Study Notes
Class I Cavity
- Involves decay in pits and fissures of molars and premolars, as well as buccal or lingual pits of molars and lingual pits of maxillary incisors.
- Restoration materials include amalgam and composite resins, depending on lesion location and required strength.
- Key areas affected include occlusal, buccal, or lingual pits and fissures.
Class II Cavity
- Decay occurs on proximal surfaces (mesial or distal) of premolars and molars.
- Detection often requires radiographs due to the difficulty in visual examination.
- Restoration typically involves silver amalgam for strength or composite resins for esthetic appeal.
- Restoration design includes occlusal and proximal surface areas.
Class III Cavity
- Affects proximal surfaces (mesial or distal) of incisors and canines, similar to Class II but in anterior teeth.
- Easier access for dentists with less tooth structure affected compared to Class II.
- Restoration materials consist primarily of composite resins for esthetic purposes.
Class IV Cavity
- Involves decay on proximal surfaces of incisors and canines, including the incisal edge or angle.
- Similar restoration materials to Class III, predominantly using composite resins for esthetic appearance.
- Extensive decay may require porcelain crowns for restoration.
Class V Cavity
- Diagnosed in the gingival third of the facial or lingual surface of any tooth; known as smooth-surface decay.
- Restoration material choice varies: silver amalgam for posterior teeth and composite resins for anterior teeth.
- Key location is the gingival one-third of buccal or lingual surfaces, often at the gumline.
Class VI Cavity
- Occurs on incisal edges of anterior teeth and cusp tips of posterior teeth.
- Resulting from abrasion and defects.
- Restoration materials are primarily composite resins for their aesthetic appeal.
- Key locations affected are the cusps of occlusal surfaces and incisal edges of anterior teeth.
