title: Radiographic manifestations of an unusual combination Types I and Type II dentin dysplasia.
abstract: Dentin dyslasia is a rare autosomal dominant hereditary variant of dentinogenesis imperfecta. The primary defect is mesodermal and involves the dentin. Two types (Type I and Type II) of dentin dysplasia have been described previously. The current case presents radiographic findings which include characteristics common to both types. It is proposed that either a third type (Type III) be recognized or the variability of the developmental defect precludes definitive subclassification.
