biostream® ZERO for the disinfection of treatment units at dentists

biostream® ZERO for the disinfection of treatment units at dentists.

The complete disinfection of treatment units serves the safety of your patients!
biostream® ZERO is not only characterized by an excellent antimicrobial efficacy profile, but also possesses optimal properties from the point of view of application technology. For the disinfection of dental chairs, the active ingredient hydrogen peroxide is usually recommended by the manufacturer.

However, unlike biostream® ZERO, hydrogen peroxide is only a weak oxidizing agent and must be dosed 25 times higher to have the same effect. In addition, the Drinking Water Ordinance stipulates that hydrogen peroxide must be rinsed out almost completely after disinfection, in contrast to biostream® ZERO. This aspect is particularly important from an economic point of view, as each additional rinse causes higher costs.

Here you can rely on the active ingredient of biostream® ZERO, which can remain in the drinking water in accordance with the EU Drinking Water Directive. It is used directly in the dental chair. It makes no difference whether a permanently installed disinfection unit is used or the so-called bottle-care system: Hygienically safe drinking water should be available throughout the treatment unit. biostream® ZERO effectively disinfects the entire treatment unit and the associated contra-angle handpieces, turbines and, of course, the entire water-carrying lines.

The material compatibility of a disinfectant plays a special role from an economic point of view when disinfecting objects with a high material value. And here, too, biostream® ZERO can score points:
The optimized pH value virtually eliminates corrosion. This outstanding material compatibility, coupled with its extraordinary disinfection effect without the formation of germ resistance, makes biostream® ZERO the agent of choice when it comes to effective disinfection of treatment units.

Fungi, algae, viruses and pathogenic germs are effectively combated and killed by the drinking water-approved active ingredient. In technical terminology, these germs are called pseudomonads (Pseudomonas), E.Coli and Legionella.

Hygiene requirements for the reprocessing of medical devices:

The recommendations for drinking water in dental treatment units are defined by the Commission for Hospital Hygiene and Infection Prevention (KRINKO) at the Robert Koch Institute (RKI) and the Federal Institute for Drugs and Medical Devices (BfArM) and are clear. The dangers of germs in treatment units are well known.

As early as May 2015, the State Dental Association of Thuringia published an information sheet entitled „Hygiene inspections and controls in accordance with medical product legislation in dental practices“ – among other things, this addresses the water-carrying systems of treatment units. The Baden-Württemberg State Health Office (BW) also addresses the problem of germs and biofilm formation in its leaflet „Information on water-carrying systems in dental treatment units (dental units)“.

Based on the health authority’s own experience (LGA BW), it is recommended to have water samples taken about every six months to a quarter, depending on previous findings, and to have them tested not only for colony-forming germs – but also for Pseudomonas aeruginosa, since this germ is held responsible for biofilm formation. „Examinations for Legionella need not be carried out more often than once a year if the previous findings did not provide corresponding evidence of germs,“ the LGA BW also informs.

Against these dangerous biofilms, biostream® ZERO has already been used in (dental) practices for years. You too can effectively combat germs, viruses and bacteria in your dental practice. The active ingredient of biostream® ZERO is also approved for use in so-called bottle care systems.

FEEDBACK FROM THE DENTIST’S PRACTICE:

Dentists regularly inquire with biostream® GmbH when findings of e.g. Legionella have been detected in the treatment units and ask how to effectively combat these viruses. The treatment unit must be disinfected as quickly as possible to avoid interruption of operation. Unfortunately, often the support from the dental depots does not bring the expected solution to the problems, because precisely there is not the understanding and knowledge on the subject of „disinfection of drinking water in treatment units“. And if you take a closer look, hydrogen peroxide solutions are recommended, for example, which, however, are not even mentioned as disinfectants according to the current drinking water regulations.

Our cooperation with dentists has shown that there are numerous problems in the area of disinfection of treatment units. In the following, we report on some cases that may also be familiar to you. (We will regularly add to these examples).

