What number of classes does Black's classification include?

Explanation:
Black's classification for dental caries is a six-class system, designed to describe caries location on different tooth surfaces. The six classes are pits and fissures (occlusal surfaces and fissures of posterior teeth, including buccal/lingual pits); proximal surfaces of posterior teeth; proximal surfaces of anterior teeth; proximal surfaces of anterior teeth that involve the incisal edge; cervical third of facial or lingual surfaces; and cusp tips or incisal edges. Therefore, the number of classes is six, so five would be incorrect in the standard scheme.
