Patient Positioning; Performing Ultrasonic Scaling Procedures; Techniques For Use; Patient Comfort Considerations - DENTSPLY Cavitron Instrucciones Para El Uso

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.
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 booklet
supplied with your Unit for general procedures to be followed
at the beginning of each day and between patients.
• The edges of Cavitron
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.

• 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.

8.4 Air Polishing Powder Chamber

• Use only Cavitron
JET Combination System. Any other substances or
additives may clog the Unit and will void the warranty.
For your convenience, the Prophy powders are supplied
in bottles. Keep stored in a location that does not
exceed 95° F.
• A special container is provided with your System for use
in filling and emptying the powder chamber.
• It is strongly recommended that the Powder Chamber
be emptied at the end of each day. This will reduce
moisture absorption and minimize clogging.
To fill, or refill, the powder chamber:
• Turn the Unit OFF.
• Unscrew the Powder Fill Cap.
• With cap of powder bottle closed, shake the powder
bottle vigorously to break up any lumps that may have
formed from settling. Carefully pour powder into the
chamber until the level reaches the top of the center tube.
• Replace the Powder Chamber Cap and tighten.
• Turn the Unit ON.
NOTE: Use only Cavitron ® Prophy Powders in the unit.
Powder should be kept dry and stored in a location that does not
exceed 95° F.
