Preparation for a treatment - Practical infection prevention at the chair
For each patient, a clean work area is set up on the worktop, consisting of a paper or tray, on which all the supplies are arranged in an orderly manner. This is the clean work field. In addition, a tray or napkin is placed on the road to put used things and materials, the dirty work field.
Preparation for a treatment
At the beginning of the working day
Thoroughly flush the pipes of the unit according to the manufacturer's instructions. Make sure that no mist arises because it forms the infection route for the Legionella bacteria (inhalation poses a risk of developing Legionnaire's disease). Units with bottled water must first be provided with clean bottles filled with fresh water
Between the patients
Patiently wash for 10 seconds in the next patient (immediately) before the start of treatment. Certainly when more time passes between the various treatments (pause, prosthesis work), flushing is important for ten seconds. After a prolonged shutdown of the water in the thin unit pipes, part of the formed biofilm is released during the first flow; the first polluted water must therefore be washed away.
Spray-free flushing of the water pipes
A Disposable tip and hygiene cover (keep the buttons clean, because cleaning is not possible ...). B Combined disposable tip and hygiene cover (sleeve). C Hygiene cover (sleeve) around the control slide and hose of the extractor. D Hygiene cover to the curing lamp. E Hygiene foil around the entire print gun. F Hygiene cover (you) for the timer.
The disposables include:
- Rinse cup;
- Disposable tip on the multi-function syringe;
- Hygiene cover (sleeve) around the multi-function syringe, suction hose, curing lamp, cartridge holder (pressure gun) and timer;
- Suction tubes including sleeves around the suction hose;
- Headrest bag;
- Patient napkin with adhesive strip.
Preparing the tray
If, due to lack of space, there is no opportunity to assemble the trays outside the treatment room, this can be done beforehand on a corner of the worktop for a number of treatments (at least outside the splash zone). The covered trays must then be covered with a lid or patient napkin with plastic backing.
Ideally, ready-to-use trays are located in an easily accessible tray. This tray cabinet consists of two separate parts; a part for the clean trays and a part for the trays with dirty instruments. The laying of the tray then took place at an earlier moment.
In addition to the necessary instruments, there must be a drill block on the tray with suitable drills for a specific treatment. Cotton rolls, matrix bands, wedges, articulation paper and finishing drills and discs must be present in standard quantities

Setting up the worksheet
- For each patient, a clean work area is set up on the worktop, consisting of a paper or tray, on which all the supplies are arranged in an orderly manner. This is the clean work field. In addition, a tray or napkin is placed on the road to put used things and materials, the dirty work field.
- Ensure that a clean worktop or transport tweezer is always available (for repacking stock or an instrument that has fallen on the ground, for example).
- Check that there is sufficient stock of cotton wool rolls, composite compules and matrix bands.
- Ensure that additional materials are available in a tup outside the splash zone (ie on the worktop). Only for the ongoing treatment!
A Tup for extra endomaterials. B Tup for additional crown and bridge materials
- For preparing prints, prepare as many measured portions of alginate as necessary; This prevents possible contamination of the alginate powder by packing. Alginate can also be mixed mechanically in the alginate mixer.

- For surgical procedures in the oral cavity, use a sterile worktop (CH-1, for example inserting implants and impacted elements)
- For surgical procedures in the oral cavity, use a clean worktop (CH-2, for example extraction, gingival corrosion, abscess incision and local mucoperiosteal collapse).
At the end of the treatment, the worktop must be cleaned to remove the settled aerosol from the treatment. To this end, the worktop can be cleaned in-house and then removed with an alcohol wipe.
The stock materials on the worktop must be sealed and can be hand-packed.
- Equip the CCD sensor with an elongated hygienic cover that also covers part of the cable. Unfortunately, the cover can be damaged quite quickly when the directional equipment is placed in the holder. Therefore it is better to choose to place sensor including setting equipment in a hygiene cover.

- Or provide an appropriate number of phosphor plates or analogue X-rays of hygienic foil.
- Prepare all necessary adjustment equipment.
