In the last decade the effect of oral health on the general health and mortality of elderly people has attracted attention. We explored the association of dental health behaviors and dentition on all-cause mortality in 5611 older adults followed from 1992 to 2009 (median = 9 years) and calculated risk estimates using Cox regression analysis in men and women separately. Toothbrushing at night before bed, using dental floss everyday, and visiting the dentist were significant risk factors for longevity. Never brushing at night increased risk 20-35% compared with brushing everyday. Never flossing increased risk 30% compared with flossing everyday. Not seeing a dentist within the last 12 months increased risk 30-50% compared with seeing a dentist two or more times. Mortality also increased with increasing number of missing teeth. Edentulous individuals (even with dentures) had a 30% higher risk of death compared with those with 20+ teeth. Oral health behaviors help maintain natural, healthy and functional teeth but also appear to promote survival in older adults.
在过去十年中，口腔健康对老年人总体健康和死亡率的影响已引起关注。我们对1992年至2009年随访的5611名老年人（中位数=9年）的牙齿健康行为和牙列与全因死亡率之间的关联进行了探究，并分别使用Cox回归分析对男性和女性计算风险估计值。睡前刷牙、每天使用牙线以及看牙医是长寿的重要危险因素。与每天刷牙相比，从不晚上刷牙会使风险增加20%-35%。与每天使用牙线相比，从不使用牙线会使风险增加30%。与每年看牙医两次或更多次相比，过去12个月内未看牙医会使风险增加30%-50%。死亡率也随着缺牙数量的增加而上升。无牙个体（即使佩戴假牙）与牙齿数量在20颗及以上的个体相比，死亡风险高出30%。口腔健康行为有助于保持天然、健康和功能正常的牙齿，而且似乎还能提高老年人的生存率。
