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
High suction volume of >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 < 200 l/min) is not sufficient to reduce aerosols*
Our recommendation
High Performance Spray Mist Suction systems
The best performance for your daily work.
