If carious lesion extends below the cemento-enamel junction onto the root surface (gingival third), which G.V. Black class would typically describe this (if defined)?
Show answer and explanation
Correct answer: Not covered by classical G.V. Black classification
Classical G.V. Black classification describes lesions on the anatomical crown (Classes I–VI). Root-surface caries falls outside these classes, as they were not defined in the original scheme.
