Dentin dysplasia type Ⅱ (DD-Ⅱ) is an inherited dentin disorder that affects both the primary and permanent dentition. Genetic studies indicated that DD-Ⅱ can be caused by mutations in the dentin sialophosphoprotein gene (DSPP, 4q21, 3). Clinically, the affected primary teeth resemble those seen in dentinogenesis imperfecta. The permanent teeth appear essentially normal in color and morphology. Radiographically, a typical ”thistle tube”-shaped pulp chamber in the anterior teeth and reduced pulp chambers with a bow-tie outline in the molar teeth are observed. This report describes the clinical and radiographic features of DD-Ⅱ in a 6-year-old ethnic Chinese (Taiwanese) girl with a 4-generation family history.
