tweezers etc.
Any deposits such as dental cement, composite, polishing paste or
similar must be removed immediately after examination of the patient,
e.g with a swab, before it hardens.
Instruments with particularly complex functional ends or very stub-
born deposits may require ultrasonic pre-treatment.
To avoid injury from double-ended instruments or upright instru-
ments with upward-facing probes, the washer-disinfector should
be loaded from rear to front, and unloaded from front to rear.
After thermal disinfection, manual secondary cleaning can be done
according to relevant bio-substance regulations without danger of in-
fection, although the process must be monitored as necessary.
Mouth specula
Risk of damage due to machine reprocessing.
Not all glass mouth specula can be reprocessed by machine.
Always follow the manufacturer’s instructions.
Rhodium-coated mouth specula, because of their delicate surface,
must be loaded in such a way that the mirror surfaces cannot sustain
mechanical damage during reprocessing, e.g., by knocking against
other instruments.
Mouth rinse cups
Mouth rinse cups should preferably only be reprocessed in the upper
basket. There is a greater risk of stress cracking and corrosion in the
lower basket due to larger temperature fluctuations and risk of me-
chanical damage.
Opal glass is particularly suitable for reprocessing in the machine.
