The wearing of a mask for the practitioner avoids direct contamination, but what about the external surfaces ?
Propelled in the air, viruses and bacteria are very mobile, flow from one room to another, borne by the movement of people. Hence, clothing, surfaces and instruments become the vectors of infectious agents. The dental surgery is a place filled with instruments and care equipment which are – directly or indirectly – in contact with the general public.
This equipment requires a very high quality viral and bacterial disinfection.
When they are being used, the instruments (turbine, hand piece, scaler, etc) yield a host of germ-carrying aerial projections, such as saliva or blood. After having been in suspension in the air, these particles deposit on all the surfaces of the room.
Manual cleaning is tedious and results only in a medium quality job as it is not always easy to access all the surfaces needing to be treated. The difficulties of this job often result in uneven decontamination. Ensuring that all surfaces of a dental surgery are aseptic is essential to avoid any potential for contamination.
