目的：本研究的目的是揭示社区老年人在70岁时牙齿和咬合支持的进一步丧失以及咀嚼能力改变的差异是否取决于70岁时的牙列状况。方法：对349名老年人(女性176名，男性173名)进行了10年的纵向调查。研究对象按照宫内氏三角分类的方法分为四组。A区：有十个或更多咬合支撑物的受试者。B区：有9至5个咬合支撑物的牙合。D区：有四个或更少的咬合支撑体和11个或更多剩余牙齿的人。C区：剩余牙齿少于或等于10颗的牙齿。两次检查均记录剩余牙齿数和咬合支撑量。结果：B区老年人牙齿缺失多于A区和C区老年人，B区和D区老年人的咬合支撑力损失明显大于A区和C区老年人，A区老年人和B区老年人的咀嚼食物数量明显减少。结论：社区老年人70岁时以Miyachi‘s三角分类法划分的不同牙列状态导致10年后剩余牙数、咬合支撑力和咀嚼能力的变化。(C)2016年日本口腔修复学会。爱思唯尔有限公司出版。
Purpose:' The aim of this study was to reveal whether the differences in further loss of teeth and occlusal supports, and change in masticatory ability depend on the status of dentition at the age of 70 in community-dwelling elderly people.Methods: A 10-year longitudinal survey was carried out on 349 (176 females and 173 males) elderly subjects. The subjects to be analyzed were classified into four groups in accordance with the classifications of Miyachi's Triangular Classification. Zone A: subjects with ten or more occlusal supports. Zone B: those with nine to five occlusal supports. Zone D: those with four or fewer occlusal supports and 11 or more remaining teeth. Zone C: those with ten or fewer remaining teeth. The numbers of remaining teeth and occlusal supports were recorded in both examinations. Questionnaires regarding their food intake status were given to subjects.Results: Subjects in Zone B had greater numbers of teeth loss than those in Zones A and C. Subjects in Zone B and D lost greater numbers of occlusal supports than subjects in Zones A and C. The number of food items that could be chewed had significantly decreased in subjects who remained in Zone A and those who changed from Zone B to Zones D and C.Conclusions: It was shown that various states of dentition classified by Miyachi's Triangular Classification at the age of 70 resulted in different numbers of remaining teeth and occlusal supports and changes in masticatory ability 10 years later in community-dwelling elderly people.
