| Outline of Final Research Achievements |
In this study, it was aimed for the alveolar bone regeneration with the osteogenic small chemical compound to regenerate of the irreversible bone defect part by periodontitis. Osteogenic helioxanthin-derivative (TH) incorporated the solution which let（2-Hydroxypropyl)-β-cyclodextrin(CD) include it into cellulose was made the gel. The gel had osteoblastic differentiation inducibility, and there was not the cytotoxicity. We made the rat model of periodontal disease that was near the natural development of the symptoms of periodontitis. After giving TH-containing gel using the rat model in the place where the defect of alveolar bone, predominance had few alveolar bone losses. There are not the cytotoxicity in vivo.
