Unworn masks and masks provided to us after having been worn conformable to law (mandatory wearing of masks) served as test objects. In order to identify the distribution of living microorganisms on the surface of a mask dependent on exposure time and distance from the human face we conducted a staining study using the bengal rose method. The regular deposition of living microorganisms on artificial mask surfaces was more intense in the areas close to the mouth and nose. A time dependent accumulation was larger on the inside in comparison to the outside of the mask, even if the mask was not worn but only left in the room. The most interesting finding was the ability of microorganisms to penetrate all layers of the mask. We therefore conclude that masks are a suitable substrate for the cultivation of germs, even when not worn. Colonisation increases with human use and with time.

The objectives of this study were to characterise the particle size distribution of aerosols generated by standard dental aerosol generating procedures (AGPs) and to assess the impact of aerosol management interventions on ‘fallow time’. Aerosol management interventions included combinations of high-volume intra-oral suction (HVS(IO)), high volume extra-oral suction (HVS(EO)) and an air cleaning system (ACS). A sequence of six AGPs were performed in succession on a phantom head. Real-time aerosol measurements (size range 0.0062 – 9.6 µm) were taken using a high-resolution particle sizer acquiring air samples from six locations within a typical dental treatment room (35 m3). The majority (>99%) of AGP particles were < 0.3 µm diameter and remained at significant levels around the dental team during the AGPs. This emphasises the importance of personal protection equipment, particularly, the use of properly fitted respiratory protection to the appropriate (FFP3) standard. In the absence of active aerosol management interventions, AGP particles were estimated to remain above the baseline range for around 25-31 minutes from the end of the sequence of procedures. It was found that HVS(IO), either alone or in combination with the ACS, reduced particle concentrations to baseline levels on completion of AGPs. These data indicated that there is scope to reduce fallow time to 0 minutes.
