Dentin malformation with alveolar bone loss and periapical abscess formation.

Pediatric Dentistry – 21:2, 1999 Abnormalities of dentin formation have been classified into two large categories: those that are primarily diseases of the dentin itself and those in which the dentin defect accompanies defects in other tissue systems. For example, the former category contains dentin dysplasia types I and II, dentinogenesis imperfecta types II and III and regional odontodysplasia, while the latter contains osteogenesis imperfecta (dentinogenesis imperfecta type I) and X-linked hypophosphatemic vitamin D-resistant rickets (XLH) 2, Characteristic defects of the dentin are found in each disease. However, there are some cases difficult to diagnose because of a dearth of documented case reports for comparison, some confusion in the published literature or an in-definite manifestation of symptoms. This report presents a rare case of dentin malformation with periapical abscess formation and alveolar bone loss.
