Suction
Cannulas – Getting a grip on infection prevention
The DÜRR DENTAL range of suction cannulas and handpieces
The right cannulas enable you to effectively reduce germ-laden aerosols. The powerful range of cannulas from DÜRR DENTAL protects the entire practice team. All cannulas in the DÜRR DENTAL range share the same basic quality features: they are ergonomically designed and have no edges, making them extremely comfortable for both patients and therapists alike. At the same time, it provides the therapist with optimum grip. All cannulas deliver highly efficient suction performance to remove saliva, blood and micro-particles from the patient's mouth and are therefore well-suited to all types and areas of treatment.
Suction solutions from DÜRR DENTAL are opening up new possibilities in dentistry
It might be routine procedure now, but back in the 1960s treating patients while they were lying down was quite a sensation. It was the systematic dental suction unit developed by DÜRR DENTAL that made this possible. A powerful suction unit is an indispensable piece of equipment for any dental practice, as it improves protection against infection by reliably aspirating spray mist before it is released into the room air. As the inventor and the first supplier of dental suction units, we utilise our expertise to constantly develop new solutions to improve working conditions for practice teams and to provide you with the best possible protection. We have developed a cannula portfolio that meets all the requirements of modern dentistry.
The perfect symbiosis of functionality and design
The DÜRR DENTAL cannula portfolio is one of a kind. With four different types of cannula available in different models and colours, there is always a suction cannula perfectly suited to the patient and application: the universal cannula for adults, the Petito universal cannula, the prophylaxis cannula and the surgical suction cannula. DÜRR DENTAL offers top quality cannulas and accessories for various application areas such as preserving, prosthetic, surgical, endodontic or prophylactic treatments.
These first-class suction solutions are complemented by the innovative Y-Adapter and an extensive range of handpieces.
Safety for practice teams, patients and the environment
The cannulas are ergonomically shaped, have no edges and are therefore comfortable for the patient and practitioner. The cannula design provides optimum grip.
All cannulas are highly efficient at suctioning off saliva, blood and microparticles from the patient‘s mouth. This is the best way to prevent aerosols from spreading.
All cannula types are (optionally) available with special secondary air inlets, which protect patients against the backflow of contaminated patient secretions from the suction system.
The cannulas are autoclavable and are made of a highly durable, resistant material. This helps you reduce waste and protect the environment. This has a positive effect on the profitability of your practice.
Basics: How cannulas protect
The term “reflux” describes the backflow of contaminated fluids from the suction system into the oral cavity of the patient. Backflow of this kind can occur if the suction cannula is blocked by aspirated soft tissue or if the suction hose is held above the patient while the suction power is low. Correct positioning of the suction hose and the use of suction cannulas with secondary air inlets can mitigate such gravitational backflow of contaminated fluids.

If aerosols spread in a practice room, health risks increase. This is because there are over 600 different types of bacteria that can be detected in a human oral cavity. During a 15-minute treatment without protective measures, these enter the room air in the form of a contaminated aerosol cloud and are then deposited over a radius of several meters. These aerosols can be detected in the room air for up to 30 minutes. Door handles, armrests, lights and other surfaces are contaminated in this way. Cross-contamination poses a high risk of infection not only for the practice team, but also for subsequent patients.

The right intraoral suction unit makes an important contribution to infection protection for the dentist, the practice team and the patient. To ensure that as little aerosol as possible is formed, spray mist should ideally be aspirated in the patient‘s mouth and a large suction cannula should always be used. High-volume suction with a suction cannula diameter of at least 10 mm is recommended. A suction cannula with a diameter of 16 mm is ideal. In addition, the chosen cannula should feature optimised flow design.
A suction cannula can only be as good as the system behind it. This means that the performance of a suction cannula ultimately depends on the performance of the suction system installed in the practice. Its suction rate should be around 300 l/min to achieve optimised spray mist suction at each treatment unit. If the performance of suction systems drops, dangerous aerosols can spread. Around half of all systems are affected by this issue and fail to comply with the applicable guidelines.
