Aerosol generating procedures (AGPs) constitute a big part of the work that dental clinics do. The aerosols generated as a result then need to be extracted. Now, you may wonder about the need for dental aerosol extraction. Surely, it must be okay to wipe the surfaces after the procedure is complete and the aerosols have settled?

The problem is, these aerosols can be hazardous to health if they are inhaled.

Dangers of Inhaling Dental Aerosols

Dental aerosol is made up of different types of particles. These can include fine particles from the teeth, blood, mucosal cells, saliva, as well as the bacteria and fungi present inside the patient’s mouth. When the dental aerosol generated is finer than 1 micrometre, these particles can be inhaled straight into the lungs.

When these foreign bodies enter the respiratory passage, they can irritate the lining of the nose, throat and lungs. Now, we have discussed the dangers of inhaling airborne particles at length, ranging from nail dust in beauty salons to exhaust fumes to metal dust and fumes. The gist of it is that prolonged exposure to fine particles can lead to nasal irritation, coughs, occupational asthma, and in some cases, cancer.

Then, there’s the risk of infection from the bacteria and fungi. These microorganisms may be living inside infected teeth or the oral cavity (which is a fancy way of saying ‘the mouth’). Once airborne through AGPs, they can then infect anyone in the room.

Risk of Coronavirus

Recent events have also made us aware of the risk of viruses that could be transmitted through the air. These microbes are carried within a fine mist of saliva or mucous and can go directly into people’s airways and into their lungs.

To prevent the virus from spreading rapidly, the Government had to enforce a lockdown, where businesses, including dental clinics, were shut down. As they gradually open up again, they need to make sure they have measures in place to keep employees and customers safe.

In such a situation, it is even more important for dental clinics to invest in extraction for AGPs. Since AGPs can help the spread of the virus, this is something dentists will need to think about before they start seeing patients.

Whilst dental surgeries have been given the green light to re-open by the government, it’s not just a case of opening their doors to patients.

How Does Covid-19 Change the Way Dental Clinics Operate?

Because of Covid-19, it is now more important than ever to ensure dental practices are prepared to keep dentists, employees and patients safe.

This is why VODEX has been working hard behind the scenes, consulting with leading dentists and associations to provide AGP extraction solutions for practices across the UK.

Our Findings for Dental Aerosol Extraction

Here’s what we found out.

Wet Extraction

Dental AGPs tend to be water-based, generating wet aerosol, so the extraction for AGPs cannot be the same as dry dust extraction.

Portable extraction

Dental AGP extractors need to be portable and light, so they can be positioned in the best spot to extract aerosols without getting in the way of the procedure.

Antimicrobial Filters

Since the filters will get wet, they need to have an antimicrobial treatment to prevent bacterial growth, mould, and resultant odours.

Proper Suction Arm

The suction arm needs to be light and easily manipulated. It should have the right type of nozzle for efficient dental aerosol extraction at the source.

Using these findings, we developed the VODEX DentalAIR DA1001 extraction unit and the DentalAIR UVC® extraction unit for dental aerosols.

Features of DentalAIR DA1001

4-Stage Filtration

DentalAIR comes with a comprehensive 4-stage filtration to ensure complete dental aerosol extraction. The unit is, therefore, able to capture fine dust as well as fumes and vapours. It includes:

  • A unique antimicrobial, hydrophobic, washable polyester mist eliminator
  • An evaporating plenum box with a moisture-resistant synthetic filter
  • H13 HEPA filter (to eliminate 99.95% particles of 0.1 micrometres to EN1822 standards)
  • Special-blended DenCARB® carbon filters to absorb any vapours or smells

All HEPA and carbon filters used in this extraction unit have been manufactured and certified in the UK or the USA.

Flexible Arm

It has a 1.5m long multi-positional silicone arm with 50mm diameter and a flared nozzle. Plus, it has no unsightly ducting running across the room.

Mobile Unit

The unit is small, measuring 410mm x 425mm x 250mm (HxWxD). It is much lighter, and quieter, than any others in the market, and comes with locking wheels so you can move it around easily.

High Suction

Since dental aerosol extraction needs to catch all airborne particles before they get a chance to escape out of the suction zone, the DentalAIR® unit comes with high-suction with 300m3/hr airflow.

Easy to Maintain

The unit comes with filters that are easy to change. It also uses very little energy to run – 210W, using 230v or 115v single phase.

Regulations Compliant

The unit meets all COSHH and HSG258 standards and is CE approved.

Plus, you also get a new capture hood called AeroSHIELD®, which creates a partial enclosure and a clear PETG optically-correct physical barrier between you and your patients.

 

Features of DentalAIR UVC®

The DentalAIR UVC® is an upgraded model of the DentalAIR unit. It has all the features of the standard model, but with a 5-stage filtration process. The fifth filtration stage is a UVC filter sterilisation module with a safety interlock that uses ultraviolet light to kill microorganisms, giving your dental clinic another layer of protection in addition to the extraction for AGPs.

Both these units are ready for pre-order, so if you think you need them for your dental clinics, get in touch with us on sales@vodex.co.uk and speak to us. We will be able to advise you on how to make the air in your clinic safer for everyone.
