In this longitudinal study of a random sample of North Carolinians over the age of 65 and living in their homes, 325 blacks and 280 whites were examined and interviewed 18 months after baseline examinations. Coronal caries incidence was greater among whites than blacks. The increment due to teeth becoming root fragments were similar for both races; however, there were more newly crowned teeth among whites. Newly crowned surfaces were not used as part of the caries increment in logistic regression models to investigate potential risk predictors. For blacks, caries development over the 18-month period was associated with a higher lactobacillus score and more coronal caries at baseline, more previously filled coronal surfaces, and lack of active membership in clubs or other groups. For whites, having no self-reported tooth sensitivity, having a lower socioeconomic index score, taking antihistamine medications at baseline, and having the perception of more problems after the age of 40 than before were all associated with the development of coronal caries.
在这项针对年龄在65岁以上且居住在家中的北卡罗来纳州人的随机抽样纵向研究中，在基线检查18个月后，对325名黑人及280名白人进行了检查和访谈。白人的冠龋发病率高于黑人。牙齿变为牙根碎片导致的龋病增加在两个种族中相似；然而，白人中新镶牙更多。在用于研究潜在风险预测因素的逻辑回归模型中，新镶牙面未被用作龋病增加的一部分。对于黑人，18个月期间的龋病发展与较高的乳酸杆菌评分、基线时更多的冠龋、更多先前已充填的冠面以及未积极加入俱乐部或其他团体有关。对于白人，自我报告无牙齿敏感、社会经济指数得分较低、基线时服用抗组胺药物以及认为40岁以后比以前有更多问题均与冠龋的发展有关。
