Study Details

Study Description

Brief Summary

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

Condition or Disease	Intervention/Treatment	Phase
Risk Reduction Occupational Exposure Dentist-Patient Transmission	Other: Chlorhexidine mouthwash and Povidone-Iodine Device: High volume evacuator Device: High volume evactuator and saliva ejector Device: Local Exhaust System	N/A

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

Anticipated Enrollment :

40 participants

Allocation:

N/A

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Orthodontic debonding	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
