Study Overview
Brief 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.
Study Design
- Study Type
- Interventional
- Allocation
- Na
- Intervention Model
- Single Group
- Primary Purpose
- Prevention
- Masking
- None
Masking Description
Each participant and operator know the model which was assigned to them. The research assistant conducting the analysis is not able to identify the samples until analysis time.
