在这项研究中，根龋的患病率在日本老年人的样本进行了调查沿着与各种病因学因素。287名60岁以上独立生活的老年人进行了检查，以了解活动性、非活动性和填充性牙根病变的患病率以及牙齿数量。调查受试者的一般健康状况、口腔状况和刷牙习惯，并根据唾液流量和进食时口干的主观感觉确定唾液流量。约39%的受试者有一个或一个以上的根龋，53.3%的受试者至少有一个根龋或根充。根龋最常见的犬齿其次是第一前磨牙。随着残牙数的增加，龋坏或充填的病变数量增加（Kruskal-Wallis检验，P = 0.033），但是，牙根龋坏的牙齿比例与牙齿数量之间没有关联。对于有20颗或更多牙齿的受试者，经常刷牙的受试者的牙根龋坏数量可能较低（P = 0.058），唾液流量低（P = 0.059）或主观感觉口干（P = 0.052）的受试者的牙根龋坏数量可能较高（卡方）。龋齿的存在可能与口干（P = 0.057，比值比3.13）和刷牙频率（P = 0.088，比值比1.76）相关（多元logistic回归分析）。结果表明，高频率的根面龋在这个日本社区居住的老年人口。口腔卫生状况和低唾液流量或感觉口干是疾病的潜在危险因素。
In this study, the prevalence of root caries in a sample of Japanese elders was investigated along with various aetiological factors. Two hundred and eighty-seven independently living elderly people over the age of 60 years were examined for the prevalence of active, inactive, and filled root lesions as well as the number of teeth. General health, oral status and brushing habits were surveyed, and salivary flow was determined in terms of flow rate and subjective feeling of dry mouth during eating. About 39% of the subjects had one or more decayed roots and 53.3% had at least one decayed or filled lesion. Root caries was seen most frequently on canine teeth followed by the first premolar. The number of decayed or filled lesions increased with increasing number of residual teeth (Kruskal-Wallis test, P = 0.033), however, there was no association between the proportion of teeth with root decay and the number of teeth. For subjects with 20 or more teeth, the number of decayed roots is likely to be lower in subjects who reported brushing frequently (P = 0.058), and higher in subjects with low salivary flow (P = 0.059) or subjective feeling of dry mouth (P = 0.052) (Chi-squared). The presence of decayed lesions is likely to be related to dry mouth (P = 0.057, odds ratio 3.13) and brushing frequency (P = 0.088, odds ratio 1.76) (Multiple logistic regression analysis). The results indicate a high frequency of root surface caries in this Japanese community-dwelling older population. Oral hygiene status and low salivary flow or perceived dry mouth were potential risk factors for disease.
