Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

NONE

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Orthodontic debonding

Group Type EXPERIMENTAL

Chlorhexidine mouthwash and Povidone-Iodine

Intervention Type OTHER

Chlorhexidine mouth rinse which participants use for 20 seconds before procedure. Moreover, Povidone-Iodine nasal swabs are used to disinfect nostrils

High volume evacuator

Intervention Type DEVICE

High volume evacuator held by assistant to capture dental spray

High volume evactuator and saliva ejector

Intervention Type DEVICE

High volume evacuator and saliva ejector held by assistant to capture dental spray

Local Exhaust System

Intervention Type DEVICE

Local exhaust system hovers above patient head to capture dental spray