Current case:
A dentist from Göttigen, who has been dealing with the topic of „disinfection of treatment units“ for years, had a problem with Legionella after switching to the Bottle Care system. After using biostream® ZERO according to our dosage recommendation, no more legionella could be detected. The dentist was very satisfied and informed us of this at short notice. After one week, however, a recontamination of the treatment unit was detected and the dentist’s feedback was accordingly negative. The effectiveness of biostream® ZERO for disinfecting dental treatment units was questioned.

Since this recontamination with Legionella within one week after application of biostream® ZERO is extremely unusual and has never occurred before, our assumption was that there must be so-called dead lines directly in the treatment unit. Dead lines are line sections at the end of which no pick-up device is connected.

The dentist then contacted his dental depot and asked whether there were dead lines in his dental unit (treatment chair). The answer from the dental lab was „No!“. The dentist then requested a detailed on-site examination of his unit and agreed that if NO dead lines were detected, he would cover the cost of the examination of his dental unit. If dead lines were detected, the dental depot was to cover the cost. The dental depot agreed and a complete examination took place on short notice. It was discovered that there were 2 x 30cm water lines in the dental unit that had been installed for the operation of a second treatment unit. However, since the dentist did not need a second treatment unit on the chair, this had not been installed, but the 2 x 30cm water hoses were still present.

And it was precisely these hoses that had ensured that disinfection did not work: perfect disinfection of the treatment centers can only work if ALL lines carrying drinking water can be wetted with disinfectant.

Disinfection is not possible with dead lines! Why?
In the case of dead lines, a disinfectant cannot enter the water line. It is therefore a dead end. There is no flow that can flush a disinfectant into this dead line. For this reason, even biostream® ZERO could not control Legionella in the dead lines in the case just described.

In accordance with the agreement between the dentist and his dental depot, the dental depot naturally assumed the costs for the inspection of the treatment unit. After removal of the 2 x 30cm dead lines, no more legionella could be detected.

GERMS IN DRINKING WATER AT THE DENTIST DESPITE REGULAR DISINFECTION BY DENTALDEPOT

Have you ever wondered why you contact your dental depot contact person for disinfection of your dental units / dental chairs at regular intervals, why he then carries out the disinfection at your premises and why, nevertheless, during an official inspection or test by the health department or the trade supervisory office, objections are found which result in the decommissioning of your dental units?

Our experience with some (not all!) dental depots has shown that they rely only on the disinfectants recommended by the dental unit manufacturers. These disinfectants are 80% based on the active ingredient hydrogen peroxide. However, hydrogen peroxide is only mentioned in the drinking water regulations as a weak OXIDANT and from a purely chemical point of view – according to DVGW guideline W291 – it can only be as effective as the active ingredient used in the biostream® products if it is used in a concentration 25 times higher.

Then it’s a simple math problem: multiply the current price of your disinfectant by 25 and see how much you pay for a 250ml bottle of biostream®-ZERO.

Our solution for you: Without the use of expensive dosing technology, you can disinfect your dental units effectively with the mostly available rinsing programs! All you need to do is to replace the existing products or those recommended by the manufacturer (mostly based on hydrogen peroxide) with biostream® ZERO.

Although we do not advertise in dentists‘ media and are not a participant in the „International Dental Show (IDS)“, we were able to convince numerous dental depots and also dentists – without advertising – of the effectiveness of our product biostream® ZERO.

dr-werlein​LEIBNIZ UNIVERSITY OF HANOVER CONFIRMS EFFICACY

A study commissioned by biostream® GmbH and conducted by the Institute of Food Science and Ecotrophology at Leibniz University in Hanover under the leadership of Dr. rer. nat. H.-D. Werlein confirms in 1,620 individual tests that the product biostream® ZERO is 99.9% effective against germs occurring in drinking water with exposure times of only 5 minutes.

