BACKGROUND
Dental practice is subjected to biologic risk on a daily basis, a risk that could affect both operators and patients. The aim of this study was to observe that the use of protective devices and medical devices allows to limit and eliminate this risk, especially in the case of cross infections.
METHODS
The methods of disinfection of surfaces and instruments are different and could include both physical and chemical methods. In this in-vitro study the effectiveness of sterilization of microwave methods was assessed. In this study microwave sterilization with a 1800W protocol for 5 minutes has been performed.
RESULTS
Once the bacterial contamination of some dental instruments was carried out, and left the latter in culture medium, the disinfection phase was carried out, by inserting the instruments in a microwave chamber. These new sterilization protocols allow to obtain surfaces or instruments sterilization in a short time.
CONCLUSIONS
Even though it cannot be used with all materials, the use of this method has excellent properties for the sterilization of dental medical instruments, even if with lower performance than the conventional autoclave.
背景
牙科实践每天都面临着生物风险，这种风险可能会影响到操作人员和患者。本研究的目的是观察使用防护设备和医疗器械可以限制和消除这种风险，特别是在交叉感染的情况下。
方法
表面和器械的消毒方法不同，可能包括物理和化学方法。在这项体外研究中，评估了微波方法消毒的效果。在这项研究中，采用 1800W 方案进行了 5 分钟的微波消毒。
结果
在对一些牙科器械进行细菌污染检测后，将这些器械留在培养基中，然后进行消毒阶段，将器械插入微波室。这些新的消毒方案允许在短时间内对表面或器械进行消毒。
结论
尽管不能用于所有材料，但这种方法具有极好的牙科医疗器械消毒性能，即使性能低于传统的高压灭菌器。
