抄録

口腔内の問題で受診した300人の患者を対象に、口腔内原虫の頻度を調査した。Entamoeba gingivalisはTrichomonas tenaxよりも高い頻度で培養分離された（50.7％対28％）．原虫で最も高い頻度を示した年齢層は，アメーバでは30-34歳，鞭毛虫では45-54歳であった．内膜症はOHIS指数に関連して漸増した。Trichomonas tenaxは歯周病が深い場合に3倍以上の頻度で検出され，Entamoeba gingivalisは歯肉炎で最も高頻度に検出された．これらの相関関係から，これらの原虫の病原性について考察し，いくつかの治療的論拠を示した．

The oral protozoa frequency has been studied in 300 patients consulting for oral problems. Entamoeba gingivalis has been isolated more frequently in culture than Trichomonas tenax (50.7% against 28%). The age range which showed the highest frequency in protozoa was the 30-34 year old group for the amoeba and the 45-54 year old group for the flagellae. The endemia increased progressively in relation to the OHIS index. Trichomonas tenax is three times more frequent in case of deep periodontal diseases whereas, Entamoeba gingivalis reached its highest frequency in the case of gingivitis. The pathogenic potentials of these protozoa have been discussed in the light of these correlations and some therapeutical arguments.
