摘要： 目的分析与评价口腔修复诊室中粉尘污染问题并提出合理的防护建议。方法使用扫描电镜（scanning electron microscope,SEM）、X射线能谱色散谱仪（energy dispersive spectrometer,EDS）及粉尘浓度激光测试仪作为检测手段,对口腔修复中常用的5种义齿材料（饰面瓷、钴铬合金、光敏塑料、超硬基托树脂、高级人工牙）所产生的粉尘进行颗粒的粒径大小、元素组成及粉尘浓度分析,评估口腔修复诊室粉尘对医务人员健康的影响,并提出口腔诊室粉尘防治的合理化建议。结果饰面瓷、钴铬合金、光敏塑料、超硬基托树脂、高级人工牙的粉尘颗粒粒度分别为（2.15±3.00）、（33.78±24.33）、（7.78±11.86）、（31.16±44.35）及（28.45±39.21）μm。其中,饰面瓷呼吸性粉尘的时间加权平均容许浓度为0.393 mg/m2,超出国家安全范围。结论口腔修复诊室中粉尘污染严重,应予以重视,并采取适当的防护措施。

Abstract: PURPOSE: To analyze and evaluate dust pollution in prosthodontic clinic and make proposal for reasonable protection. METHODS: This study analyzed the particle size, element composition and dust concentration of 5 materials which were commonly used in dental restorations (veneering ceramics, cobalt-chromium alloy, photosensitive plastic, hard base resin, advanced artificial teeth) by using scanning electron microscopy (SEM), X-ray energy dispersive spectrometer（EDS） and dust concentration laser tester, in order to assess the effects of prosthodontic dust posed on medical staff health and put forward reasonable suggestions for prevention and control of dust pollution. RESULTS: The particle size of veneering ceramics, cobalt-chromium alloy, photosensitive plastic, hard base resin and advanced artificial teeth was (2.15±3.00), (33.78±24.33), (7.78±11.86), (31.16±44.35) and (28.45±39.21)μm, respectively. The time weighted average respirable dust concentration of veneering ceramics was 0.393 mg/m2 which was beyond the scope of national security. CONCLUSIONS: Dust pollution is serious in prosthodontic clinic to which we should pay more attention and take appropriate prevention measures.
