| Outline of Final Research Achievements |
We are focusing on the mechanism of root formation damage caused by irradiation. It is not sure whether the direct damage of irradiation on the tooth germ is involved in failure of tooth formation in head irradiated mice. In the present study, we established the local irradiation method that irradiates only the molar tooth germ. We confirmed that irradiation only the molar tooth germ, and tooth root formation was disrupted.
This experimental model is useful for elucidating the mechanism of root formation damage caused by irradiation.
