National Board Dental Hygiene Examination Part B - Exam Topics Sample Questions

A Class VI restoration is present on tooth #14.  Which of the following is correct for the GV Black Cavity Classification of this restoration? 

Correct Answer:
includes the cusp tip of posterior teeth
to answer the question about the gv black cavity classification for a class vi restoration on tooth #14, it's essential to understand the specifics of the classification system developed by dr. g.v. black. this system is used to categorize the types and locations of cavities based on their position in the tooth and the type of tooth affected. the classifications range from class i to class vi, each describing different tooth surfaces and types of decay.

class vi restorations specifically include the cusp tips of posterior teeth (such as molars and premolars) and the incisal edges or angles of anterior teeth (such as incisors and canines). these areas are prone to wear and mechanical abrasion, as well as carious lesions. given that tooth #14 is a maxillary first molar, a posterior tooth, this classification correctly applies to the restoration if it involves the cusp tip of the tooth.

the other options in the gv black cavity classification are as follows: - class i includes all pits and fissures on the occlusal surfaces of molars and premolars, buccal or lingual pits of molars, and lingual pits of maxillary incisors. - class ii includes the proximal surfaces of premolars and molars, typically involving surfaces that are adjacent to another tooth. - class iii includes the proximal surfaces of incisors and canines that do not involve the incisal angle. - class iv includes the proximal surfaces of incisors and canines that do involve the incisal angle. - class v involves the gingival third of the facial or lingual surfaces of any tooth, typically not extending to the occlusal or incisal edge.

therefore, for tooth #14, a class vi restoration involving the cusp tip is correctly identified. this type of restoration is particularly aimed at addressing wear or caries that affect these high-stress areas of the teeth, which are significant for their role in chewing and grinding food.
