Which GV Black's class describes cavities located on the buccal or lingual surfaces near the gingival thirds?

GV Black's classification system categorizes tooth cavities based on their location. Class V cavities specifically refer to those that occur on the buccal (outer cheek side) or lingual (inner tongue side) surfaces of teeth, particularly near the gingival third, which is the area closest to the gum line. This classification helps dental professionals accurately communicate about the nature and location of dental caries (cavities) and therefore informs treatment approaches.

Understanding that Class V lesions are most often associated with areas subject to plaque accumulation and less likely to be associated with chewing forces forms an important part of dental education. This is distinct from other classes in the GV Black system, which describe cavities in locations such as the proximal surfaces of posterior teeth (Class II) or the incisal edges of anterior teeth (Class IV). Class VI refers to cavities on the cusp tips of posterior teeth and the incisal edges of anterior teeth, which are not relevant to the surfaces mentioned in the question.
