Description of the machine
High-level disinfection
The G 7881 Dental Thermal Disinfector
is suitable for automatic treatment of
dental instruments and accesories. It
cleans and in the disinfection program
simultaneously thermally disinfects, at
200°F/93°C, instruments and
accessories.
Areas of effectiveness are physical
removal or thermal inactivation of
vegetative bacteria including
mycobacteria, fungi, fungal spores, and
viruses. These categories include the
Mycobacterium tuberculosis and the
Enterococcus faecium.
Important: Only the programs labeled
"Disinfection" disinfect! Only use this
program when handling contaminated
items. All other programs are designed
to clean items without disinfecting
them!
All relevant safety procedures should
be obeyed. Relevant safety procedures
include, but are not limited to, the
Centers for Disease Control's
Recommended Infection Control
Practices for Dentistry and the OSHA
Bloodborne Pathogens Standard.
The G 7881 Dental Thermal Disinfector
achieves high-level disinfection as
defined by the Spaulding
categorization.
The Spaulding category high-level
disinfection is the same type of means
as in the sterilant category except that
the use pattern is different. The sterilant
is used as a high-level disinfectant by
e.g. reducing the exposure time within
its effective range of tuberculocidal,
virucidal, and bactericidal action.

According to the Centers for Disease
Control's Recommended Infection
Control Practices for Dentistry,
instruments should be classified in one
of the following categories and be
treated accordingly:
All critical instrments must be
sterilized after treatment in the G 7881
Dental Thermal Disinfector. Critical
instruments are used to penetrate soft
tissue or bone, e.g. forceps, scalpels,
bone chisels or scales.
Semicritical instruments should be
sterilized after treatment in the G 7881
Dental Thermal Disinfector, If, however,
sterilization is not feasible because the
instrument will be damaged by higher
heat exposure, the instruments may be
treated terminally in the G 7881 Dental
Thermal Disinfector. Semicritical
instruments do not penetrate soft
tissues or bone but contact oral tissues,
e.g. mirrors and amalgam placement
instruments.
Noncritical instuments may be treated
terminally in the G 7881 Dental Thermal
Disinfector. Noncritical instruments or
devices come into contact only with
intact skin, e.g. external components of
x-ray heads.
