Study Notes
Caries Classifications
-
Class 1 Caries: Involves the occlusal surfaces of posterior teeth, and affects the occlusal two-thirds of the buccal and lingual surfaces of molars, as well as the lingual surfaces of maxillary incisors.
-
Class 2 Caries: Occurs in posterior teeth and involves mesial-occlusal (MO), distal-occlusal (DO), or mesial-distal-occlusal (MOD) surfaces.
-
Class 3 Caries: Affects anterior teeth, specifically targeting the mesial or distal surfaces.
-
Class 4 Caries: Involves anterior teeth with decay present on the mesio-incisal (MI) or diisto-incisal (DI) surfaces.
-
Class 5 Caries: Can occur on any tooth, presenting on the gingival third of either the lingual or buccal/labial surfaces.
-
Class 6 Caries: Affects any tooth, specifically involving the occlusal cusp, ridge, or incisal edge, often signifying severe wear.
