DENTAL UNI T Decontamination of the process water Protection from biofilm and limescale Cleaning of the suction system

Dental unit waterline treatment Protection from biofilm and limescale Biofilm and limescale: No, thanks! Studies of the Institute of Medical Microbiology and Hygiene at the University of Vienna show that the contamination of dental treatment units with microorganisms marks a long-standing and severe problem. Characteristics such as temperatures of 37°C within the pipe systems, relatively long standing times and backflow in handpieces promote the growth of bacteria and fungi, which can cause microbial contamination of the process water as well as of the water-bearing pipes and suction hoses....

Dental unit waterline treatment Decontamination of dental process water Water as a health risk Dental process water shows massive contamination after longer stagnation phases. It is therefore strongly recommended to rinse the water-bearing pipes before first use after longer stagnation phases. This measure alone, however, does not suffice for the supply of hygienically clean process water at any time. Only a continuous decontamination device guarantees that no microorganisms can settle in the pipe systems of the dental unit even after longer stagnation phases (e.g. at weekends). No chance...

WEK/WEK Light water decontamination systems Permanent decontamination of dental process water The water decontamination systems WEK/WEK Light are systems which effectively prevent limescale and decontaminate the process water of water-bearing pipes with the help of the GREEN&CLEAN WK disinfectant. This solution has been specially developed for WEK/WEK Light. METASYS WEK/WEK Light are generally used to supply numerous consumers (e.g. syringes, turbines, or water glass fi ller) in the dental unit with decontaminated water. The German Technical and Scientific Association for Gas and Water...

BR biofilm removing system Intensive decontamination and biofilm removal Dripping instruments or unpleasantly smelling water are usually the first signs that something is wrong with the water-bearing pipes of the dental unit. The most common cause for this is biofilm on the inner surfaces of the pipe system which contaminates the dental process water. Biofilm is not only a source of infection but may also damage dental units and instruments, e.g. hand and angle pieces. The water decontamination systems WEK/WEK Light prevent the formation of biofilm. Prior to the installation of a WEK or WEK...

H1 hygiene system Cleaning, deodorization and defoaming of the suction system Risk caused by backflow The Robert Koch Institute points out that the backflow of cooling water, blood and saliva may enter the patient‘s mouth. If a suction cannula is blocked by sucked in soft tissue, a backflow of contaminated liquids can enter the patient‘s oral cavity through the suction pipe. This presents a risk of infection (cf. Recommendation on Infection Prevention in Dentistry, Hygiene Requirements, 2006). The METASYS H1 hygiene system effectively prevents this path of infection. Using specially...

H1 hygiene system Proven efficiency Two suction systems - one of them equipped with the METASYS H1 hygiene system - have been part of the following experiment. A test solution, enriched with microorganisms (each 108 KBE ml-1), was sucked into both of the systems. Afterwards the suction tubes were flushed with a sterile, watery solution. The rinsing solution was then collected in a sterile container and examined in regard to its microorganisms (cf. Prof. Dr. Dr. Gräf, Institute for Medical Hygiene at the University of Erlangen-Nuremberg, Germany). The sample taken from the suction tube...
