Reducing Aerosol and Bioaerosol Using Different Oral Suctions

Summary

Aerosol particles generated when using dental instrument such as ultrasonic and high air driven handpieces, this aerosol is mixture of blood, saliva, infectious agents, and dental materials. Inhaler dust that range between PM2.5 to PM10 could transferred to the human lung's terminal bronchioles and alveoli that cause a harm effect. The aim of this study to assess the effectiveness of different dental suction devices that could be contributed to decrease risk of particles count, Bacterial and fungal that arising from patient mouth to indoor air dental clinic. This is a randomized clinical trial will be conducted in three different places: educational hospital, public hospital, and private clinic. In each place 40 subject will be recruited. Measurement including particles count and microorganism will be taken before 15 minutes and during of scaling and prophylaxis procedure to measure particles count, oral bacteria, fungus, and microbial air. In this study will be compared between four intervention groups; Group A with high and low suction only, Group B using dry shield suction and low section, Group C using extra-oral suction with high and low suction, and Group D using dry shield suction and extra-oral suction and low section. Difference between each categorical groups and particle, oral bacterial, fungus, and microbial air concentration will be tested using two-way ANOVA test or one way ANOVA test. Statistical analysis will be carried using STATA version 13.

Interventions

DEVICE

low suction

This group receives low-volume intraoral suction during procedures. Low suction typically refers to standard saliva ejectors, which provide minimal suction power and are commonly used in routine dental treatments.

DEVICE

intraoral suction

This group receives conventional intraoral suction, likely using high-volume evacuators (HVE), which are more effective than low suction. This arm serves as the comparison or standard-of-care group against which other interventions are evaluated.

DEVICE

high & low suction

Participants in this group receive both high-volume and low-volume intraoral suction simultaneously. The combined use aims to optimize fluid and aerosol control, with high suction capturing larger volumes and low suction assisting in continuous evacuation.

DEVICE

extra-oral suction & low suction

This group receives a combination of extra-oral suction (a device placed outside the mouth to capture aerosols at the source) and low-volume intraoral suction. This setup is designed to reduce airborne particles during procedures by controlling both intraoral and environmental aerosols.

DEVICE

Extra-Oral Suction and Intraoral Suction

This group is treated using both extra-oral suction and intraoral suction, likely high-volume. The dual approach targets aerosol containment both at the oral cavity level and in the surrounding air, representing a comprehensive strategy for infection control during aerosol-generating procedures.
