Study Notes
Class I Cavities
- Found in pits and fissures of teeth
- Occur on occlusal surfaces of posterior teeth (premolars and molars)
- May appear in buccal or lingual pits on molars
- Includes lingual pit near the cingulum of maxillary incisors
Class II Cavities
- Located on proximal surfaces (mesial or distal) of posterior teeth
- Typically affect premolars and molars
Class III Cavities
- Affect interproximal surfaces (mesial or distal) of anterior teeth
- Involves canines, lateral incisors, and central incisors
Class IV Cavities
- Occur on interproximal surfaces of anterior teeth
- Include involvement of the incisal edge
Class V Cavities
- Present on the cervical third of facial or lingual surfaces
- Often caused by candy or sweet consumption
Class VI Cavities
- Characterized by wear on incisal or occlusal surfaces
- Caused by abrasion leading to cavities
