The oral health of 100 rural Black Xhosa men commencing employment on the gold mines was examined. Dental caries were present in 68%, the mean DMFT per mouth was 2.5 (s.d. 2.8) while the mean DMFT per carious mouth was 3.7 (s.d. 2.7). Oral hygiene was good and periodontal disease uncommon. Although the frequency of individuals with dental caries has increased since studies on similar groups were made 40 years ago, the severity of the disease in affected individuals has remained static.
对100名刚开始在金矿工作的农村科萨族黑人男性的口腔健康状况进行了检查。68%的人患有龋齿，每人口腔的平均龋失补牙数（DMFT）为2.5（标准差2.8），而每颗患龋牙齿的平均DMFT为3.7（标准差2.7）。口腔卫生状况良好，牙周疾病并不常见。尽管自40年前对类似群体进行研究以来，患龋齿个体的比例有所上升，但受影响个体的疾病严重程度一直保持稳定。
