Questions & Answers

Q: Why was there a need for a new dental caries classification system?

The previous classification system had limitations, such as only identifying cavitated lesions and failing to identify early stages of tooth decay. The new system aims to overcome these limitations and improve early detection and treatment.

Q: What are non-cavitated lesions?

Non-cavitated lesions refer to early stages of tooth decay where there is an imbalance in the demineralization and remineralization processes. These lesions can be identified by changes in color, glossiness, and surface texture of the tooth.

Q: How are cavitated lesions different from non-cavitated lesions?

Cavitated lesions occur when the surface integrity of the tooth is compromised, leading to irreversible loss of enamel. These lesions indicate progressive dental caries and may have either micro or macro cavitations.

Q: What are the main categories of the American Dental Association's caries classification system?

The new classification system includes four categories: sound (no detectable caries), initial (mild demineralization limited to enamel or shallow demineralization of cementum and dentin), moderate (visible enamel breakdown and moderate demineralization), and advanced (fully cavitated lesion with severe demineralization and exposed dentin).
