Adapting To The New Normal In Dentistry: The Extraoral Suction
Dentists caring for patients afflicted with numerous new and re-emerging viruses have become more aware of the dangers they may face, particularly through aerosol transfer. Many human infections are known to be transported by aerosol. The spread of microorganisms from one person to another by aerosols, resulting in infection, is known as airborne transmission. Aerosols are a suspension of solid or liquid particles in the air with particle sizes ranging from 0.001 to more than 100 micrometers.
There are many viral, bacterial, and fungal diseases which are transmitted via aerosols. Viral diseases presented are influenza, severe acute respiratory syndrome (SARS), Norwalk-like viruses (NLVs) & hantavirus disease, etc. Airborne microorganisms within the clinical or hospital environment can potentially cause infection in susceptible patients, doctors and staff members.
If improved protection can be achieved through the use of environmental management approaches, all dentists & clinical staff who come into contact with these patients will get benefited.
The Reason Behind the Use of Extraoral Suction:
As per OSHA guidelines, the following dental equipment is known to generate aerosols more causing airborne contaminations:
- Air Rotor
- Air polisher
- Ultrasonic Scaler
- 3-Way syringe
The Extraoral Suction Unit removes a large volume of droplets and aerosols created during Dental treatment by using high suction pressure. Fortunately, this form of Infection Control strategy is well-established in existing infection control procedures and is thought to be more effective than other typical methods.
Merits of Extraoral Suction in dental practice:
- External Oral Suction Device safeguards respiratory health by reducing the risk of cross-infection between the doctor and patient.
- Minimizes dental aerosols in the operatory.
- Improves air filtration using medical-grade filters
- Acts as an aerosol scavenger with its powerful suction evacuation
- Increased patient confidence shows that you care about their safety
- The most advanced form of aerosol elimination and air purification.
How Extraoral Suction helps purifying the aerosol?
Extraoral Suction is designed with a 6-Stage Filtration System. The largest droplets will be absorbed with the Pre-Filter Stage. The second filter is an activated carbon layer for absorbing the aerosols. Now the next stage comes of Primary HEPA H13 that captures tiny particles up to 0.3-micron size. After passing through the HEPA Filter, the aerosol particles travel through the UV-C Filter that successfully eliminates all types of microbes by destroying the RNA/DNA. Then Plasma Ion generator layer makes the use of hydroxyl production for total destruction of the microbes that get released to the air as water vapour. The final filtration is done with the secondary HEPA H13 layer that absorbs all the positive ions and the purified air is then released to the clinical atmosphere. The final result is pure and clean air which is safe for the doctor as well as the patient.
