| Outline of Final Research Achievements |
The aim of this study was to investigate the effect of flavonoids on orthodontic tooth movement and root resorption caused by it. It equipped with the closed coil spring of upper incisor part alveolar bone of a mouse, and between the first molar of left hand side, and carried out tooth movement. Typical three flavonoids known as related to bone metabolism and anti-inflammatry were selected and medicated to local area. 12days afterward, the distance between the second molar were measured by μCT. After extraction, root resorption was assessed by scanning electron microscopy on the pressure side of the mesial side of distobuccal root of the first molar. In each flavonoid medication group and the control group, the significant difference was not observed in the amount of tooth movements and root resorption. However, since optimal quantity of each flavonoid is unknown, it seems first that examination is required about optimal given dose and opitimal orthodontic force from now on.
