Flashcards
Class I Cavity
Class I Cavity
Pit and fissure cavities found on the occlusal surfaces of molars and premolars, or buccal/lingual surfaces of molars.
Class II Cavity
Class II Cavity
Posterior teeth cavities that occur on the interproximal surfaces (mesial or distal) and involve more than one wall of the tooth.
Class III vs. Class IV
Class III vs. Class IV
Class III cavities are on the interproximal surfaces of anterior teeth and do not involve the incisal edge, while Class IV cavities do involve the incisal edge.

Study Notes
Tooth Classifications
-
Class I: Involves pit and fissure cavities; can occur on the lingual side of anterior teeth or the occlusal/buccal surfaces of posterior teeth; located on the top third of the tooth; never found on the mesial or distal sides.
-
Class II: Exclusively pertains to posterior teeth; cavity is interproximal and can involve missing more than one wall (mesial/distal or mesial/occlusal/distal); requires radiographs (bitewing) for detection; fillings are typically done with composite or amalgam.
-
Class III: Applies only to anterior teeth; cavities can be interproximal but do not extend to the incisal edge.
-
Class IV: Similar to Class III but specifically involves the incisal edge of anterior teeth.
-
Class V: Represents smooth surface decay found on the cervical third of the tooth; occurs on facial or lingual surfaces of both anterior and posterior teeth; does not affect pit and fissure areas; when decay is below the cemento-enamel junction (CEJ), it is identified as a root caries.
-
Class VI: Refers to decay affecting the entire incisal edge of anterior teeth or the cusp of posterior teeth.
