In Black's classification, which class includes caries on the proximal surface of an anterior tooth?

Black's classification system is designed to categorize the location of dental caries and the types of restorative cavities. In this classification, Class III is specifically designated for carious lesions that occur on the proximal surfaces of anterior teeth, which includes incisors and canines.

Proximal surfaces are those that are adjacent to an adjacent tooth. When caries develop in these areas, they may not be visible from the front, making them somewhat different from the cavitations addressed in other classes. It's essential to accurately identify these lesions, as they often require restorative treatment that focuses on aesthetics as much as function.

Class I pertains to caries in pits and fissures, while Class V targets caries occurring on the gingival third of the facial or lingual surfaces of teeth. Class VI addresses caries on the incisal edges of anterior teeth or the cusp tips of posterior teeth.

Therefore, the classification of proximal caries in anterior teeth as Class III is essential for correct diagnosis and treatment planning in dental practice.
