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.
Interventions
OTHERChlorhexidine 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
DEVICEHigh volume evacuator
High volume evacuator held by assistant to capture dental spray
DEVICEHigh volume evactuator and saliva ejector
High volume evacuator and saliva ejector held by assistant to capture dental spray
DEVICELocal Exhaust System
Local exhaust system hovers above patient head to capture dental spray
