Caries Associated with Restorations and Sealants Codes
Sound tooth surface with restoration or sealant: Code 0

A sound tooth surface adjacent to a restoration/sealant margin. There should be no evidence of caries (either no or questionable change in enamel translucency after prolonged air drying for 5 seconds). Surfaces with marginal defects less than 0.5mm in width (i.e. will not admit the ball end of the CPI Probe), developmental defects such as enamel hypoplasias; fluorosis; tooth wear (attrition, abrasion and erosion), and extrinsic or intrinsic stains will be recorded as sound. Stained margins consistent with non-carious habits (e.g. frequent tea drinking) and which do not exhibit signs consistent with demineralization should be scored as sound

First visual change in enamel: Code 1

When seen wet there is no evidence of any change in color attributable to carious activity, but after prolonged air drying (for approximately 5 seconds) an opacity or discoloration consistent with demineralisation is visible that is not consistent with the clinical appearance of sound enamel.

Distinct visual change in enamel/dentin adjacent to a restoration/sealant margin: Code 2

 If the restoration margin is placed on enamel the tooth must be viewed wet. When wet there is an opacity consistent with demineralisation or discoloration that is not consistent with the clinical appearance of sound enamel (Note: the lesion is still visible when dry).

 If the restoration margin is placed on dentin: Code 2 applies to discoloration that is not consistent with the clinical appearance of sound dentin or cementum.

 

Carious defects of <0.5 mm with the signs of code 2: Code 3

Cavitation at the margin of the restoration/sealant less than 0.5mm, in addition to either an opacity or discoloration consistent with demineralisation that is not consistent with the linical appearance of sound enamel or with a shadow of discolored dentin.

Marginal caries in enamel/dentin /cementum adjacent to restoration/sealant with underlying dark shadow from dentin: Code 4

The tooth surface may have characteristics of code 2 and has a shadow of discolored dentin which is visible through an apparently intact enamel surface or with localized breakdown in enamel but no visible dentin. This appearance is often seen more easily when the tooth is wet and is a darkening and intrinsic shadow which may be grey, blue, orange, or brown in color. Note: view tooth wet and then dry. This lesion should be distinguished from amalgam shadows.

Probe

 

Distinct cavity adjacent to restoration/sealant: Code 5

Distinct cavity adjacent to restoration/sealant with visible dentin in the interfacial space with signs of caries as described in code 4, in addition to a gap > 0.5mm in width. OR In those instances where margins are not visible, there is evidence of discontinuity at the margin of the restoration/sealant and tooth substance of the dentin as detected by 0.5mm ball-ended probe run along the restoration/sealant margin.

Probe

Extensive distinct cavity with visible dentin: Code 6

Obvious loss of tooth structure, the extensive cavity may be deep or wide and dentin is clearly visible on both the walls and at the base.
