Study Notes

Cavity Classifications

Class I Cavity: Involves pits and fissures on anterior and posterior teeth, specifically premolars and molars.
Class II Cavity: Affects proximal surfaces of posterior teeth, usually molars and premolars, and often includes the occlusal surface.
Class III Cavity: Found on the proximal surfaces of anterior teeth, such as mesial and distal surfaces, without affecting the incisal angle.
Class IV Cavity: Similar to Class III but involves the incisal angle of anterior teeth.
Class V Cavity: Located on the cervical third of the facial or lingual surface of any tooth.
Class VI Cavity: Occurs on the incisal edges of anterior teeth and the cusp tips of posterior teeth, generally due to abrasion.

Cavity Types

Simple Cavities: Cavities affecting only one surface of a tooth.
Complex Cavities: Involve two or more surfaces of a tooth, indicating a more extensive area of decay.

Class I Cavity Specifics

Affects occlusal surfaces of both premolars and molars.
Involves occlusal two-thirds of buccal and lingual surfaces on posterior teeth.
Found in the lingual pits of anterior teeth, particularly at the cingulum.
Located in the incisal two-thirds of labial and lingual surfaces on anterior teeth.

Class II Cavity Specifics

Occurs on proximal surfaces between posterior teeth, emphasizing mesial and distal areas.

Class III Cavity Specifics

Located on proximal surfaces of anterior teeth, explicitly excluding the incisal edge.

Class IV Cavity Specifics

Found on proximal surfaces of anterior teeth, including the incisal edge.

Class V Cavity Specifics

Positioned in the gingival one-third of labial, lingual, and buccal surfaces across all teeth.

Class VI Cavity Specifics

Manifests on incisal edges of anterior teeth and the tips of cusps on posterior teeth.
