我が教室に於ける歯槽濃漏症に関する研究 総括

Studies were made on 327 pyorrhea alveolaris cases, 16-29 years of age, who had been found out of 2496 healthy unmarried women with the following results: (1) Pyorrhea alveolaris was found in 13% of them with increasing positive rates in advancing age. (2) Inflammatory type was found in 69% , combined type 29% , and atrophic type 1% with a general trend of mildness. (3) Traumatic occlusion was found in 10.4% . (4) The capillaries of nail grooves in pyorrhea alveolaris cases are very often abnormal in their arrangement, winding and thickness. (5) Pyorrhea alveolaris cases were found in 81% of uterine hypoplasia cases due to hormone disturbances. (6) R.B.C., W.B.C., hemoglobin, E.S.R., and red corpuscle resistance of pyorrhea alveolaris case, were normal; reticulocytes were slightly decreased, acidophil leucocytes were slightly increased, blood sugar was the maximum with in a normal range, γ-globulin in serum widely ranged, respiration of the R.B.C. slightly diminished, and cholinesterase of the R.B.C. and plasma slightly decreased. (7) Function of the reticuloendothelial system was decreased. (8) Basal metabolism, slightly elevated, being +12.60% on an average. Specific dynamic function of proteins was clearly decreased in 70% of the patients observed. (9) Gingivae of pyorrhea alveolaris cases showed three times increase in histamine. (10) On improvement of pyorrhea alveolaris, the lesser appearance of acidophils, degenerated epithelia, and spirochetae was observed in the exudate of gingival pockets with the appearance of the more nnmbers in small phagocytes and lymphocytes. (11) Iodine preparations, chlorophyl agents, local and general external application of vitamin K were found favorable in treating pyorrhea alveolaris.
