| Outline of Final Research Achievements |
The purpose of this study was to elucidate the pathogenesis of malocclusion by focusing on inferior growth of the anterior cranial base and the nose in BALB/c-bm/bm mouse which spontaneously induces malocclusion.As begin this study, BALB/c-bm/bm mouse was infected the Pasteurella pneumotropica.Therefore, it was decided to try creating a new animal model.Parathyroid hormone (PTH) and parathyroid hormone-related peptide (PTHrP) play an important role in the differentiation and the formation of cartilage.So, it was succeeded to create a new animal model which have a variant PTH / PTHrP receptor, gene mutations have been inserted in the DNA sequence.
In the future, it is planned to evaluate the histological findings of bone and cartilage at the nasal septal cartilage in embryonic and masticatory performance using variant PTH / PTHrP receptor mouse and BALB/c-bm/bm mouse which spontaneously induces malocclusion.
