A Dentist is always the most prone professional person for aerosols transmitted infections including viruses like Ebola, SARS, COVID, influenza, etc. In spite of taking maximum protection like a face mask, head cap, gloves, and apron, he is still prone to aerosol transmitted viral infections.
Aerosols are generated during dental procedures with a high-speed handpiece and an ultrasonic scaler. It will stay for a long time within the range of 1-2 meters around the dental chair. These aerosols get attached to various body parts of the dentist and his assistant.
Need of an ExtraOral Suction:
Like intraoral suction is used for operating site visibility, an extraoral suction is used to absorb and suck all the droplets and aerosols formed during operation procedure. Extraoral Suction helps in controlling aerosols based viruses and microbes transmission. It sucks all droplets and mist produced while using air rotors and scaler tips.
With an extensive medical-grade filtration system like HEPA H13, Plasma ion along with a UV light disinfectant, viral, and germs produced are eliminated.
Extraoral Dental Suction can be a great addition to your safety protocol.
How to choose Effective Extra oral Suction:
Before finalizing an external oral suction one must understand its mechanism. An extraoral suction has two main parts.
External Suction unit: Suction Unit arm length must be long enough to provide enough space to work together with assistant. 4 hand dentistry needs at least 1.5 meters or above suction arm length. Heavy power above 1000 watt gives more power to suck aerosols.
Steriliser unit (Like Air Purifier): To disinfect the aerosols sucked, a good extra oral suction need 4 main filter mechanism. Primary filter+ UV light+ Plasm Ions + HEPA filter.
The primary filter cleans all dust and debris particles mixed with air and water in aerosols. filtered air is sterilized by UV light and all microbes & viruses are killed by UV light. Plasma ions 9 (+ve ions and –ve ions) plays the most important role by discharging and killing these microbes & viruses. It sticks to the surface and increases its size so, that it can be finally filtered by HEPA filter which has a capacity of 0.3 microns. Finally, filtered air comes out which is purely clean. Now, you will get sterilized air for your operative area.
Combine use of Intra and extraoral aerosol suction unit provide maximum results and you can decrease up to 99.9% microbes from your working area during any procedure which creates aerosols.
Determination of the number of droplets and dust
Recently a high quality tested extra oral suction is introduced in India. DS1000 fulfills all the requirements of good extra oral suction. The long working arm length of 1.8 m helps in aerosols filtration and disinfection of system which include primary filter, UV light chamber, Plasma ions generator, and HEPA H13 grade filter which is considered best in the industry can be used safely in the clinic. The use of both Intra and Extra oral suction is highly recommended. So, start using it in your practice and keep yourself and your staff free from all aerosols transmitted infections and diseases.
