The use of tricalcium phosphate to preserve alveolar bone in a patient with ectodermal dysplasia: a case report.

The prosthodontic management of the child with ectodermal dysplasia is made difficult because of the under-development of the alveolar ridges. This paper describes a case where tricalcium phosphate was placed in sockets immediately following the extraction of the primary incisor teeth to help maintain alveolar bone width, offering a valuable alternative treatment option in the prosthodontic management of the child patient with ectodermal dysplasia.

Dentinal dysplasia type I: report of a case.

A case of dentinal dysplasia type I is presented. This rare hereditary disturbance of dentine is characterized by short-rooted teeth with sharp conical apical constrictions, aberrant growth of dentine in the pulp chamber leading to reduced pulp space in permanent teeth and total pulpal obliteration in the primary dentition. Clinical, radiographic and histopathological material from a 7-year-old boy, showing the typical features of this disorder in which teeth are prematurely lost through periapical abscesses, cysts or spontaneous exfoliation, is described.

Bizarre parosteal osteochondromatous proliferation in the anterior maxilla: report of a case.

Bizarre parosteal osteochondromatous proliferations are a rare subgroup of the osteochondromatous lesions. They must be differentiated from reactive osteochondromatous proliferations, low grade parosteal osteogenic sarcoma, and chondrosarcoma. Their recognition is important from the point of view of management, which should be by simple excision.
