a disinfecting solution, allow them to soak, and then
scrub them under water to avoid generating splatter.
You are still in the processing area of the CSR and
have just finished cleaning your instruments using one
of the three methods of cleaning discussed previously
and letting them dry as shown in figure 10-5. Perform
the following procedures in the sterilization process
Inspection and Sorting of
After drying, you must inspect items closely for
wear, breakage, and cleanliness. Sort instruments
according to sets or packs. This is the prestaging area
where your instruments are sorted before wrapping
Wrapping and Packaging
Wrapping and packaging is the last step just before
the sterilization process. Many different types of
sterilizers, packaging, and wrapping materials are used
in the CSR.
Before terminal (final) sterilization, wrap or
package all critical and semicritical items individually
or in sets. Ensure you place consumable supplies (fig.
10-6) that are required by your command in each
particular pack before wrapping such items as needles,
cotton rolls and pellets, gauze, aluminum foil for
dental light handles, internal indicators, and towels.
Dental instruments are usually placed in packs, on
trays or cassettes, before placing them into the
sterilizer. The most common wrapping materials and
containers are paper, paper/plastic, nylon tubing, and
cloth. Aluminum foil, closed metal trays, and
perforated cassettes may also be used. The packaging
or wrapping materials that you select depends on the
compatibility of what type of sterilization method you
are using. Table 10-1 shows various sterilization
packaging materials and their suitability to withstand
steam or dry heat sterilization. Always refer to the
sterilizer manufacturers instructions for suitability.
Paper materials are available in the form of bags or
flat disposable wraps.
Both types are sealed with
adhesive indicator tape. The combination paper/
plastic peel packs (fig. 10-7) are available in varied
sizes of preformed bags or rolls of varied widths that
can be cut to the desired length. Either type can be
sealed with the adhesive indicator tape or self-sealed.
Heat sealed plastic or nylon tubing should only be
used as an overwrap after the pack has been sterilized.
Heat sealed overwrapping will extend a 30 day shelf
life to 180 days.
