OBJECTIVES
The dental health of 73 workers previously exposed to mercury vapour at a chloralkali plant was studied and compared with that of 51 non-exposed referents.
METHODS
A record of oral, periodontal, gingival and mucosal conditions, including teeth, restorations, prostheses, and oral hygiene, was established during a 30 min examination. The participants' periodontal conditions were assessed according to the community periodontal index of treatment needs (CPITN). The results with the CPITN index were also compared with previously published data for another similar population.
RESULTS
There was no significant difference between the exposed workers and the referents with respect to the number of remaining teeth, amount of amalgam restorations, crowns, bridges, or endodontically treated teeth. The oral hygiene among the exposed workers was significantly better than among the referents, but the periodontal health conditions did not significantly differ between the two groups, nor from those of another Norwegian population.
DISCUSSION
The present results seem to contradict previous reports claiming tooth loss as a possible result of exposure to mercury vapour.
目的
对一家氯碱厂73名曾接触汞蒸气的工人的牙齿健康状况进行研究，并与51名未接触者进行对照比较。
方法
在30分钟的检查过程中，对口腔、牙周、牙龈和黏膜状况进行记录，包括牙齿、修复体、假牙及口腔卫生情况。根据社区牙周治疗需求指数（CPITN）评估参与者的牙周状况。还将CPITN指数的结果与先前发表的另一类似人群的数据进行比较。
结果
在留存牙齿数量、汞合金修复体数量、牙冠、牙桥或接受牙髓治疗的牙齿数量方面，接触汞蒸气的工人与未接触者之间无显著差异。接触汞蒸气的工人的口腔卫生状况明显优于未接触者，但两组之间的牙周健康状况无显著差异，且与另一挪威人群的牙周健康状况也无显著差异。
讨论
目前的结果似乎与先前声称接触汞蒸气可能导致牙齿脱落的报告相矛盾。
