The relationship between caries on root surfaces and untreated coronal lesions was analyzed. A representative sample of 5028 persons was examined, their mean ages being 47.3 years for men and 47.7 for women. Poor dental health on root surfaces was associated with poor dental health in the coronal areas of the teeth. Subjects with root caries had fewer teeth and fewer fillings, more retained roots and more teeth with untreated coronal decay than did people with no root caries. Compared with the subjects without untreated coronal decay, those with from one to three decayed coronal surfaces showed an odds ratio of 4.5 of having caries on root surfaces. This ratio was 10.1 for the subjects who had more than three decayed coronal surfaces. It was concluded that factors related to the occurrence of decay are of a similar type whether caries is situated on root surfaces or in the coronal areas of the teeth, and therefore the prevention of caries in both sites may be accomplished by similar means.
分析了根面龋与未治疗的冠部病变之间的关系。对5028人的代表性样本进行了检查，男性的平均年龄为47.3岁，女性为47.7岁。根面牙齿健康状况不佳与牙齿冠部区域的牙齿健康状况不佳相关。与无根面龋的人相比，有根面龋的受试者牙齿数量更少、补牙更少、保留牙根更多，且有更多冠部未治疗龋坏的牙齿。与无冠部未治疗龋坏的受试者相比，有1至3个龋坏冠面的受试者发生根面龋的比值比为4.5。对于有超过3个龋坏冠面的受试者，该比值比为10.1。得出的结论是，无论龋病位于根面还是牙齿的冠部区域，与龋病发生相关的因素类型相似，因此通过类似的方法可以预防这两个部位的龋病。
