Abstract : 「抄録」 主として18~23歳の本学学生598名について甘好き甘嫌い, 軟食好き, 硬食好き, 温食好き, 温飲食をあまり口にしないという6群の飲食物の偏りとう蝕の発生率の関係を調べた. 実験の結果はう蝕の発生頻度は硬食物群を除けば温飲食物群が最も高く, 甘好み群がこれに次ぎ, 軟食群, 冷食群となり, 甘嫌い群が最も低い. われわれは調査の結果を次のように解釈したい. (1)う蝕の初期発生は細菌の産生物である酸によるエナメル質の無機物の脱灰と恐らく無関係であろう. (2)熱い飲食物によりエナメル質の有機質蛋白が先ず変性され, 変性された蛋白が始めて菌により破壊されることによつてエナメル質う蝕は始まるのであろう. この際う蝕の発生はエナメル質表面に存在する炭水化物の量の多少には無関係のようである.

Abstract : An inquiry test was undertaken on the types of food and drinks according to their tastes in conjunction with the count of their dental carieses as to 598 students of Kanagawa Dental College and Junior Woman's College of Dental Hygienists ranging mainly frcm 18 to 23 years in age. The count of carieses were made as to the six different food groups according to their tastes. These were groups of much-of-sweets, little-of-sweets, hard food, soft food, hot food and drinks, and cold food. The average count of carieses was, except for the hard food group, the highest in the hot food group which was followed by the much-of-sweets group, soft food group, cold food group, and little-of-sweets group in order. The figures appeared in the present study might be interpreted by the authors suggesting the inception of enamel carieses being not due to bacterial producing acid decalcification, and the inception of enamel carieses to be probably the degradation of the keratinoid protein of the organic enamel matrix due to the hot food or drinks, which is followed by breakdown of the degraded proteins of enamel by bacteria, the proteolysis being indepent of the amount of carbohydrate attached to the enamel surface.
