What type of surfaces does GV Black's Class V concern?

GV Black's Class V cavity classification refers specifically to lesions found on the facial (buccal or labial) or lingual surfaces of teeth, particularly at the gingival third. These areas are typically prone to decay due to their location and exposure to plaque accumulation and other factors.

The focus on the facial surfaces in the gingival third aligns with the characteristics of Class V cavities, which are often the result of caries near the gum line, where hygiene can be challenging. This distinguishes Class V from other classes that address different tooth surfaces, such as incisal (Class I), occlusal (Class I), or interproximal (Class II) surfaces, which do not fall within the definition of Class V.

By understanding the specific attributes of Class V, dental assistants can better identify, treat, and educate patients about the importance of oral hygiene related to these vulnerable areas. Thus, the emphasis on facial surfaces near the gingival thirds is key to grasping the clinical relevance of this classification.
