酸作业工人牙酸蚀病的临床研究

The clinical research of the tooth acid erosion disease in workers related to acid jobs

作者通过对１４个工厂６种酸作业的１６７１名工人进行牙酸蚀病的调查，另设５０１名非接触酸作业的工人作为对照组进行对比分析。结果显示：职业性牙酸蚀病的发病率及病损程度与接触酸种类、酸作业工龄等有密切关系，以接触硫酸、硝酸工人发病率较高，分别为４１．１％和３８．９％，接触铬酸和磷酸工人发病率最低。

Abstract Through investigation into 1671 workers who do six acid related jobs in fourteen factories, and 501 workers who work in non-acid condition in contrast.The paper has worked out the criteria of diagnosing occupational acid erosion disease,including the classified criteria of diagnosing single tooth acid erosion disease and the criteria of diagnosing different degrees of the tooth acid erosion disease in the oral cavity. It has also been found out that these are close relationships between the rate of suffering the occupational tooth acid erosion disease and the degree of the erosion, on the one hand and density of acid fog in the air and the types of acid workers are exposed to and the lenth of the years working in such environment.
