Focal odontoblastic dysplasia: dentin dysplasia type III?

ABSTRACT

A new, nonsyndromic dentin defect, focal odontoblastic dysplasia, is described on the basis of clinical, radiographic, histologic, and scanning electron microscopic criteria. A provisional classification is proposed for this disease entity according to the nosology of Shields and associates. Four additional cases in the literature which possibly represent this new entity are presented, and a possible genetic etiology is discussed.
