The prevalence and pattern of distribution of root caries were determined in a Scottish Medieval population. The principal finding was a lower root caries prevalence, compared with that of modern times, with respect to surfaces at risk; this was particularly marked with respect to buccal root caries. A lower intake of refined sugars and the presence of heavy deposits of supragingival calculus are suggested as factors that may be responsible for the observed differences. The common site for the early root caries lesion was just apical to the enamel-cementum junction. Initially, it extended laterally in the form of an elliptical erosion; however, the greater the depth of the lesion, the more circular the outline became.
对苏格兰中世纪人群的根龋患病率及分布模式进行了测定。主要发现是，与现代相比，有患龋风险的牙面根龋患病率较低；这在颊侧根龋方面尤为明显。精制糖摄入量较低以及龈上牙石大量沉积被认为可能是导致观察到的差异的因素。早期根龋损害的常见部位恰好在釉质-牙骨质界的根尖方。最初，它以椭圆形侵蚀的形式向侧面扩展；然而，损害越深，轮廓越呈圆形。
