Class 3 in Black's classification is characterized by which type of cavities?

• A. Cavities on the incisal edge of anterior teeth
• B. Cavities involving the mesial or distal on an anterior tooth
• C. Cavities involving the cervical margin of any tooth
• D. Cavities involving at least two surfaces of a posterior tooth

Answer: (B)

In Black's classification of cavities, Class 3 is specifically defined as cavities that occur on the proximal surfaces of anterior teeth, which includes the mesial and distal surfaces. This is significant because it highlights how decay can develop between teeth, areas that are often less accessible for cleaning and may go unnoticed. Class 3 cavities do not affect the incisal edge, cervical margin, or involve multiple surfaces of posterior teeth, which distinguishes them from other classes in Black's classification. Understanding the classification helps dental professionals identify the location and extent of dental caries, guiding treatment decisions effectively.
