Trial Outcomes & Findings for Evaluation of Aerosol in a Dental Clinic (NCT NCT04659928)
NCT ID: NCT04659928
Last Updated: 2025-07-08
Results Overview
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.

High Volume Evacuation (HVE) Suction Only and Hydrogen Peroxide
High volume evacuation (HVE): Intra oral suction will be done and during the procedure,bacterial colony forming units (cfus) will be captured during dental care by placing large format petri dishes containing bacterial culture media in the dental operatory with open lids. Once aerosol capture is complete, petri dishes will be incubated and quantified under BSL-2 safety conditions in the lab. Patient will be given a mouth rinse.
Hydrogen Peroxide: Subjects will be given 1.5 % Oral Solution of hydrogen peroxide mouth rinse
