EPA-registered disinfectant. Also disinfect pliers and
other special instruments after each use, even if they do
not come in contact with blood or saliva. An alternate
method is immersing the instruments in an
EPA-registered intermediate or high-level disinfectant
such as iodophor or 2 percent glutaraldehyde.
The work authorization request will be closed out
in the Prosthetic Log by entering the date of
completion. This is done by the delivering dentist or
the technician. The work authorization request will be
retained in the laboratory for two years. The case pan
and its contents will be placed on the plaster bench for
cleaning. Cleaning includes the emptying of used
models and the spraying down of the case pan.
GUIDELINES FOR INFECTION
CONTROL IN THE DENTAL
When you are working in the prosthetic
department or the laboratory, infection control is still a
major concern. Follow BUMEDINST 6600.10, Dental
Infection Control Program, for complete guidance and
instructions. Prostheses or impressions may carry a
multitude of bacteria in dental plaque, blood, or saliva.
To protect everyone from cross contamination and
possible infection, dental personnel must use proper
techniques for disinfection of material before sending
it to the laboratory from the DTR and vice versa.
Place barriers wherever possible to prevent cross
contamination. Establish a designated area in the
dental laboratory where technicians disinfect all
incoming and outgoing items.
DTR INFECTION CONTROL
Wipe contaminated shade guides, face-bows,
a r t i c u l a t o r s , a n d a l c o h o l t o r c h e s w i t h a n
When possible, use trays to allow sterilization or
disinfection of multiple instruments.
Unit Dose Concept
Use of the unit dose concept prevents
contamination of bulk supplies. Dispense enough to
complete the entire procedure when using such items
as petroleum jelly, impression materials, waxes,
pressure disclosing or indicator paste, disposable
brushes, and orthodontic brackets and wires.
Processing and Transfer to the Laboratory
When possible, rinse and disinfect impressions,
prostheses, and intraoral devices before transfer to the
laboratory to reduce chances of cross contamination.
If the integrity of the item or material is compromised
by this disinfection, a waiver should be requested
through the command on the item (for example,
procelain-stained crown before bake). Place casts and
prostheses in self-sealing plastic bags to prevent
contact with adjacent materials, the shipping box,
foam insulation, or paper work. Consider everything
returned from a dental laboratory as contaminated.
The receiving facility must disinfect these items.
