Section 8: Techniques for Use

8.1 Patient Positioning

• For optimal access to both the upper and lower arches,
the backrest of the chair should be adjusted to a 45˚
degree angle. 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 inten-
tionally rounded so there is little danger of tissue lacera-
tion with proper ultrasonic scaling technique. Whenever
the insert tip is placed in the patientʼs mouth, the lips,
cheek and tongue should be retracted to prevent
accidental contact with the activated tip.

representative or authorized DENSTPLYdistributor.
• 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 work
ing end of the insert tip). Adjust the Water Control knob
to ensure adequate flow. Greater flow settings provide
cooler irrigant.
• 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 water, in most cases, is
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 ultrasonic scalerʼs Power Control knob to the
lowest effective 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 insertʼs 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.
