Study Notes
Cavity Classifications
-
Class 1 cavity occurs in pits or fissures on the occlusal surfaces of molars and premolars, as well as on the facial and lingual surfaces of molars, including the lingual surfaces of maxillary incisors.
-
The surfaces involved in Class 1 are clinically visible, such as occlusal, lingual, and buccal surfaces of posterior teeth.
-
Class 2 cavity is found on the interproximal surfaces of posterior teeth, requiring MOD or MO restoration.
-
These surfaces are not clinically visible, making them significant for dental treatment planning.
-
Class 3 cavity affects the interproximal surfaces of anterior teeth, specifically located on the mesial and distal surfaces only.
-
Class 3 cavities are also not clinically visible, emphasizing the importance of regular dental checkups.
-
Class 4 cavity involves interproximal surfaces of anterior teeth but extends to the incisal edge.
-
This type is considered a larger version of Class 3, impacting the incisal angle and requiring careful restoration.
-
Class 5 cavity is positioned on the gingival third or cervical area of the tooth, particularly along the facial or lingual surfaces.
-
This area is often referred to as the neck of the tooth and is crucial in preventing periodontal issues.
-
Class 6 cavity encompasses any dental situation that does not fit into Classes 1-5, typically involving cusp tip pits on canines and molars.
-
This classification allows for broader recognition of diverse cavity forms in dental practice.
