目的：本研究的目的是评估拥有20颗或更多天然牙齿的老年人是否比拥有少于20颗牙齿的老年人更有可能活得更长。材料与方法:老年人超过80岁的男性和35女性(24)与20或更多的牙齿(>或= 20组)与老年人相比(24男性和35岁女性)用不到20的牙齿(或= 20组(平均+ / - SE齿齿数男性23.9 + / - 0.6;雌性,23.8 + / - 0.4)相比还是= 20组或= 20组明显累积生存率(p < 0.05)高于或= 20组
OBJECTIVES: The objective of this study was to assess whether elderly people with 20 or more natural teeth were more likely to live longer than a cohort with less than 20 teeth.MATERIALS AND METHODS: Groups of elderly people over 80 years of age (24 males and 35 females) with 20 or more teeth (>or=20 group) were compared with elderly people (24 males and 35 females) with less than 20 teeth (or=20 group (average +/- SE tooth number of teeth - males, 23.9 +/- 0.6; females, 23.8 +/- 0.4) was compared with the or=20 group or or=20 group had a significantly higher cumulative survival rates (p < 0.05) than the or=20 group and
