Regional odontodysplasia (ghost teeth)

This is an uncommon developmental disorder of unknown aetiology associated with abnormalities of enamel, dentine, pulp, and the dental follicle. Both deciduous and permanent dentitions are affected and the number of teeth and number of quadrants involved varies. The defect occurs most frequently in the anterior part of the maxilla and is usually unilateral.

Clinical features:

  • The teeth are delayed in eruption
  • Small underdeveloped teeth
  • Pitted tooth surface
  • generally have a very irregular shape with hypoplastic and irregularly mineralized enamel
  • the dentine is thinner than normal, hypomineralized, and contains large areas of interglobular dentine

Radiological examination:

  • shows reduced radiopacity of the teeth with loss of distinction between the enamel and dentine, described as a ‘ghostly’ appearance (Fig.).
  • Treatment generally involves managing the symptoms as they develop
  • If a tooth needs to be removed than a prosthetic will be needed to ensure the jaw develops normally
