近年来,医院口腔科大量应用汞合金作龋齿填充材料,为了摸清汞对口腔科医务人员健康的影响,我们对六个铁路医院口腔科的作业环境条件、医务人员的健康状况进行了调查,其结果报告如下: 一、环境条件 (1)一般情况:调查的六个医院口腔科大小不一,小者只设有两个治疗台,大者设有十二个治疗台。治疗室内一般都比较拥挤,没有机械通风设备。六个医院口腔科门诊量都比较大,少者每日门诊号40,多者每日门诊号200。龋齿填充病例占每日总门诊号40～50％(儿童少年最多),因而各医院每日用汞量0.5～1.5公斤。龋齿填充时没有固定人员调和汞合金,每个医务人员随治随调。调和时将8份金属汞与5份银粉合在一起,放在乳钵内研磨后,倒在手掌上挤压,把多余的汞抛弃。
In recent years, a large number of hospital dental applications of amalgam for dental caries filling materials, in order to find out the health effects of mercury on the dental health care workers, The results are reported as follows: First, the environmental conditions (1) General situation: The survey of the six hospitals of different sizes, the smaller person only has two treatment stations, the larger with twelve treatment stations. Treatment rooms are generally more crowded, there is no mechanical ventilation. The number of outpatient clinics in the six hospitals is relatively large, with less than 40 daily outpatients and more than 200 daily outpatients. Dental caries filling cases account for 40-50% of daily total outpatient visits (with the largest number of children and adolescents), so hospitals use daily amounts of 0.5-1.5 kg of mercury. Caries filled with no fixed personnel to reconcile amalgam, with each medical personnel attendant. When reconcile the 8 parts of metal mercury and 5 parts of silver together, placed in the mortar grinding, pour on the palm squeeze, the excess mercury abandoned.
