Black classification of Cavities Flashcards
Class I
Decay is diagnosed in the pits and fissures of the occlusal surfaces of molars and premolars, buccal or lingual pits of molars, and lingual pits of maxillary incisors.
Because most of this type of decay is confined to a small area, the dentist will choose to restore these surfaces with composite (tooth-colored) resins.
Class II
Decay is diagnosed in the proximal (mesial or distal) surfaces of premolars and molars.
-Restoration design most likely includes occlusal surfaces and may involve more than two surfaces
Type of dental material used is amalgam or composite (tooth-colored) resins. If the tooth has extensive decay, the dentist may choose to crown the tooth with a gold or porcelain inlay, onlay or crown.
Class III
Decay is diagnosed in the proximal (mesial or distal) surfaces of incisors and canines (anterior teeth)
dental material used to restore: composite (aesthetics)
Clas IV
Decay is diagnosed in the proximal (mesial or distal) surfaces of incisors and canines.
Difference between class 3 and 4 is, 4 involves the incisal edge or angle of the tooth.
composite or porcelain crown (if extensive damage)
Class V
Decay is diagnosed in the gingival third of facial or lingual surfaces of any tooth. Also referred to as smooth surface decay.
silver amalgam if posterior teeth, composite if anterior teeth
Class VI
Decay is diagnosed on the incisal edge of anterior teeth and the cusp tips of posterior teeth.
Caused by abrasion (wear) and defects.
