目的：通过对义齿制作中心一些常用操作项目所产生的噪声、粉尘达标情况进行检测，为规范义齿制作中心管理和技师职业病防控提供理论依据。方法分别对打磨金属、塑料、瓷体产生的噪声、粉尘进行监测，与国家卫生标准对照分析。结果打磨金属、塑料、瓷体产生的噪声，测定值呈渐进性增高，个别为高频，超标率达63.3%。打磨金属、塑料产生粉尘时间加权平均容许浓度平均值（PC-TWA）分别是10.75 mg/m3、9.07 mg/m3，超标率达100%；打磨瓷体的 PC-TWA 为8.84 mg/m3，超标率为40%。结论义齿制作中心噪声和粉尘污染问题需引起重视，应采取有效的防尘降噪措施和个人防护措施，从而保障技师的健康。

In order to provide theoretical evidence about management of denture production as well as prevention of technicians’ occupational disease, daily operations in denture producing center are detected which consist of noise and dust situation, etc. The noise and dust which were from polished mental, plastic and porcelain were respectively detected. In the meantime, the result was compared with national hygiene standard. The result of the noise from polished mental, plastic and porcelain is gradually going up, while some data reach to high point, over standard rate is 63.3%. Precisely, the PC-TWA(permissible concentration-time weighted average) of dust from polished mental and plastic are 10.75 mg/m3、and 9.07 mg/m3 respectively. In other words, the result is completely over the standard level. Meanwhile, the PC-TWA of polished porcelain is 8.84 mg/m3,which is over standard around 40% . Noise pollution and air pollution in denture producing center should be paid high attention. In order to guarantee the health issues of technicians, effective measurements should be proceeded, consisting of pollution prevention and personal protection of staff.
