Annex 3 MAINTENANCE OF DYNAMIC INSTRUMENTATION

1. External disinfecting

This procedure prevents the risk of infection during cleaning and maintenance.

♦ Wear gloves.

♦ Dampen the instrument with a non-corrosive disinfectant (pH from 2.5 to 9) or with 70-80% ethyl alcohol.

♦ Comply with the disinfection reaction times recommended by the manufacturer.

If any traces of disinfectant are left on the instruments, the latter will become corrosive when heated. This may cause

extensive damage during sterilization: oxidation, modification to the technical characteristics of seals, rubber, fibre

optics, etc.

2. External cleaning

This procedure involves the removal of residues (blood, dentine, etc.) which adhere to critical areas such as spray

outlets, fibre optics, etc.

♦ Use a soft, damp brush and take care not to scratch the surface of the fibre optics.

♦ Remove from the item all traces of the disinfectant used prior to this cleaning phase. This product must only act

over a given time after which it may become aggressive for both instrument and sterilizer.

3. Maintenance

Once the instrument has been disinfected, cleaned and is dry, free from residues, it must be lubricated before, not

after sterilization..

a) Manual lubrication with oil spray

♦ Check the condition of the O-ring on the spray insert. Replace if necessary.

♦ Purge the spray tubes by blowing air into the instrument.

♦ Lubricate using an oil aerosol in accordance with the manufacturer’s recommendations.

b) Automatic lubrication with Assistina: a more economical and more effective solution

♦ Assistina can clean and lubricate dynamic rotating instruments.

♦ The advantage of this equipment: simplified and effective cleaning and lubricating of the mechanical components.

♦ Automatic, optimal injected quantity of oil.

♦ Assistina also cleans and dries the spray tubes, preventing them from clogging.

4. Packaging

In order to preserve sterility, rotating instruments should ideally be wrapped prior to sterilization.

DO NOT

: :

Immerse or vaporise the instruments. Do not allow the disinfectant to come

into contact with the instrument, poor rinsing, etc.

Do not use cloths containing chlorhexidine or aldehydes.

The sterilizer detects and amplifies errors which occur upstream from sterilization
