| In order to use the ICDAS criteria in clinical practice the following conditions are essential to enable examiners to assess each of the caries codes accurately: overhead operating light; cleaned teeth and compressed air. Since caries forms in areas of plaque stagnation it is essential that the teeth are cleaned with at least a toothbrush and floss before conducting an examination using the ICDAS criteria. |
International Caries Assessment and Detection System (ICDAS)
ICDAS shared vision
- ICDAS is a clinical scoring system for use in dental education, clinical practice, research, and epidemiology.
- ICDAS is designed to: lead to better quality information to inform decisions about appropriate diagnosis, prognosis, and clinical management at both the indivdual and public health levels.
- and ICDAS provides a framework to support and enable personalised total caries management for improved long term health outcomes.
The ICDAS International Caries Classification and Management System is under development following a Workshop at Temple in April and an open Symposium in Montpellier in July
Clinical Practice
Explanation to the table
| Column 1: | Terms of increasing severity stages of caries for lay persons |
| Column 2: | Terms for the visual apperance for increasing severity stages of caries for professionals |
| Column 3 | Related scores to coulmn 2 |
| Column 4: | Activity assessment posibilities for the scores in column 3 and thus also columns 2 and 1 |
| Column 5: | Scores for radiographical classification of lesion severity: |
| 0=no radiolucency | |
| 1= radiolucency in outer ½ of the enamel | |
| 2= radiolucency in inner ½ of the enamel± EDJ | |
| 3= radiolucency limited to the outer 1/3 of dentine | |
| 4= radiolucency reaching the middle 1/3 of dentine | |
| 5= radiolucency reaching the inner 1/3 of dentine, clinically cavitated | |
| 6= radiolucency into the pulp, clinically cavitated | |
| Column 6: | Scores for Fibre-optic translumination (FOTI); classification of lesion severity: Proximal and occlusal |
| 0= no shadow or stained area | |
| 1= Lesion stays the same width when transilluminated/Thin grey shadow into enamel when transilluminated | |
| 2= Wide grey shadow into enamel when transilluminated | |
| 3= Wide grey shadow into enamel with no evidence of dentine shadow | |
| 4= Orange/brown or bluish/black shadow < 2mm in width | |
| 5= Shadow as described above and/or transillumination light is blocked > 2mm in width | |
| 6= Large area of frank cavitation with likely pulpal involvement | |
| Column 7: | Risk assessment:h=high, m=medium, l=low |
| Column 8: | PTO = Preventive treatment option; OTO = Operative treatment option |
| Column 9: | p = progressing; a = arrested; r = regressing |
