8.2 patient positioning
For optimal access to both the upper and lower arches, the
backrest of the chair should be adjusted as for other dental
procedures. This assures patient comfort and clinician
visibility.
Have the patient turn his/her head to the right or left. Also
position chin up or down depending upon the quadrant and
surface being treated. Evacuate irrigant using either a saliva
ejector or High Volume Evacuator (HVE).
8.3 performing ultrasonic

Scaling procedures

Note: Refer to the Infection Control Information
booklet supplied with your system and Section 9 of
this manual for general procedures to be followed
at the beginning of each day and between patients.
• The edges of Cavitron Ultrasonic Inserts are intentionally
rounded so there is minimal danger of tissue laceration
with proper ultrasonic scaling technique. Whenever the
insert tip is placed in the patient's mouth, the lips,
cheek and tongue should be retracted to prevent
accidental (prolonged) contact with the activated tip.
• Turn Power Level Control to select ultrasonic power level
for operation. Clockwise increases system power.
Power level will increase throughout the full range of the
control. Hold the handpiece over a sink or drain.
Press the foot control to activate the system. Check
spray to verify fluid is reaching the working end of the
insert tip. Adjust the Lavage Control to ensure adequate
flow for the selected power setting. Greater flow settings
provide cooler irrigation.
• It may be necessary to adjust lavage with the system in
"Boost" mode (Foot Control fully depressed) so adequate
fluid will be available to cool tip to tooth interface.
• In general, it is suggested that a "feather-light-touch" be
used for ultrasonic scaling. The motion of the activated
tip and acoustic effects of the irrigating fluid, in most
cases, are adequate to remove even the most tenacious
calculus.
• Periodically check the Cavitron Ultrasonic Insert for wear
with the Cavitron Insert Efficiency Indicator.
• The use of a saliva ejector or High Volume Evacuator
(HVE) is recommended during all procedures.
• Set the system's Power Level Control to the lowest
efficient power setting for the application and the
selected insert.
8.4 patient Comfort Considerations
Reasons for sensitivity
• Incorrect tip placement. The point should never be
directed toward tooth root surfaces.
• Not keeping tip in motion on tooth. Do not allow the
insert to remain in a static position on any one area of
the tooth. Change the insert's path of motion.
• Applying excessive pressure. Use a very light grasp
and pressure, with a soft tissue fulcrum whenever
possible, especially on exposed cementum.
• If sensitivity persists, decrease power setting and/or
move from the sensitive tooth to another and then return.
SECTION 9: System Care
It is recommended that you perform the following maintenance
procedures.
9.1 daily maintenance
START-UP .PROCEDURES .AT .THE .
BEGInnInG .OF .THE .DAy:
1. Open the manual shut-off valve on the dental office
water supply system.
2. Install a sterilized Steri-Mate handpiece on the
handpiece cable.
3. Turn Main Power Switch to the ON (I) position. Verify
the ON/OFF indicator light is lit.
4. Set the Power Level Control to the minimum setting
(not rinse).
5. Set the Lavage Control on the handpiece cable to
maximum.
6. Hold the Handpiece (without an insert installed)
upright over a sink or drain. Activate the Purge
Control button.
• The Purge button will light for two minutes
indicating activation of the purge function.
• If the Purge button is activated with an insert
present in the handpiece, the button will blink for
3 seconds and disable. Remove the insert from
the handpiece and press the Purge button again.
• The Purge function can be interrupted at any time
by pressing the Purge button again or by
pressing the foot control.
7. After completing the purge cycle, place a sterilized
insert into the Handpiece and set the Ultrasonic
Power Level Control and Lavage Control to your
preferred operating position.