The biostream® products have been used successfully since 2001 for disinfection in rail vehicles and on ships, in numerous hospitals and clinics, and by well-known beverage manufacturers in practice. Tests at the Institute of Food Science and Ecotrophology at Leibniz University in Hanover under the leadership of Dr. rer. nat. H.-D. Werlein again confirmed the excellent efficacy. Dr. rer. nat. Hans-Dieter Werlein is responsible for the area of food hygiene and microbiology.

biofilm-uni-hannoverSUSTAINABLE CONTROL OF LEGIONELLA AND BIOFILMS

Legionella (e.g. Legionella pneumophila) are a water hygiene problem that is often underestimated. They are also the cause of legionnaires' disease (legionellosis).

Legionella settle in the so-called biofilms, which can only be combated poorly or not at all by e.g. disinfectants containing hydrogen peroxide. Chlorine also has less disinfecting power than the active ingredient chlorine dioxide present in our products.

According to the current Drinking Water Ordinance, biostream® products are approved as disinfectants for drinking water. In addition, our products comply with the current requirements of the Biocide Directive.

 

FROM SMALL CONTAINERS TO TANK TRUCKS - THE CHOICE IS YOURS!

Our customers combat biofilms, viruses and bacteria in very different application scenarios: The dentist worries about his treatment unit and the yacht owner or camper cares about the perfect hygiene of his water tank. But our products are also used in industry to combat Legionella and E.Coli.

The biostream® products are available in different container sizes and packaging:
We deliver as individually as necessary. For example, biostream® asepticaPRO is available in small 10ml vials that require very little storage space and are therefore ideal for travel and outdoor expeditions.

All biostream® products are approved as disinfectants for drinking water according to the current Drinking Water Ordinance and comply with Article 95 (2) of the Biocide Regulation (Regulation (EU) No. 528/2012).

With the biostream® concentrates based on chlorine dioxide, you now have the possibility to reliably disinfect drinking water tanks, drinking water-carrying pipes and drinking water bubbler bottles. Use the active ingredient of the waterworks without expensive technical expenditure.

The active ingredient in biostream® products (chlorine dioxide) has been used to disinfect drinking water in waterworks since the mid-1950s. Complex and expensive equipment is used there for its production, which is now no longer necessary. Simply produce the effective chlorine dioxide yourself and benefit from the perfect effectiveness against E.Coli, Pseudomonads and Legionella!

Disinfect drinking water pipes, dispensing systems and tanks in mobile homes, camping vehicles and on boats and yachts in compliance with the law.  Germ-free drinking or process water for industry and commerce can be easily implemented with the concentrates of biostream® GmbH - contact us. Our products are also suitable for the disinfection of drinking water in times of crisis, for emergency preparedness in case of blackout, power failure and other catastrophic events.

HYDROGEN PEROXIDE AND AGENTS CONTAINING SILVER ARE NOT AN ALTERNATIVE

The biostream® products ZERO and asepticaPRO comply with DIN 2001-2:2009-04 (drinking water supply from small systems and non-stationary systems) and they are effective over the entire drinking water pH range. Hydrogen peroxide is not mentioned in the DIN as a disinfectant - also in the current UBA list of the Federal Environment Agency hydrogen peroxide is only mentioned as an oxidant - but not as a disinfectant.

Take a look at the label of the disinfectant you are currently using: If you find hydrogen peroxide as the active ingredient there, then according to the Federal Environment Agency you are NOT using a DISINFECTING AGENT but an oxidizing agent which, according to DVGW worksheet W291, must be dosed 25 X more strongly in order to achieve the same effectiveness as the active ingredient in the biostream® products.

And if your product also contains silver: Silver is also not mentioned as a disinfectant but only as a preservative. In addition, the following note on this can be found in the DIN: "Only in exceptional cases when storing drinking water without consumption for a longer period of time. Preservation does not replace any necessary disinfection of drinking water that is not in perfect condition."
