Abstract：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.
