Outline of Final Research Achievements |
It's reported that the biofilm which exists outside the root apex participates in refractory apical periodontitis. So we developed extraradicular biofilm model in rats. In this research, we tried to development new model that pulls out gutta-percha point and investigated the effects of gutta-percha point on periapical lesions. We succeeded in development of new model that pulls out gutta-percha point using instrument for micro endodontics. And it became clear that gutta-percha point doesn't influence periapical lesion size.
