Objective　　　To evaluate the disinfection effect of ZJX-1 oral lightwave sterilizer.　　　 Methods　　　The laboratory disinfection effect of ZJX-1 oral lightwave sterilizer was observed by carrier quantitative germicidal experiment and physicochemical measurement.　　　 Results　　　Escherichia coli

Pseudomonas aeruginosa

Staphylococcus aureus

HBV-DNA and Candida albicans were completely killed in 3 min with the sterilizer

and the disinfection passing rate reached 100%. Bacillus subtilis was killed in 5 min

and the disinfection passing rate also reached 100%. The UV intensity was 885 μW/cm

2

-2 000 W/cm

and temperature was 137-161 ℃ in the sterilizer in 1 to 5 min

consisting with the disinfection technology standards. In accordance with the normative standards

the corrosion rates (expressed in mm/year) of stainless steel

copper

carbon steel and aluminum were 0.000 0

0.113 3

0.294 5 and 0.055 2 respectively when the sterilizer run for 75 h.　　　 Conclusion　　　This new ZJX-1 oral lightwave sterilizer can achieve the same disinfection effect with high temperature autoclave and high pressure steam sterilization. It is an economical

convenient and practical dentistry disinfection equipment.
