Cleidocranial Dysplasia and Dental Health

Cleidocranial dysplasia (cleido = collar bone, + cranial = head, + dysplasia = abnormal forming) is a rare skeletal dysplasia also known as Cleidocranial Dysostosis and Marie-Sainton Disease, characterized by short stature, distinctive facial features and narrow, sloping shoulders caused by defective or absent collarbones (clavicles).

Major symptoms may include premature closing of the soft spot on the head (coronal), delayed closure of the space between the bones of the skull (fontanels), narrow and abnormally shaped pelvic and pubic bones and deformations in the chest (thoracic region). Delayed eruption of teeth, moderately short stature, a high arched palate, a wide pelvic joint, failure of the lower jaw joints to unite, and fingers that are irregular in length may also be present. Cleidocranial dysplasia is inherited as an autosomal dominant genetic trait.

  • What kinds of problems might be experienced? There is no link between anything the mother did or did not do while she was pregnant and the occurrence of Cleidocranial Dysplasia. It is transmitted as an autosomal dominant trait. The cause is not yet known, but several chromosome abnormalities have been linked with this syndrome, including chromosome 6p21. Protruding jaw (mandible) and protruding brow bone (frontal bossing)

  • Wide nasal bridge due to increased space between the eyes (hypertelorism)

  • High arched palate or possible cleft palate

  • Scoliosis of the spine
