caries or restorations that occur in proximal surfaces of posterior teeth; the occlusal surfaces are usually involved

caries or restorations that occur in proximal surfaces of incisors and canines; the incisal angle is not involved

caries or restorations that occur in the proximal surfaces of incisors and canines including the incisal edge

caries or restorations that occur in the gingival third of facial or lingual surfaces of any tooth

caries or restorations that involve the incisal edge of anterior teeth and the cusp tips of posterior teeth
