Description

This anatomical illustration represents Class IV of Black’s Classification of tooth decay, which involves carious lesions affecting the proximal surfaces of anterior teeth, including the incisal edge. In this image, the upper central incisor on the viewer’s right side shows distinct structural damage extending from the interproximal area toward the incisal angle, characteristic of a Class IV lesion. This visual serves as a precise educational tool for understanding advanced anterior decay and planning appropriate treatment strategies.
