Abstract Objective: To compare the three kinds of disinfectant for non-plug type Put tooth sandblasting machine handle disinfection. Methods: 75% alcohol, 0.25% glutaraldehyde, 2000mg / L chlorine preparations for non-plug-blasting machine handle Put teeth before and after disinfection were sampled for bacterial culture, observe disinfection. Results: Using three kinds of disinfectant wipe three minutes, are able to kill the sandblasting machine handle type Put tooth surface bacteria, but 0.25% glutaraldehyde, 2000mg / L chlorine sterilization effect is excellent preparation Ding 75,010 alcohol. Conclusion: 0.25% glutaraldehyde, 2000mg / L chlorine preparations wipe sandblasting machine handle type Put tooth surface disinfection effect is reliable.

 

Put teeth Keywords sandblasting machine handle pollution measures

    With the development of oral medicine, blasting Put governance has been recognized. Put teeth while sandblasting machine handle dental treatment units with high-speed mobile phone as easily be oral saliva, blood and plaque pollution can cause iatrogenic cross-infection. So we put on non-plug-blasting machine handle tooth investigate pollution status, and three kinds of disinfectants disinfection efficacy evaluation.

 

Materials and Methods

 

    Material: Put teeth sandblasting machine Sately), sterile swabs, 0.25% glutaraldehyde, 75% alcohol, 2000mg, L

 

Warm Seoul preparation facilities available chlorine disinfection tablets and paper).

 

    Methods: February 2008 - February 2009 from my hospital outpatient oral medicine used randomly selected 60 patients Put teeth after sandblasting machine handle sampled. 20 samples of each disinfectant. Before sampling requires nurses hand disinfectants, masks, hats. Both before disinfection wipe with a sterile cotton swab back and forth five times the entire surface of the handle, the fire tube mouth disinfection, hand contact with a cotton swab to remove part of the sample in saline beat 80 times to make agar pour lotion Iml inoculated at 37 ℃ incubator for 24 hours observation. After the initial sampling, dip a cotton swab saturated with sterile disinfectant wipe 3 minutes, for the first two samples.

 

    Statistical analysis: Statistical analysis SPSS13.0 statistical software, using the X2 test and rank sum test.

 

Result

 

    Three kinds of disinfectant before and after bacterial detection rate: 0.25% glutaraldehyde and 2000mg / L chlorine disinfection agents in detection of bacteria after 5%; 75% alcohol disinfection of bacteria detected in the case of 10%; 0.25% amyl dialdehyde, 2000mg / L chlorine disinfection agents in detection of bacteria between with 75% alcohol, the difference was statistically significant. Table l.

 

    Three kinds of disinfectant effect of contrast: Put teeth from sandblasting machine handle the total number of bacteria compared before and after disinfection, 0.25 01. Glutaraldehyde; 75,010 alcohol; 2000mg / L chlorine preparations were able to achieve the purpose of disinfection, but 0.25% glutaraldehyde and 2000mg / L chlorine preparations to be gifted Ding 75% alcohol wipe disinfection. Table 2.

 

For discussing

 

    Put governance blasting machine is a comprehensive treatment of the platform by connecting the output of the system is powered water vapor, using a dedicated dentifrice sandblasting sandblasting put in the role of high-speed impact pressure tooth surface, so as to achieve the purpose of cleaning and polishing. Put the work in the oral cavity dental sandblasting machine handle does not contact the tooth surface, the saliva in the oral cavity of patients, ultrasound generated during cure put blood and plaque, in the impact of air contamination in dental sandblasting machine handle Put. In this experiment, after the blasting treatment, the handle contamination rate 58.3%, the average amount of bacteria is also up to 659cfu / piece. Put teeth shows sandblasting machine handle pollution is very serious, such as disinfection measures are not taken, can easily cause iatrogenic cross-infection. Currently, dental sandblasting machine Put autoclavable handle with the most effective, it will be under 135 ℃, the role of six minutes, eight minutes later, the instrument is attached to the army to kill 100% of bacteria, chemical indicator card full color, bio-indicator bacteria slice cultures were all negative. Put as many dental sandblasting machine handle non-plug-in can not be

 

Autoclave, only use disinfectant wipe method.

 

    Often used in clinical disinfectant more types. In this study, 75% alcohol, chlorine preparations, 0.25 01. Glutaraldehyde three kinds of disinfectant. From the experimental results, chlorine disinfection agents and glutaraldehyde better, 75,010 times. Although China has been reported 2% iodine +75% alcohol to eliminate hepatitis B virus, but it has some 75,010 alcohol-volatile disinfection effect is not ideal, is not recommended. Glutaraldehyde disinfectant solution is alkaline, with a strong microbicidal ashamed to use. Liu Liping rings and other reports, 2010 30 minutes glutaraldehyde disinfectant can kill HBSAg completely at room temperature for dental instruments corrosive and water to the same extent, the basic non-corrosive, stable physical and chemical properties. However, due 2010 glutaraldehyde on the skin and mucous membrane irritation, the present study, 0.25% glutaraldehyde disinfection effect is ideal. In this study, the use of chlorine preparations for the Shanghai production facilities available Ireland broad-spectrum fungicide disinfectant tablets, chlorine 2000mg / L solution, 2 minutes completely kill E. coli and Staphylococcus aureus; 15 minutes to completely destroy HB-SAg. Wipe the surface sandblasting scaler handle 3 minutes bacterial clearance rate was 96.3 010.

 

    Oral care work tedious, heavy task. For comprehensive treatment of Taiwan's high-speed handpiece, scaler should adopt the "one person, one machine a sterile", for not using the autoclave method should be used to wipe disinfection equipment to reduce cross-contamination. Use disinfectant method, due to the use of disinfectants large have odor, skin, mucous membrane irritation. Therefore, the operation is necessary to wear masks, gloves, prevent accidents and allergies. In addition, the sandblasting scaler handle sterilized aseptic bags put on the application, to avoid re-contamination, if not used within 24 hours, and then use the next time you use should be preceded by disinfection.
