Human gingival fibers and periodontal membrane fibers were observed scanning-electoronmicroscopically. The results obtained were as follows: 1) In the gingival fibers, the folds which are relatively similar in form cross at right-angle to the tooth and the extention of fibers between the cementum and the gingiva were observed. 2) The periodontal membrane fibers were generally consisted of the following three types; the first, relatively thick fibers which crossed between the cementum and the alveolar bone, the second, thin fibers which were observed mainly around the cementum and run parallel to the tooth, and the third, curtin-like close fibers which were located at the middle of the periodontal membrane and were observed streching like a spider's web in the strong magnification. 3) At the cementum, the ends of the periodontal membrane fibers of which brunch like roots and bury into the cementum were observed. 4) Some erythrocytes were observed on the cementum and the periodontal membrane fibers.
