With the anticipated increase in the aged adult population and the associated gingival recession, the prevalence of root caries is expected to increase. The purpose of this study was to determine the experience and distribution of root caries in a group of aged adults living in Kayelitsha. All non-institutionalized elderly black adults participating in a community geriatric programme were examined. Root caries was recorded using visual and tactile criteria and expressed as the root caries index (RCI) rate. The mean age of the subjects was 65.2 years, the mean number of teeth present was 17.3 and the mean RCI rate was 2.2 per cent. All subjects had gingival recession while only 23.8 per cent had root caries. No surfaces with restored root caries lesions were found. In the maxilla the highest RCI rate was observed on the interproximal surfaces of the posterior teeth (4.4 per cent) but in the mandible the buccal surfaces of the posterior teeth had the highest RCI rate (4.2 per cent). In both the maxilla and the mandible the lingual surfaces of the anterior teeth showed no root caries. Maxillary teeth did not have a significantly higher root caries attack rate than mandibular teeth. Root caries does not appear to be a public health problem in the sampled population.
随着老年人口的预期增加以及相关的牙龈退缩，根龋的患病率预计将会上升。本研究的目的是确定居住在凯伊利沙的一组老年人中根龋的患病情况和分布。对所有参与社区老年项目的非机构化老年黑人成年人进行了检查。根龋通过视觉和触觉标准进行记录，并以根龋指数（RCI）率表示。受试者的平均年龄为65.2岁，平均牙数为17.3颗，平均RCI率为2.2%。所有受试者均有牙龈退缩，而仅有23.8%的人患有根龋。未发现有根龋病变修复的牙面。在上颌，后牙邻面的RCI率最高（4.4%），但在下颌，后牙颊面的RCI率最高（4.2%）。在上颌和下颌，前牙舌面均未出现根龋。上颌牙的根龋发病率并不显著高于下颌牙。在抽样人群中，根龋似乎不是一个公共卫生问题。
