Section 8: Techniques for Use
8.1 Patient Positioning
(Picture)
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).
8.2 Performing Ultrasonic Scaling Procedures
• Note: Refer to the Infection Control Information Booklet supplied with your system 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 little 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.
• Hold the empty Handpiece in an upright position over a sink or drain. Activate the Foot Control until
water exits.
• Lubricate the rubber O-ring on the insert with water before placing it into the handpiece. Fully seat
insert with a gentle push-twist motion. DO NOT FORCE.
• Activate the System. Hold the handpiece over a sink or drain. (Check spray to verify fluid is reaching
the working end of the insert tip). Adjust the water 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 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 Ultrasonic Power Control knob to the lowest efficient power setting for the
application and the selected insert.
8.3 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.
