Question

Quizplus · Accepted Answer

G.V.Black's classification system identifies five classes of decay based on the location of the cavity on the tooth. Mesial decay on tooth #7 would be categorized as Class III, which involves the proximal surface of anterior teeth (i.e., incisors and canines) or the distal surface of posterior teeth (i.e., premolars and molars). Class I refers to pits and fissures of occlusal surfaces of posterior teeth, Class II refers to proximal surfaces of posterior teeth, Class IV refers to proximal surfaces of anterior teeth including the incisal edge, and Class V refers to the gingival third of facial or lingual surfaces of any tooth. Class V may also include the incisal edge or cusp tips.
