Other problem areas to check:
• Ensure the file barely goes through the terminus. A loose file will
give inaccurate readings.
• If the apex is larger than .40mm there might not be ample
constricture for accurate readings.
• Bone or periodontal ligament loss (indicated by a radiolucency on
the film) can cause inaccurate readings.
• If battery power is low, plug the unit into a wall outlet
• File or probe contact with a metal restoration will ground the
circuit and inaccurately indicate the apex.
• If the canal is too dry, introduce NaOCl to the apical 1/2 of the canal.
Vitality Scanner (VS) Mode Instructions
Numeric Display
Vitality response values range from 1 to 80. When the maximum value
of 80 is reached, your Numeric Display flashes until contact is broken.
Graphic Display
When a circuit is completed, a small horizontal bar will appear
under the Numeric Display until the circuit is broken. A vertical bar
corresponds to the numeric response value.
Satellite Display
The Satellite Display mimics your Graphic Display. The top LED segment
indicates a completed circuit.
Vitality Scanner Directions for Use
1. Grasping the Satellite Cord plug by its knurled section, line up the
red dots and gently push it into its receptacle at the front of the
unit. The cord may only be plugged in or removed by pulling the
knurled section of the plug.
2. Place the Patient Lead Cord connector into the Satellite Cord
receptacle.
3. Insert either the Standard or the Mini Crown Test Probe into the
Patient Lead Cord receptacle.
4. Power the unit by depressing the
5. Ensure the unit reads "vitality" in the upper right hand corner
confirming the unit is in Vitality Scanner mode. If not, press the
button to do so.
6. Adjust the rate of stimulus increase with the panel keys. This rate
can be re-adjusted during testing.
7. Place the lip clip on the patient's lip. Direct contact between the
mucosa and the lip clip must be made for proper function.
8. Dry the tooth to be tested.
9. Dip the probe tip into a small amount of gel toothpaste or topical
anesthetic and place it on the tooth. Do not contact the gingiva.
10. Upon contact, a small horizontal bar appears under the numerical
display and remains until contact is broken.
11. Maintain contact with the tooth until your patient perceives
a pulsating pressure, warmth, or tingling. A chart on normal
responses follows this section.
12. If contact is broken and re-established within 1 second, testing
continues without resetting. This feature avoids accidental resetting
if momentary loss of contact occurs. The unit resets after 1 second
of lost contact to aid rapid testing of multiple teeth.
Test Response
Normal test response ranges for vital teeth are:
Incisors 10-40
Bicuspids 20-50
Molars 30-70
These are not absolutes and will vary from patient to patient.
Vitality Scanner Usage Notes and Hints
• The unit automatically activates upon contact between probe and
tooth. This ensures the patient initially receives the lowest output.
• Begin testing on teeth adjacent to the subject tooth to provide a
comparative basis.
• The Mini Crown Probe allows access below the margin of a
porcelain crown.
• Lower resistance of metallic fillings produce readings considerably
lower than natural tooth material.

Vitality Scanner Troubleshooting
A false negative occurs when a vital tooth does not respond to the
maximum level of 80.
Causes include:
• Moisture on the surface of the tooth. False negatives can often be
avoided by drying the tested tooth
• Ametallic filling contacting periodontal tissue.
• Severe calcification of pulpal tissue.
• Immature apices.
• Severe trauma to the tooth.
• Other conditions resulting in degradation of neural response.
A false positive occurs when your patient perceives the stimulus on a
necrotic tooth.
Causes include:
• A patient sensing stimulation in an adjacent tooth in contact with
the subject tooth.
• A patient sensing a periodontal neural stimulus instead of a pulpal
nerve stimulus. The periodontal response is quite different than
a pulpal response. Compare the sensation perceived on a tooth
being vitality tested with the direct stimulation of periodontal
tissue prior to vitality testing.
Expected Life of Accessories
All accessories are reusable for a limited number of procedures.
This number is highly dependent on how and for what duration the
instrument is used and, therefore, will vary significantly from user to
user. If the device function appears erratic, an accessory may have
exceeded its useful life and should be replaced.
Cleaning, Sterilization, and Maintenance
Cleaning
The Unit and Satellite should be wiped twice with CaviWipes or a clean
cloth moistened with Cavicide (Metrex 714-516-7400) for cleaning and
disinfecting. The first wipe will clean the instrument, the second wipe
will disinfect. Do not submerge the device or allow liquid to enter the
enclosure. Do not Autoclave the unit or satellite.
Sterilization
Probes, File Clips, and the Patient Lead Cord must be cleaned, sterilized,
and inspected before every use:
1. Clean with CaviWipes or a clean cloth moistened with Cavicide or
warm water. Dry thoroughly.
2. Double wrap the Probes, Clips, and Lead Cords using a typical central
service wrapping technique and place into autoclave unit avoiding
contact with other instruments.
3. Operate sterilization cycle at 250°F (121°C) for 30 minutes or 270°F
(132°C) for 25 minutes. Follow the instructions supplied with your
autoclave unit for specific operating instructions.
