Description

This vivid cross-sectional image illustrates stage D3 of dental caries progression, as defined by the radiological classification system. At this advanced stage, the carious lesion has penetrated beyond the enamel and dentin, reaching the pulp chamber. The visual clearly depicts extensive demineralization and decay invading the inner layers of the tooth, with the darkened region representing the infected area and the red pulp chamber indicating potential inflammation or pulp involvement. The image effectively highlights the critical anatomical changes occurring in stage D3, where bacterial infiltration compromises the tooth’s vascular and nerve supply.
