"All sterilizers should be monitored
at least once a week with commercial preparations of spores intended
specifically for the type of sterilizer."

"The adequacy of sterilization
cycles should be verified by the periodic use of spore - testing
devices (e.g., weekly for most dental practices)."

“Proper functioning of
sterilization cycles should
be verified by the periodic use (at least weekly) of biological
indicators (i.e. spore tests). Heat sensitive
chemical indicators (e.g.
those that change color after exposure to heat) alone do not ensure
adequacy of a sterilization cycle but may be used on the outside of
each pack to identify packs that have been processed through the
heating cycle. A simple and inexpensive method to confirm heat
penetration to all instruments during each cycle is the use of a
chemical indicator inside and in the center of either a load of
unwrapped instruments or in each multiple instrument pack; this
procedure is recommended for use in all dental practices.
Instructions provided by the manufacturers of medical/dental
instruments and sterilization devices should be followed closely.”

Report (MMWR), 41(RR-8), 28 May 1993.
“Steam and low temperature sterilizers (e.g., hydrogen peroxide gas
plasma, peracetic acid) should be monitored at least weekly with the
appropriate commercial preparation of spores. If a sterilizer is
used frequently (e.g., several loads per day), daily use of
biological indicators allows earlier discovery of
equipment malfunctions or procedural
errors and thus minimizes the extent of patient surveillance and
product recall needed in the event of a positive biological
indicator. Each load should be monitored if it contains implantable
objects. If feasible, implantable items should not be used until
the results of spore tests are known to be negative.” See
