- What is the best protection against dental aerosols?

What are aerosols?
Aerosols are a mixture of cooling water, particles, powder, splashes, droplets of different sizes, saliva, blood and microorganisms.

How are aerosols at the dentist formed?
The spray mist is created through the use of high-speed instruments and powder jets. If the spray mist is not properly sucked off in the patient's mouth, an aerosol cloud is created within a radius of several meters.

Dental personnel is constantly exposed to a wide variety of microorganisms. Potentially hazardous pathogenic microorganisms include: e.g. HBV, HCV, HIV, staphylococci, streptococci, mycobacterium tuberculosis, herpes simplex virus etc. People working in dentistry have the highest risk of contracting corona

The risk:
- Over 600 different types of bacteria can be detected in the human oral cavity.
- 1 ml of saliva contains about 100 million bacteria.
- During a 15-minute treatment without protective measures, 0.014 µl - 0.12 µl saliva is inhaled via the aerosol.
- High risk of infection for patients due to cross contaminations.

The solution for dentists:
- Intraoral high-performance spray mist suction with 300 l/min for up to 100% aerosol reduction.
- An intraorally applied flow rate of 300 l/min is the most important factor.
- To achieve this, a large suction cannula must be used.
- Optimal suction technique directly at the treatment area improves the effect.

DÜRR DENTAL's recommendation to avoid aerosols in the dental practice:
- High Performance Spray Mist Suction systems
- Mobile Spray Mist Suction unit
- Large suction cannulas for a maximum suction volume, e.g. the DÜRR DENTAL aerosol cannula.

This is what counts when avoiding aerosols:
- High suction volume of more than 300 l/min at suction handpiece.
- Robust suction engines for reliable function in continuous operation.
- Working with a large suction cannula with secondary air inlets for maximum suction volume at the cannula.
- Working with a saliva ejector only or venturi system (volume flow less than 200 l/min) is not sufficient to reduce aerosols.
