"feeling" or "discomfort" are always prefera-
ble to the word "pain".
• Standard infection control protocol must be
followed by the operator during pulp test-
ing, by wearing disposable rubber, vinyl or
nitrile gloves.
• The tooth to be tested and the adjacent teeth
must be clean and dry. Interproximal embra-
sures should be made free of any impacted
food debris, saliva, water or plaque by floss-
ing, scaling with an instrument and air-drying
before testing.
• Electrically isolate the tooth being test-
ed from neighboring teeth or metallic res-
torations by wrapping it with a clear mylar
strip, such as those used in fabricating Class
3 composite restorations.
• A dry cotton roll should be placed in the buc-
cal vestibule to isolate the tooth from the lip
and cheek.
• A plastic mirror should be used to keep the
tongue off the tooth during testing.
• There are two alternatives for completing the
circuit using the autoclavable Ground Clip and
lead wire.
1. Method 1: Over the Lip
• Plug one end of the wire into the socket
on the bottom of the Power Unit (Figure 9)
and insert the Ground Clip (Figure 10) into
the socket at the other end of the wire.
• Place a small amount of toothpaste on
the patient's lip (to enhance electrical
conductivity), then place the Ground Clip
over the patient's toothpaste-coated lip
and confirm there is good contact be-
tween the lip and the clip.
2. Method 2: Finger Hold
• Connect the wire and Ground Clip to the
Power Unit as per Method 1.
• Place a small amount of toothpaste on
the Ground Clip and have the patient se-
curely hold the metal clip between the
thumb and forefinger of either hand.

expect during the test and why the test is being
performed. Tell the patient that when the vitali-
ty test is underway, they should indicate, either
verbally or by carefully raising their hand (for
test utilizing the "Finger Hold" of the Ground
Clip, they should raise their free hand), at the
first sign of an awareness of the stimulus in
the tooth. As soon as they make you aware,
you will stop the test by releasing pressure on
the button and removing the probe from con-
tact with the tooth surface.
the option of giving the patient some control
over the testing procedure. This is done by tell-
ing the patient they can make the sensation in
the tooth stop if they let go of the Ground Clip.
Letting go of the Ground Clip will not turn off
the Digitest 3 and will not stop the numbers
on the digital screen from continuing to count
higher. It will only stop the patient from feel-
ing the stimulus.
on a limited basis, and only to patients who
may be hesitant to undergo the procedure due
to concerns of feeling extreme discomfort.
Patients offered the "Drop Clip" alternative
may anticipate discomfort and drop the clip
prematurely, thereby compromising the ac-
curacy of the test results.

touch points for the Tooth Probes. Teeth se-
lected for pulp testing must possess enough
exposed enamel or dentin to allow the probe
to make contact without touching the gin-
giva or a metal restoration. In certain cas-
es, this may require the use of a Precision
Probe (included).
