| Outline of Final Research Achievements |
This study investigated the efficacy of oxygen nanobubble water to encourage proper healing of traumatized teeth. In the beginning of this study, previous studies about nanobubble water reported its bioactive effect by the increase of survival rate etc, and the mechanism to living organisms was not fully elucidated. Additionally, renovation of our animal laboratory building was postponed. Therefore, our initial experiment plan required significant change, and we inspected the effect of nanobubble water on human oral tissue as a previous step of therapeutic application of nanobubble water to traumatized teeth. Oxygen and air nanobubble water inhibited the proliferation of human dental follicle stem cells in vitro. However, comprehensive elucidation of the effects of air and oxygen nanobubble water on oral tissue and living organisums will require further investigation both in vitro and in vivo.
