Class III caries in Black's classification is defined as?

In Black's classification of caries, Class III caries specifically refers to decay that occurs on the proximal surfaces of anterior teeth, which are the front teeth, including incisors and canines. This classification indicates that the caries affects the surfaces that are adjacent to neighboring teeth, and it is critical for dental professionals to identify and treat these types of cavities effectively to maintain the aesthetic and functional integrity of anterior teeth.

The other classifications describe different types of caries. For example, caries on the incisal edge pertains to Class I, affecting the biting surfaces where occlusion occurs. Class II involves the proximal surfaces of posterior teeth, while Class V refers to caries occurring on the gingival third of any tooth. Understanding these categories allows dental professionals to categorize caries properly and determine the best treatment approach based on the location and extent of the decay.
