| Research Abstract |
Without performing tooth preparation, the "Clean-Area-System" makes a pillar of clean air up to the 0.3mum particle dusts class 10,000/CF and around the patient's face fixed measured territory (30cm*30cm*150cm) that showed to have more clean area than 0.3mum particle dusts class 10,000/CF during dental procedures.
The "Clean-Area-System" proved to be effective to reduced the airborne infection dusts in the operation area during the work static procedures such as hand scaling, endodontics treatment.
But during tooth preparation procedures using only the "Clean-Area-System", the degree of purity of airborne infection dusts was more than 0.3mum particle downward class 10,000/CF.
So, it was necessary to set both the "Intra and Extra-Oral-Vacumm-Aspirator" and the "Clean-Area-System" during tooth preparation procedures.
The "Clean-Area-System" is an effective device for a protective operation area.
Also we could find oral-alpha-haemolytic streptococci only in the airborne bacterium present in the dental clinic but could not find it in the dental clinic's waiting room and in the research room.
It was proved that oral-alpha-haemolytic streptococci was useful as an indicator for splashing infection control in the present study.
