Summary

The study examines 4 different methods to reduce dental bioaerosol spread in orthodontic procedures.

Detailed description

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.

Conditions

• Risk Reduction
• Occupational Exposure
• Dentist-Patient Transmission

Interventions

Type	Name	Description
OTHER	Chlorhexidine mouthwash and Povidone-Iodine	Chlorhexidine mouth rinse which participants use for 20 seconds before procedure. Moreover, Povidone-Iodine nasal swabs are used to disinfect nostrils
DEVICE	High volume evacuator	High volume evacuator held by assistant to capture dental spray
DEVICE	High volume evactuator and saliva ejector	High volume evacuator and saliva ejector held by assistant to capture dental spray
DEVICE	Local Exhaust System	Local exhaust system hovers above patient head to capture dental spray
