Section 7: Accessories
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 as for other
dental procedures. This assures patient comfort and
clinician visibility.
7.1 Accessories List*
1. AC Power Cord Set
2. Cavitron
®
Ultrasonic Inserts
3. Cavitron™ Jet Insert Nozzle
4. Dual position Foot Switch Assembly
5. DualSelect
™
Medicament Dispensing System
6. JetShield™ Aerosol Reduction Device
*For detailed information, contact your local DENTSPLY
®
Representative.
• Have the patient turn their head to the right or left. Also
position their chin up or down depending upon the
quadrant and surface being treated. Evacuate irrigant
using either a saliva ejector or HVE.
8.2 Performing Ultrasonic Scaling
Procedures
NOTE: Refer to the Infection Control Information card (Form
no. 80722) supplied with your Unit for general procedures to be
followed at the beginning of each day and between patients.
• The edges of Cavitron
®
Ultrasonic Inserts are intention-
ally rounded so there is little danger of tissue laceration
with proper ultrasonic scaling technique. Whenever the
insert tip is placed within the patient’s mouth, the lips,
cheek and tongue should be retracted to prevent acciden-
tal prolonged contact with the activated tip.
• Hold the empty Handpiece in an upright position and
activate the Foot Control until fluid 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.
• Set the Unit’s Power Adjustment knob to the lowest
power setting for the application and the selected insert.
• Activate the Foot Control and hold the Handpiece over a
sink or drain. Check spray temperature to verify fluid is
reaching the working end of the insert tip. Adjust the
Lavage flow knob to ensure adequate flow for the
selected Power setting. Greater flow settings provide
cooler irrigant.
• 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 both supra- and subgingivally. The motion of the
activated tip and acoustic effects in the irrigating fluid, in
most cases, is adequate to remove even the most
tenacious calculus.
• Use Cavitron
®
efficiency indicator if an insert seems to
require increased finger pressure to function adequately.
• The use of a saliva ejector or HVE is recommended
during all procedures.
8.3 Patient Comfort Considerations
Reasons for sensitivity
1. Incorrect tip placement. Point should be directed away
from root surfaces.
2. 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.
3. Applying pressure. Use extremely light grasp and
pressure, especially on exposed cementum.
4. If sensitivity persists, decrease power setting and/or
move from the sensitive tooth to another and then
return.
