Section 10: System Care
10.1 Daily Protocol
Start-up procedures at the beginning of the day
1. Switch ON the dental treatment unit (refer to instruction manual
of treatment unit).
2. Remove the DENTSPLY Cavitron
®
cable connector assembly
from handpiece holder and set power adjustment to 30% of
maximum.
3. Connect Steri-Mate
®
handpiece to the cable connector assembly
(refer to the Infection Control information booklet for sterilizing
instructions).
4. Adjust the lavage control to maximum.
5. Hold the handpiece (without an insert installed) over a sink
or drain. Activate the foot control and flush water through
handpiece for at least two minutes.
6.
Place a sterilized insert into the handpiece using a gentle push-
twist motion. Refer to the Cavitron Ultrasonic Inserts Directions
for Use for cleaning and sterilizing instructions.
7. Activate the ultrasonics and adjust the power and lavage control
to your preferred operating positions.
accidental prolonged contact with the activated tip
whenever the insert is placed in the mouth.
• Always adjust the lavage so adequate fluid will be
available to cool the tip-tooth interface.
• In general, it is suggested that a “feather light touch” be
used both supra- and subgingivally. The motion of the
activated tip and acoustic effects of the irrigating fluid,
in most cases, is adequate to remove even the most
tenacious calculus.
• Set the System’s power adjustment knob to the lowest
power setting for the application and the selected insert.
• Only adjust the System’s power adjustment knob with
the insert outside the patients mouth.
9.3 Patient Comfort Considerations
Reasons for sensitivity
• Incorrect tip placement. Point should be directed away
from root surfaces.
• Not keeping the tip in motion on the 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 pressure. Use extremely light grasp and
pressure, especially on exposed cementum.
