About this study

We aim to examine 4 different methods to reduce dental aerosol spread during orthodontic procedures. These methods are: 1) high-volume evacuator, 2) high-volume evacuator and saliva ejector 3) Local Exhaust System 4) disinfection with povidone-iodine nasal swabs and chlorhexidine mouthwash.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Orthodontic debonding being performed
  • Acceptance to participate in the study and provide required saliva and nasal samples

Exclusion criteria

  • Refusal to participate
  • Refusal to provide saliva/nasal swab samples
  • Allergy to Chlorhexidine gluconate
  • Allergy to Povidone-Iodine

Treatment and study plan

Chlorhexidine mouthwash and Povidone-Iodine

Other

Chlorhexidine mouth rinse which participants use for 20 seconds before procedure. Moreover, Povidone-Iodine nasal swabs are used to disinfect nostrils

High volume evacuator

Device

High volume evacuator held by assistant to capture dental spray

High volume evactuator and saliva ejector

Device

High volume evacuator and saliva ejector held by assistant to capture dental spray

Local Exhaust System

Device

Local exhaust system hovers above patient head to capture dental spray

Primary outcomes

  1. Particle concentration measurements across the 4 different types of interventions

    Time frame: During procedure

  2. Mass concentration measurements across the 4 different types of interventions

    Time frame: During procedure

  3. Bioaerosol measurement from the tracked sources

    Time frame: During procedure

    Sources include patient, operator and assistant saliva and nasal secretions, preprocedural ambient air, dental unit waterline

Secondary outcomes

  1. Bacterial contamination on the inside surface of the mask of operators and assistants

    Time frame: During procedure

    Sources include patient, operator and assistant saliva and nasal secretions, preprocedural ambient air, dental unit waterline
