 note = {The subjects in this study were 372 adults living in Yasuda town, Niigata prefecture. Those were the same as in the first report. The relation between masticatory ability and number of missing teeth and the effect by using removable dentures were investigated in this report. First as subjective evaluation of masticatory ability, the subjects were asked about their ability to chew foods on the evaluation chart of masticatory efficiency with complete dentures by Yamamoto (Yamamoto's chart for short). Secondly as objective evaluation of masticatory ability, the amount of sugar elution from a chewing gum was measured after they had chewed a chewing gum 100 times. In the subjective evaluation of masticatory ability it became difficult for them to chew hard foods on the Yamamoto's chart with increasing number of missing teeth, and the kind of foods which could be chewed by the 8～14 missing teeth group of subjects widely differed from that by the 1～7 missing teeth group. Each of foods on the Yamamoto's chart was scored as follows : can be chewed (○) -2points, can be chewed by force or when chopped fine(△) -1point, cannot be chewed (×) -0point. The total score of each subject was defined as self-assessed score. It decreased with increasing number of missing teeth. The result of objective evaluation of masticatory ability was that the amount of sugar elution decreased with increasing number of missing teeth. But its decreasing trend was gentle as against self-assessed score which decreased sharply on the 15～21missing teeth group. The subjects using removable dentures were asked about their ability to chew foods on the Yamamoto's chart both with dentures and without dentures. It became difficult for them to chew hard foods with increasing number of missing teeth in the case without dentures. However their masticatory ability recovered fairly in the case with dentures. But even in the case with dentures most of them could not chew hard foods on the Yamamoto's chart., 第1報で分析の対象となった新潟県北蒲原郡安田町在住の成人372名を調査対象として,咀嚼能力と喪失歯数との関連,および義歯使用の影響について分析,検討した｡まず咀嚼能力の主観的評価法として,山本式総義歯咀嚼能率判定表(以下, 咀嚼能率判定表と略す)に従って,食品摂取可能状況を質問するものとした｡次に客観的評価法として,チューインガムを一定回数かませ,ガムより溶出した糖の重量を測定することによって, 咀嚼能力を評価する方法を採用した｡主観的評価法による咀嚼能力については,喪失歯数が増加するに従って, 咀嚼能率判定表で咀嚼難易度の高い食品がかみにくくなる傾向があった｡また喪失歯が8～14歯で, 咀嚼可能な食品の種類が大幅に変化する傾向が認められた｡さらに,28食品の数値化による合計点を求め,これを自己評価得点とし,喪失歯数との関連を検討した結果,喪失歯数の増加に伴い, 自己評価得点が減少する傾向が認められた｡客観的評価法による咀嚼能力については,喪失歯数の増加に従って,溶出糖量が減少し, 咀嚼能力が低下していく傾向が認められた｡しかし減少の傾向は,自己評価得点の場合よりやや緩やかで,喪失歯が15～21歯以上から大きな減少となった｡義歯使用者については, 咀嚼能率判定表に従って,義歯使用時と非使用時における食品摂取可能状況を回答してもらった｡その結果,義歯非使用時には,喪失歯数の増加に伴い, 咀嚼難易度の高い食品がかみにくくなる傾向があった｡一方,義歯使用時には, 咀嚼能力は相当回復するものの, 咀嚼難易度の高い食品はほとんどかめないと判断しており,義歯による咀嚼能力の回復には,食品の種類において限界があることが示唆された｡},
