Maintenance - Aftercare and maintenance
Unfortunately, no device can be used without maintenance. The importance of proper maintenance is that the risk of defects and shortcomings becomes as small as possible.
In the event of a malfunction of the thermodisinfector, the ultrasonic cleaning device together with the 'old' bin with disinfectant must be immediately available. If the type B autoclave does not work for a while, but the thermodisinfector and hand and corner piece cleaner do, continuity can be guaranteed, except for surgical treatments. If necessary, the surgical instruments can be sterilized at a neighboring colleague (packaged). They must be transported in dry, tightly sealed plastic boxes after sterilization.
Maintenance of equipment and treatment rooms must be distinguished in annual maintenance and more frequent operations or even daily recurring maintenance.
'During periodic maintenance by the manufacturer or dental depot, a maintenance report is necessary (and that is different from the invoice). You can compare it to the APK inspection of cars: a report that states what one has looked at. In addition, an account is issued separately (JJJ van Foreest, dental health inspector).
These instruments are used for the removal of tartar in the form of a stand-alone device with its own water and power supply. The extra pedal is sometimes an obstacle to the operation, because it has to find a good place in the limited space under the treatment chair. Nevertheless, much use is made of such loose equipment.
A Standalone tartar remover requires intensive care to maintain water quality. B Vulnerable water supply of standalone ultrasonic tartar device
If the Cavitron or EMS is used as standalone equipment, the water quality must be carefully monitored!
Clean the water tank after each working day, disinfect with a 0.1% chlorine solution and leave dry.
Maintenance of the treatment unit / chair
The treatment unit / chair is serviced every year by the supplier or manufacturer (APK).
- Immediately flush the suction hoses after bloody interventions with cold water to prevent blood clotting on the inside of the hoses.
- Rinse the suction hoses at the end of the day by collecting a detergent / disinfectant in lukewarm water in the hoses. The choice of detergent / disinfectant depends on the instructions of the manufacturer. When applying an improper detergent / disinfectant, foam may cause a malfunction in the exhaust unit's motor.
- Clean disposable gloves should be worn when cleaning or replacing the strainer or the suction unit hoses.
- When replacing or cleaning the amalgam separator, sturdy disposable gloves should be worn.
- Clean the spittoon thoroughly with a brush and disinfect it.
- Apply Legionella prevention.
- Disinfect and / or rinse the piping system after a longer period of standstill (weekend / holidays) according to the manufacturer's instructions. The unit usually remains a weekend with the disinfecting liquid in the pipes; see further quality policy of water from the treatment unit.
- Do not actively heat the water in the pipes of the unit unless effective measures have been taken to prevent bacterial growth.
- Replace sieves and filters weekly, or more often if necessary. Do not actively heat the water in the pipes of the unit unless effective measures have been taken to prevent bacterial growth.
Disinfect the water pipes of the treatment unit
Replace sieve with the extraction unit. Think about protective glasses, mouth-nose mask and sturdy disposable gloves!
Maintenance of the thermodisinfector
Perform the user maintenance and checks according to the manufacturer's instructions and document this.
Have periodic maintenance and inspection measurements - at least annually - according to NEN standard R8154 by the supplier or manufacturer and document this.
There is a distinction between powder and liquid dosage. The machine indicates when it needs refilling at the liquid dosage. Powder can therefore be forgotten and is less reliable. Liquid detergent / neutralizing agent and rinse aid are indicated by the machine. It also indicates when the salt needs to be refilled.
Stock chemicals with automatic dosing device of the thermodisinfector
For the liquid dosing of the detergent, carefully read the instructions for venting the dosing hoses.
The filter must be replaced with the thermodisinfector with integrated hot air drying. The filter is opened at the inspection panel at the bottom of the device, after which it can be exchanged.
The machine indicates when the filter needs to be changed. This depends on the number of batches. Normally this is taken into account with the annual maintenance.
Maintenance hand and corner piece cleaner
Provide the equipment with the required consumption fluids in time. Most devices require professional maintenance by a technician.
