title: [Cleidocranial dysplasia--histological findings in the dental cementum].
abstract: Up to now only very few reports on histological studies of teeth in cleidocranial dysplasia have been published. We are presenting a 12-year old boy with this syndrome. Seven of his teeth were studied microscopically. The most relevant results are as follows: acellular cementum in all teeth, almost complete missing of cellular cementum, normal intermediate cementum. The pathogenesis of the retarded eruption of teeth in this disorder is explained as a result of eburnation of the alveolar bone as well as fibrosis of the gingiva. The therapy of choice in order to stimulate eruption is a rigid orthodontic treatment of the impacted teeth using fixed appliances.
