SNOOP
is a propylene glycol based caries detector used for
indentifying infected carious dentin. Its dark blue
color contrasts with dentin and is easily distinguished
from the pulp.
Carious
dentin is made up of two distinct layers. There is an
outer layer of infected carious dentin which is soft,
discolored, nonvital, nonsensitive and cannot remineralize.
This outer layer is stained by a 10 second application
of SNOOP and should be
removed. There is also an inner layer of uninfected
carious dentin (also referred to as "affected" dentin)
which is vital and sensitive, not infused with bacteria,
and may be somewhat softened and demineralized, but
which is capable of remineralizing. This inner layer
is not stained by a 10 second application of SNOOP
, and it should not be removed.
Research
indicates that the dye in the caries detector bonds
to the denatured collagen which is present in the outer
infected dentin but which is not present in the inner
uninfected dentin and normal dentin. Only the outer
infected dentin is stained. As a result, SNOOP
distinguishes between these two layers and enables the
dentist to perform a conservative cavity preparation
removing only the outer infected dentin.
