark shadow from dentin |
5 | Dentine distinct cavity |
6 | Dentine extensive cavity |
Code | Description | |
|---|---|---|
CAST diagnostic criteria | ||
0 | Sound | No visible evidence of a distinct carious lesion is present |
1 | Sealants | Pits and/or fissures are at least partially covered with a sealant material |
2 | Restoration | A cavity is restored with an (in)direct restorative material |
3 | Enamel | Distinct visual change in enamel only; a clear caries-related discoloration is visible, with or without localised enamel breakdown |
4 | Dentin | Internal caries-related discoloration in dentine; the discoloured dentine is visible through the enamel, which may or may not exhibit a visible localised breakdown |
5 | Dentin | Distinct cavitation into the dentine; the pulp chamber is intact |
6 | Pulp | Involvement of the pulp chamber; distinct cavitation reaching the pulp chamber, or only root fragments are present |
7 | Abscess/fistula | A pus-containing swelling or a pus-releasing sinus tract related to a tooth with pulpal involvement |
8 | lost | The tooth has been removed because of dental caries |
DMFT index | WHO criteria |
|---|---|
Code | Description |
Sound | If there is no evidence of treated or untreated clinical caries, a crown is categorized as sound tooth |
D | Decayed: carious lesion is clinically visible and obvious/filled tooth with recurrent decay/remaining roots/broken fillings/temporary fillings |
M | Missing: missing teeth due to caries/other cases should be excluded (un erupted teeth. congenital missing, orthodontic extractions etc.) |
Ft | Filled teeth: Permanent Filled teeth due to caries/a tooth has multiple restorations, it is counted as one tooth (F) |
When a tooth has a restoration on one surface and caries on the other, it is considered decayed D | |
No tooth can be counted more than once in the D, M, F, or sound categories |
