In addition to the ICDAS detection codes there may be other elements which are desirable to record in clinical research such as those illustrated in the column headings of the table below relating to other lesion detection aids and information to aid care planning.

In order to use the ICDAS criteria in clinical research the following conditions are essential to enable examiners to assess each of the caries codes accurately: overhead operating light; cleaned teeth and compressed air.


Notes to accompany table
Column 1: Relationship between scores 0-6 in the table and histological depth
Scores  Histological depth
0  No enamel demineralization or a narrow surface zone of opacity (edge phenomenon)
1  Enamel demineralization limited to the outer 50% of the enamel layer
2  Demineralization involving between 50% of the enamel and 1/3 of the dentine
3  Demineralization involving the middle 1/3 of the dentine, clinically microcavitated
4 (3)  Demineralization involving the middle 1/3 of the dentine, clinically shadowed
5 (4)  Demineralization involving the inner 1/3 of dentine± into the pulp, clinically cavitated but the cavitation < ½ the surface
6 (4)  Demineralization involving the inner 1/3 of dentine± into the pulp, clinically cavitated but the cavitation > ½ the surface

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 column 2. +=active lesion;- =arrested lesion
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: Scores for ECM; classification of lesion severity: Only occlusal
  
  0= -0.45-1.0
  1= 1.1-3.0
  2= 3.1-9.0
  3= 9.1-12.0, clinically ±microcavitated
  4= 9.1-12.0 Clinically shadowed
  5= >12 Clinically cavitated but < ½ the surface
  6= > 12 Clinically cavitated but > ½ the surface
  
Column 8: Yet to be established
Column 9: Risk assessment:h=high, m=medium, l=low
Column 10: Yet to be established
Column 11: PTO = Preventive treatment option; OTO = Operative treatment option
Column 12: p = progressing; a = arrested; r = regressing
