300 is a must

Best protection against aerosols through intraoral spray mist suction

Risk of disease transmission in dentistry

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 (Peng et al., 2020).

From Spray Mist to Aerosols

The use of high-speed instruments and powder jet handpieces generates spray mist
Spray mist is a mixture of cooling water, particles, powder, splashes, droplets of different sizes, saliva, blood and microorganisms
If the spray mist is not correctly aspirated within the patient's mouth, an aerosol cloud will be formed, which spreads over a radius of several meters

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

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

This is what matters:

Suction volume

High suction volume of >300 l/min at suction handpiece

Suction device

Robust suction engines for reliable function in continuous operation

Suction cannula

Working with a large suction cannula with secondary air inlets for maximum suction volume at the cannula

Aerosol reduction

Working with a saliva ejector only or venturi system (volume flow < 200 l/min) is not sufficient to reduce aerosols*

Our recommendation

High Performance Spray Mist Suction systems

The best performance for your daily work.
