The purpose of the study was to evaluate the oral health situation of workers in the Danish granite industry, in particular, to describe the prevalence and severity of dental abrasion. Measurements of the work environment showed that the workers were exposed to abrasive quartz dust. A total of 39 workers (72%) completed a questionnaire on their dental health, work environment, and symptoms from the masticatory system. Only 10% had been treated by school dental services, and only 51% made regular visits to the dentist. Consequently, the clinical examinations revealed a high prevalence of dental caries (mean number of decayed, missing, and filled surfaces 87.2). The workers' periodontal conditions were poor; the mean percentage of teeth with gingivitis, calculus and pockets deeper than 5 mm was 13.4. The prevalence of dental abrasion was 100%; in particular, abrasion was observed on the front teeth. The severity of abrasion and the affection ratio increased by duration of exposure to dust. In conclusion, dental abrasion induced by work-related dust should be considered an occupational disease.
该研究的目的是评估丹麦花岗岩行业工人的口腔健康状况，特别是描述牙齿磨损的患病率和严重程度。工作环境测量表明，工人接触到有磨蚀性的石英粉尘。共有39名工人（72%）完成了一份关于他们牙齿健康、工作环境和咀嚼系统症状的问卷。只有10%的人接受过学校牙科服务治疗，只有51%的人定期看牙医。因此，临床检查显示龋齿患病率很高（龋、失、补牙面平均数为87.2）。工人的牙周状况很差；患牙龈炎、牙结石和牙周袋深度超过5毫米的牙齿平均百分比为13.4。牙齿磨损的患病率为100%；特别是在前牙上观察到磨损。磨损的严重程度和患病比例随接触粉尘的时间而增加。总之，与工作相关的粉尘引起的牙齿磨损应被视为一种职业病。