In addition, every week a special cleaning tablet should be used in the device to keep the inside clean.
Maintenance of the autoclave
Have periodic maintenance and inspection measurements carried out in accordance with NEN standard R8153 by the supplier or another company accredited by the manufacturer and document this.
Maintenance what you can do yourself:
- Clean the boiler house by removing the trays and the housing of the trays. Cleaning should never be done with abrasives.
- Fill in demineralized water on time. Older autoclaves use the water that has been heated to steam over and over again in a closed system. Refilling is then not often necessary. However, the water must be refreshed periodically. However, some new autoclaves use new (demineralised) water for each cycle. Many liters per week must then be added. Of course the water never needs to be refreshed...
- Change the water at autoclaves that reuse the water (via the outflow opening using a tap and the flexible hose supplied).
Fill demineralized water and refresh it periodically if it is reused by the autoclave
Maintenance to hot water baths
In the Infection Prevention guideline in dental practices, the following is included in the maintenance of hot water baths. The water in the hot water bath to melt platelets is a potential source of contamination.
- Empty the hot water bath at the end of each day.
- To prevent contamination of the water, do not put your hands in the water.
- To prevent contamination of the water, wax plates must only be placed in the bath with a worktop tweezers and removed in this way.
- Material that has been in contact with a patient (objects or wax) may only be re-done in the hot water bath 'au bain-marie'.
Hot water bath needs strict hygiene
Domestic maintenance is a form of practical hygiene that has a rather invisible relationship with infection prevention. Nevertheless, it is part of the daily activities to keep the practice clean and clean in the home.
Recommendations for floors, furniture and sanitary:
- Record the maintenance cleaning activities of the practice rooms in a cleaning protocol.
- Evaluate the cleaning result regularly and adjust the protocol if necessary.
- Use as many disposable materials as possible for cleaning and disinfection.
- Clean and dry cleaning materials after work.
- Wear sturdy disposable gloves during cleaning.
- Clean the non-critical areas, except the bathroom, at least once a week.
- Empty pedal bins and waste bins daily.
For household work in practice, all cleaning cloths may only be used once! This means that they are thrown away as often as possible or after washing and drying on the heating in the laundry go to at least 60 ° C.
For a comprehensive and up-to-date state of affairs, please refer to the website of the VGT (www.vgt.nl). There you can find information about the cleaning agents that are available in practice. On the updated site the application area of the drug can be read and it can also be seen whether the product is (still) permitted.
- Treatment room: wipe worktops, flush unit, clean floor preferably with a dust wiper. Remove any contamination with a wet tissue. Clean the floor wet once or at most twice a week. Empty the trash cans from the treatment rooms. Dispose of the waste in sturdy plastic garbage bags with the normal household waste.
- Sanitary: check the staff toilet and patient toilet on a daily basis and, if necessary, do extra cleaning. This also applies to the bathroom where the teeth can be cleaned.
A Cleaning furniture requires daily maintenance. B Choose in the waiting room for practical toys that are removable and take little time every day to clean up. Clean the toy at least once a week
- Use clean dish towels and dishcloths every (wash) turn. Always allow them to dry thoroughly first and then store them in an air-permeable laundry basket. Of course, only paper towels are used in the toilets. This is also an option for the staff room. If, after all, traditional towels are used, at least every part of the day a clean hang or better: after every break!
- Leave the administration room tidy for the cleaning crew and empty the bins.

- Carefully remove the cover of treatment chairs and treatment chair. Keep in mind the manufacturer's instructions.
- Cleaning household equipment, telephone and other office items.
- Normal household maintenance of kitchen, toilets and other areas.
- Dispose of residual waste.
- Thoroughly clean toys from the waiting room with ordinary suds.
- Practice room: clean drawers and inserts with soap and take away cupboard handles.
- Dust out storage cabinets and check expiration dates. Material that is 'over time' can often be used well by a local ROC training for dental assistants. Give it differently with the chemical waste.
