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). Withdraw 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 analgesia. 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 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
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
autoclavable Ground Clip and Wire
Assembly. Plug one end of the wire assembly
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).
