Matrix bands
This is a convenient supplement to other
techniques but the coffer
dam effect provided by the encircling band can be useful in extreme
situations. The band must be well adapted and wedged to be effective
in this role.
Pharmacological
This group of agents may have systemic
medical implications and are
very rarely used in routine practice.
Astringent solutions
These may be applied to control gingival haemorrhage but may cause
gingival trauma,
if not used with care, as many are caustic or have a
low pH.
Adrenaline
One in one thousand adrenaline solution may be applied topically for
a short period (up to 2 min) on a cotton pellet
to control local gingival
bleeding.
Antisialogogues
Antisialogogues, drugs that inhibit oral secretions, appear in all
lists of moisture control techniques. However,
the use of such drugs
is extremely rarely indicated and is generally unsuitable for the
ambulant outpatient situation.
Hypnosis
This technique has been suggested for controlling patients’ salivary
flow rate.
