  • Anadontia: a complete absence of one or both dentition. Hypodontia: one or several teeth are missing. Hyperdontia: There are teeth additional to those of the the normal series.
  • The dental chamber has a greater apico-occlusal height than in normal teeth, with no constriction at the level of the amelocemental junction with the result that the chamber extends apically well beyond the cervix.
  • A deformity in which the crown of the tooth is displaced from its normal alignment with the root, so that the tooth is severely bent along its long axis. Dilaceration is usually the result of acute mechanical trauma and most frequently involves the maxillary incisor.
