How to Clean KaVo Dental Chair?

1. What disinfectants are allowed for cleaning KaVo dental chairs' surfaces, and what precautions should be taken?

KaVo has evaluated and approved the following disinfectants for use:
  • Mikrozid Liquid (manufacturer: Schülke & Mayr)
  • FD 322 (manufacturer: Dürr)
  • Incidin Liquid (manufacturer: Ecolab)
  • CaviCide (manufacturer: Metrex)
Please note that KaVo assumes no responsibility for guarantee, warranty or damage compensation claims which arise from the use of other cleaning agents and disinfectants. Please only ever carry out a wipe-down disinfection.

2. What germ reduction functions and rinse programs are there and how do these work (for dental chairs ESTETICA E70/E80 Vision, E50 Life & Primus 1058 Life, and older models i.e. E70, E80, E50, 1058)?
Due to the fact that the water bearing systems can become colonised by various micro-organisms despite compliance with the standards, regular use of the germ reduction liquid is essential (only for water which comes into contact with patients and in conjunction with the DVGW water block).
In this approach, a distinction is made between the following functions:

  • KaVo continuous germ reduction: By automatically adding KaVo Oxygenal 6 germ reduction liquid the amount of germs in the treatment water is continually reduced.
  • During periods of standstill, vigorous germ reduction hinders the growth of microorganisms. As a result, it ensures that patients have access to clean water. Water-bearing tubes are automatically supplied with a 10x greater concentration of KaVo Oxygenal 6 during the intensive germ reduction. During the aggressive germ reduction program, which lasts about 45 minutes, the higher hydrogen peroxide concentration is active in the system for at least 30 minutes. KaVo suggests beginning the aggressive germ reduction before the weekend, holiday, or other downtime and allowing it to take effect during that period. At the start of the program, the dental chair can be turned off. During commissioning, the gadget is automatically washed until it reaches its usual Oxygenal 6 concentration.
  • All instruments on the dentist and assistant’s unit are rinsed with water every 20 seconds during the shortened rinse program (01). The rinse program (02) automatically rinses the water-bearing system for at least 2 minutes and rinses all of the instruments, including the tumbler filler. This enables a significant reduction in microbial accumulation which occurred during the stagnation period.

3. Does the hydrogen peroxide component in the KaVo Oxygenal 6 germ reduction liquid have harmful effects on human health if swallowed?
In the continuous germ reduction, the treatment water contains only a very low concentration (0.02%) of hydrogen peroxide (H2O2). This presents no harm to human health in this dosage.
4. What should be done if treatment water concentrated with Oxygenal comes into contact with the patient’s eyes?
Firstly, eye contact with a hydrogen peroxide solution should be avoided in any event which requires protective glasses to be worn. If, however, treatment water sterilized with Oxygenal 6 does come into contact with the eyes, they should immediately be rinsed with a large volume of water. Due to the low dosage of 0.02% H2O2 permanent damage is not likely.  
5. How does treatment water sterilized with Oxygenal act during the extraction of teeth?
As hydrogen peroxide is used in human medicine to rinse wounds and in dentistry for the local disinfection of dental tissue and for haemostasis, Oxygenal 6 presents no danger. Recent studies indicate that hydrogen peroxide does not only disinfect, but also activates the immune defence in wounded areas, in which white blood cells reside. This accelerates the healing process.
6. Are there any hydrogen peroxide allergies?
So yet, no cases have been reported, and no sensitivities to hydrogen peroxide have been discovered. Patients who have a known hydrogen peroxide sensitivity are not allowed to drink water treated with KaVo Oxygenal 6.
7. How often does Oxygenal 6 need to be replenished?
This is very dependent on how often the intensive germ reduction is carried out, and how often or with how much water the mouth rinsing sink is filled. In our experience, one bottle of Oxygenal lasts for approx. 4 to 6 weeks.  8. Which disinfectant should be used for the suction and drainage systems on KaVo dental chairs?
A special gel is developed with KaVo Dekaseptol. This product has the function to disinfect the suction system and the service water outlets in dental chairs.
9. What is Dekaseptol Gel?
Dekaseptol gel has a bactericide, fungicide, tuberculocide and anti-viral effect. Furthermore, it is effective against HBV and HIV. It is listed as a disinfectant with VAH and DGHM.
10. How often does Dekaseptol need to be replenished?
For the KaVo HYDROclean hygiene system (only E70/D80) approx. 25 ml of DEKASEPTOL is pumped through the suction tubes into the suction system of the unit. In addition, approx.10 ml of DEKASEPTOL is dispensed into the spittoon bowl. With an average total use of approx. 35 ml per use, one litre of DEKASEPTOL will last for approx. 28 HYDROclean cleaning cycles. For an average usage of once per day (more for surgical activities), the bottle must be filled approximately once per month.
11. Which hygiene measures do we recommend after the treatment of high-risk patients?
  • A surface disinfection of all surfaces contaminated by contact or aerosols with a surface disinfectant tested and approved by KaVo. (Please observe the treatment time stated in the manufacturer's specifications.)
  • Rinse all water-bearing systems as recommended in the current RKI guidelines (approx. 20 seconds).
  • Disinfect the drainage or suction system with KaVo DEKASEPTOL gel.
  • Clean, treat and sterilize all straight and contra-angle hand pieces, handle sleeves, drain tubes, drain tube hand pieces, nibs, manual instruments etc. in accordance with the manufacturer’s specifications.
