• Discard and replace any Tooth Probe if the metal
or the insulation becomes damaged during use.
INSTALLING / REPLACING
THE BATTERY
• The Digitest 3 Pulp Vitality Tester comes with a
high-output, 9-Volt alkaline battery.
• To install the battery, remove screw (Figure 3) and
carefully lift off the plastic battery door by gently
pulling it away from the Power Unit (Figure 4). With-
draw the old battery from the battery enclosure, and
unsnap it from the wire battery connector (Figure 5).
Discard in accordance with applicable laws.
• The fresh battery should be snapped onto the
connector and placed in the Power Unit so the
top end attached to the connector is placed into
the opening first (Figure 6). Slight pressure on
the bottom of the battery will help it to slide home
(Figure 7). Replace the plastic battery door by
engaging the tabs on the bottom first (Figure 8),
and tighten the screw gently (Figure 9).
• The replacement battery may be a Duracell
MN1604, Panasonic
Although rechargeable 9-Volt batteries may be
utilized, they will require more frequent charging
because of the considerable voltage required to
perform the pulp testing procedure.
DIGITEST 3 SETUP PRIOR TO
PERFORMING PULP VITALITY TESTING
• To accurately diagnose the condition of the tooth,
pulp testing must be performed on a patient who
has not received local anaesthesia or gas anal-
gesia. Make sure to use the Digitest 3 BEFORE
you perform these procedures.
• Fully explain to the patient what you will be doing
prior to the pulp test, so they are not surprised during
the test. Using the words "feeling" or "discomfort" are
always preferable to the word "pain".
• Standard infection control protocol must be
followed by the operator during pulp testing, by
wearing disposable rubber, vinyl or nitrile gloves.

• The tooth to be tested and the adjacent teeth
must be clean and dry. Interproximal embrasures
should be made free of any impacted food debris,
saliva, water or plaque by flossing, scaling with an
instrument and air-drying before testing.
• Electrically isolate the tooth being tested from
neighboring teeth or metallic restorations by wrap-
ping 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 buccal
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.
• The circuit is completed by using the autoclav-
able Ground Clip and Lead Wire. Plug one end
of the Lead Wire into the socket on the bottom of
the Power Unit (Figure 10), and insert the Ground
Clip into the other socket (Figure 11).
• Place a small amount of toothpaste on the Ground
Clip and ask the patient to hold the metal of the
clip between their right thumb and forefinger.
Then ask them to hold the black plastic wire
socket between their left thumb and forefinger
(Figure 12).
• Explain to the patient that the test should not hurt,
but that they are in control, and that they can stop
it at any time. Tell them that when they first feel
a change in the tooth being tested, such as puls-
ing, buzzing, tingling or slight discomfort, all they
need to do is let go of the metal Ground Clip and
the test will be over.
