Introduction;
External high volume extraction devices may offer a way to reduce any aerosol particulate generated.
Aims;
The aim of this study was to measure the particle count during dental aerosol
procedures and compare the results to when a High Volume Extraction device is used.
Design;
A comparative clinical study measuring the amount of PM1, PM2.5 and PM10 aerosol particulate with and without the use of an external High Volume Extraction device was undertaken.
Materials and methods;
In total, 10 restorative procedures were monitored with an an industrial Trotec PC220 particle counter.
Interventions;
An external High Volume Extraction device.
Main outcome methods;
The air sampler was placed at the average working distance of the clinicians involved in the study - 420mm.
Results;
In the present study aerosol particulate was recorded at statistically significantly increased levels during dental procedures without an external high volume extractio device versus with the device.
Discussion;
The null hypothesis was rejected, in that significant differences were found between the results of the amount of aerosol particle count with and without a High Volume Extraction device.
Conclusion;
If the results of the present study are repeated in an in vivo setting, an external high volume suction device may potentially lower the risk of transmission of viral particulate.
