Surface of enamel is whitish/yellowish opaque with loss of luster; feels rough when the tip of the probe is moved gently across the surface.

Lesion is in a plaque stagnation area, i.e.: pits and fissures, near the gingival and approximal surface below the contact point.

Surface of enamel is whitish, brownish or black. Enamel may beshiny and feels hard and smooth when the tip of the probe is moved gently across the surface.

For smooth surfaces, the caries lesion is typically located at some distance from the gingival margin.
