Abstract : In dental treatment, tooth particles, microbes, saliva and blood expelled during tooth cutting procedures can cause the hazards of infection to patients and to members of the medical staff. An extraoral dental suction system is often used as a method of eliminating sources of infection during tooth cutting.
In order to investigate the effectiveness of the extraoral dental suction system in reducing the risk of infection, we implemented the system during treatment in a clean booth ; i. e. we treated some patients requiring tooth cutting with the extraoral dental suction system, thus employing the microbe and ground particles removing capabilities in the patient’s oral cavity ; Bacillus sibtilis spores were sprayed experimentally with an atomizer in the same clean booth.
Excellent particle and microbe removing capabilities were observed in the experiment, thus verifying the effectiveness of the system to reduce the hazards of infection.
