Evaluation of Aerosol in a Dental Clinic

Purpose

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.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
High volume evacuation (HVE) suction only and hydrogen peroxide
  • Device: 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 hydrogen peroxide rinse.
  • Drug: Hydrogen Peroxide
    Subjects will be given 1.5 % Oral Solution of hydrogen peroxide mouth rinse
Experimental
HVE suction and extraoral vacuum aspirator (EVA) and hydrogen peroxide
  • Device: 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 hydrogen peroxide rinse.
  • Device: Extraoral vacuum aspirator (EVA)
    Extraoral suction connected to dental suction will be used and 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 hydrogen peroxide rinse.
  • Drug: Hydrogen Peroxide
    Subjects will be given 1.5 % Oral Solution of hydrogen peroxide mouth rinse
