| Outline of Final Research Achievements |
The purpose of this study was to investigate dental problems related to skeletal diseases with basic and clinical approaches. A nationwide dental survey revealed that dentinogenesis imperfecta is a major dental problem occurring in 60% of patients affected by osteogenesis imperfecta. In those patients, a permanent successor often emerges into the oral cavity without resorption of the root of the corresponding primary tooth due to dislocation by that successor. However, the present survey found that bisphosphonate treatment does not need to be interrupted in such cases when the primary tooth is extracted. Early exfoliation was recognized in not only primary but also permanent teeth in a patient with hypophosphatasia. In another hypophosphatasia patient who received enzyme replacement therapy 1 day after birth, cementum formation was detected. Furthermore, gene therapy was demonstrated to improve dental manifestations in model mice with hypophosphatasia.
