Black classification includes which of the following?

• A. 2 classes
• B. 3 classes
• C. 4 classes
• D. 5 classes

Answer: (D)

G. V. Black's caries classification groups lesions by where they occur on teeth, totaling five classes. Class I refers to caries in pits and fissures on occlusal surfaces of posterior teeth and in buccal or lingual pits. Class II involves proximal surfaces of posterior teeth. Class III covers proximal surfaces of anterior teeth that do not involve the incisal edge. Class IV is proximal surfaces of anterior teeth that do involve the incisal edge. Class V includes lesions on the cervical third of facial or lingual surfaces. This five-category system is the traditional framework used to document the location of caries, guiding assessment and treatment planning. While some modern discussions add a sixth category for cusp-tip or incisal-edge wear, the classic and widely taught version comprises five classes.
