Abstract : In our endodontic treatment, we usually confirm the germfree state at root apex before root canal filling using the Chair-side anaerobic incubation system. In this time, we recalled 250 cases after 1 to 3 years. As a result, 98.8% of the cases were progressing favorably after root canal filling. Bacteria were isolated from the rest of cases (3 cases) which showed clinical symptoms or radiolucency at root apex. These results strongly indicate that the Chair-side anaerobic incubation system is necessary for endodontic treatment.
