This study investigated tooth loss in North Carolina adults 65 years of age or older. A random sample of 335 Blacks and 284 Whites participated in dental examinations and interviews at baseline and again after 18 months. Blacks were more likely than Whites to lose at least one tooth (36% vs 19%), and they lost more teeth on average (1.0 vs 0.4). Several oral disease conditions and symptoms were related to tooth loss, but many other hypothesized factors were not. Risk models were inconclusive in the identification of factors related to risk of tooth loss.
本研究调查了北卡罗来纳州65岁及以上成年人的牙齿脱落情况。335名黑人和284名白人的随机样本在基线时参加了牙科检查和访谈，并在18个月后再次接受检查和访谈。黑人比白人更有可能至少掉一颗牙（36%对19%），而且他们平均掉牙更多（1.0颗对0.4颗）。几种口腔疾病状况和症状与牙齿脱落有关，但许多其他假设因素并无关联。风险模型在识别与牙齿脱落风险相关的因素方面尚无定论。
