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.
