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.
