The German Association for Dentistry project "Epidemiology" studied the dental findings of 2,336 patients over the age of 15 in 15 dental practices in Middle Hesse. Occupation-related evaluation of the DMF-T index and the oral hygiene findings showed that the caries rate was relatively unrelated to the patient's occupation. Differences in the state of oral hygiene however were observed.
德国牙科协会的“流行病学”项目对黑森州中部15家牙科诊所的2336名15岁以上患者的牙齿检查结果进行了研究。对DMF-T指数和口腔卫生检查结果进行的职业相关性评估显示，龋齿率与患者职业的相关性相对较低。然而，观察到了口腔卫生状况的差异。
