Study Notes

Class I

Class I decay occurs in pits and fissures of occlusal surfaces of molars/premolars, as well as buccal or lingual pits of molars and lingual pits of maxillary incisors.
Class I restoration typically involves amalgam or composite resins, with material choice based on lesion location and required strength.

Class II

Class II decay affects the proximal (mesial or distal) surfaces of premolars and molars, often requiring radiographs for detection.
Restoration options for Class II include strong silver amalgam or tooth-colored composite, with extensive decay potentially requiring gold or porcelain inlays, onlays, or crowns.

Class III

Class III decay impacts the proximal surfaces of incisors and canines, similar to Class II but easier to access and less tooth structure is affected.
Restoration for Class III utilizes composite resins, focusing on esthetic appearance.

Class IV

Class IV decay also involves proximal surfaces of incisors and canines but includes the incisal edge, differentiating it from Class III.
Restoration often uses composite resins for esthetics, with porcelain crowns considered for extensive decay.

Class V

Class V decay is located on the gingival third of the facial or lingual surfaces of any tooth, known as smooth surface decay or gum line decay.
Restoration choices depend on the tooth type; amalgam is preferred for posterior teeth, while composite is used for anterior teeth.

Class VI

Class VI decay manifests on the incisal edges of anterior teeth and cusp tips of posterior teeth, typically caused by abrasion or defects.
Restoration for Class VI emphasizes composite resins for an appealing esthetic finish.
