Survey of dental health condition was performed at a special nursing home for the elderly with senile dementia (28 subjects, 83.3 +/- 6.8 year-old; SD group) or without senile dementia (68 subjects, 84.6 +/- 7.2 year-old; NSD group). There was no difference in number of teeth survived between SD and NSD groups. However, the elderly in SD group had more unfunctionable and/or unrestorable teeth (C4) and less sound and filled teeth (SFT) than those in NSD group. Number of teeth of the elderly in 85- to 89-year-old group was smaller than those of not only younger but older age groups, irrespective of senile dementia. Lower canines showed the highest survival rate among all kinds of teeth in SD as well as in NSD group.
在一家专门的养老院对患有老年痴呆症的老年人（28名受试者，83.3±6.8岁；SD组）和未患老年痴呆症的老年人（68名受试者，84.6±7.2岁；NSD组）进行了口腔健康状况调查。SD组和NSD组的存留牙齿数量没有差异。然而，与NSD组相比，SD组的老年人有更多无法正常使用和/或无法修复的牙齿（C4），健全和已填充牙齿（SFT）更少。无论是否患有老年痴呆症，85至89岁组老年人的牙齿数量均少于较年轻和较年长的年龄组。在SD组和NSD组中，下尖牙在所有类型的牙齿中存活率最高。
