Since the orthodontic pliers are easily corroded by high vacuum steam sterilization such as the autoclave, these are sterilized using ethylene oxide gas (EOG) after the lubrication. It is well known that ethylene oxide and its by-products were detected from plastics, water and so on as noxious residues even after the air ventilation following EOG sterilization. If these noxious residues were detected in the lubricants from the orthodontic pliers, the patients might be influenced through their toxicity. In the present study, we examined whether the ethylene oxide and its by-products were detected from the orthodontic pliers after EOG sterilization. In a quantitative analysis using the gas chromatography, ethylene oxide still remained on the orthodontic pliers with relatively high concentration. In the proton-nuclear magnetic resonance analysis and the mass spectrograph analysis, the noxious by-products that were made from ethylene oxide were not detected on the orthodontic pliers.
