A Class V cavity is characterized by caries affecting which part of the teeth?

• A. Facial or lingual surfaces of all teeth
• B. The incisal edges of anterior teeth
• C. The proximal surfaces of molars
• D. The occlusal surfaces of molars

Answer: (A)

A Class V cavity specifically refers to carious lesions that are found on the facial (buccal) or lingual surfaces of all teeth, which includes both anterior and posterior teeth. This classification is important in dental practice as it indicates the location of the decay, helping dental professionals determine the appropriate treatment approach. Class V cavities can occur in areas where the enamel is often thinner or more susceptible to decay, such as near the gum line, particularly in patients with poor oral hygiene. The other options refer to different classifications of cavities. For instance, incisal edges are associated with anterior teeth and fall into a different cavity classification that typically includes the edges rather than the surfaces mentioned in the correct answer. Proximal surfaces of molars and occlusal surfaces also relate to different areas where caries can occur, each designated as Class II and Class I cavities, respectively. Understanding these classifications helps in diagnostics and in planning restorative procedures for various types of cavities.
