When treating serious periodontal diseases, remedies that only treat inflammation caused by bacterial plaque often fail to achieve satisfactory results.
Therefore, it is necessary to properly determine etiologic factors before treatment. In 1952, Waehauge described conditions of inflammation generally observed in periodontal diseases as “there is inflammatory cell infiltration within the range of 1 mm to 2 mm from the border of plaque.” However, inflammation is often observed beyond 2 mm from the attachment of plaque. In such cases, brushing or initial treatment is often ineffective.
Cases of periodontal diseases in which circulation inhibitors were greatly involved are presented, and the periodontal treatment and occlusion provided by prostheses were discussed.
