Study Summary
The purpose of this study is to evaluate the effectiveness of external evacuation units and mouth rinses during aerosol generating procedures in a dental clinic and to determine the risk level to the dental practitioners during aerosol generating procedures.
Primary Outcome
At baseline (1 hour before treatment), four agar petri dishes will be placed at standardized distances (2 ft, 3 ft, 4 ft, and 6 ft) from the dental chair headrest in the operating room. An impinger will also be positioned 2 ft from the headrest. The number of bacterial colony-forming units (CFUs) will be counted for each petri dish and the impinger after a 72-hour incubation period. The average number of Bacterial CFUs is reported.
Interventions
- DRUG Placebo
- DRUG Hydrogen Peroxide
- DEVICE High volume evacuation (HVE)
- DEVICE Extraoral vacuum aspirator (EVA)
