Question

ICDAS 2 Distinct visual change in enamel when viewed wet: Code 2 A) There is a carious opacity or discoloration that is not consistent with the clinical appearance of sound enamel (Note: the lesion is still visible when dry). The lesion is located in close proximity (in touch or within 1 mm) of the gingival margin. B) Cavitation in opaque or discolored enamel exposing the dentin beneath. C) Sound enamel with no visible changes. D) Lesion consistent with normal enamel appearance.

Answer 1

ICDAS Code 2 refers to a distinct visual change in enamel, indicative of dental caries. It positions the lesion in the enamel, distinguishable from sound enamel and significant as it can lead to more serious conditions if not treated.

Step-by-step explanation:

The ICDAS (International Caries Detection and Assessment System) provides criteria for the classification of dental caries and includes several codes that represent the progression of carious lesions. Code 2 refers to a distinct visual change in enamel when viewed wet, indicating a lesion within the enamel that does not have the appearance of sound enamel and remains visible when dry. This can be caused by acid production from bacterial colonies feeding on sugars and leading to enamel degradation. If a lesion progresses it can extend through the enamel to the underlying dentin, and without treatment, may eventually reach the pulp cavity resulting in more severe complications such as abscesses or periodontitis.
