To prospectively study how dental status with and without dentures could become a predictor of overall mortality risk.
Five thousand six hundred eighty-eight community residents over 40 years old in the Miyako Islands, Okinawa Prefecture, Japan, were followed up for 15 years from 1987-2002.
We found that female subjects with less than 10 functional teeth and without dentures showed a significantly higher mortality rate than those with dentures. There was no significant difference of mortality rates in male subjects. There were no significant differences of mortality rates between subjects with 10 or more functional teeth with and without dentures.
The present study suggests that dentures are one of the factors associated with mortality rates especially in female subjects with less than 10 functional teeth.
前瞻性研究有假牙和无假牙情况下的牙齿状况如何成为总体死亡风险的预测指标。
对日本冲绳县宫古岛40岁以上的5688名社区居民进行了1987年至2002年为期15年的随访。
我们发现，功能性牙齿少于10颗且无假牙的女性受试者死亡率显著高于有假牙的女性受试者。男性受试者的死亡率无显著差异。功能性牙齿有10颗或更多颗的受试者，有假牙和无假牙者的死亡率无显著差异。
本研究表明，假牙是与死亡率相关的因素之一，尤其是在功能性牙齿少于10颗的女性受试者中。
