Failure of non-vacuum steam sterilization processes for dental handpieces

Effectiveness of Bench Top Non-Vacuum Autoclaves on Dental Turbine Chamber Sterilization

Introduction: Dental turbine chamber is a suitable reservoir for living microorganisms, so chamber sterilization is necessary for reducing cross contamination risk. On the other hand, in non-vacuum autoclaves, steam penetration into turbine chamber is doubtful, while they are still in use in dental clinics. In this study, performance of small non-vacuum autoclave in turbine chamber sterilizatio...

Monitoring sterilization of dressings in high-vacuum pressure-steam sterilizers.

Undetected air leaks in a high-vacuum sterilizer can defeat the sterilization process. For this reason the maintenance and supervision of these sterilizers needs expert engineering care. The importance of controlling the high-vacuum sterilization process from the centre of a load rather than the chamber drain is emphasized, and a method of detecting any failure in a high-vacuum process is descr...

Performance of high-speed dental handpieces subjected to simulated clinical use and sterilization.

BACKGROUND The authors investigated the performance of nine commercially available high-speed air-turbine dental handpieces subjected to 1,000 simulated clinical uses and sterilizations. METHODS Six new handpieces from each of nine different models were subjected to simulated clinical use with a custom-made handpiece wear tester and then autoclaved. Ten parameters related to clinical performa...
