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 patient's mouth, the lips,
cheek and tongue should be retracted to prevent
accidental contact with the activated tip.

For detailed information, contact your local DENTSPLY
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 scaler's 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 insert's 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.
Section 9: System Care

9.1 Daily Maintenance

It is recommended that you perform the following
maintenance procedures to help minimize bio-film
formation in the water path of your Cavitron BOBCAT Pro
ultrasonic scaler which could affect the water flow to the
ultrasonic insert, and scaling performance.
Start-Up Procedures at the beginning of the day:
1. Open the manual shut-off valve on the dental office
water supply system.
2. Turn the System ON using the ON/OFF control switch.
(See illustration on page 5). Verify the Power Indicator
Light is lit.
3. Set the Power Control knob to the minimum setting.
4. Set the Water Control knob to maximum.
5. Hold the Handpiece (without an insert installed) upright
over a sink or drain. Activate the Foot Control and flush
the water line for at least 2 minutes.
6. Place a sterilized insert into the Handpiece and set the
Water Control knob and Power Control knob to your
preferred operating position.
Between Patients:
1. Remove ultrasonic insert used, clean and sterilize.
2. Disinfect the surfaces of the cabinet, Power Cord,
Handpiece and cable assembly and Foot Control and
cable assembly by applying an approved non-immersion
type disinfectant solution* carefully following the
instructions provided by the disinfectant solution
manufacturer. To clean system, generously spray
disinfectant solution on a clean towel and wipe all
surfaces. Discard used towel. To disinfect system,
generously spray disinfectant on a clean towel and
wipe all surfaces. Allow disinfectant solution to air
dry. Never spray disinfectant solution directly on the
ultrasonic scaler.
3. Set the power to minimum and hold the handpiece over a
sink or drain and flush the water line at maximum water
flow for 30 seconds.
4. When ready, place a sterilized insert into the handpiece.
Shut-Down Procedures at the end of the day:
1. Remove ultrasonic insert used, clean and sterilize.
2. Turn the System OFF.
3. Disinfect the surfaces of the cabinet, Power Cord,
Handpiece and cable assembly and Foot Control and
cable assembly by applying an approved non-immersion
type disinfectant solution* carefully following the
instructions provided by the disinfectant solution
manufacturer. To clean system, generously spray
disinfectant solution on a clean towel and wipe all
surfaces. Discard used towel. To disinfect system,
generously spray disinfectant on a clean towel and
wipe all surfaces. Allow disinfectant solution to air
dry. Never spray disinfectant solution directly on the
ultrasonic scaler.
4. Close the manual shut-off valve on the dental water
supply system.
*NOTE: Water-based disinfectant solutions are preferred.
Some alcohol-based disinfectant solutions may be harmful
and may discolor plastic materials.

9.2 Weekly Maintenance

It is strongly recommended that this system be disinfected
by chemically flushing the waterlines with a 1:10 Sodium
Hypochlorite solution (NaOC1) at the end of each week.
This can be accomplished by connecting this device to
the Cavitron DualSelect Dispensing System or a number
of other devices available from your local distributors.
Where this device is connected to the Cavitron DualSelect
Dispensing System, please follow the DualSelect system's
Directions for Use manual. If connected to another device,
please follow those directions for use, keeping in mind that
a chemical flush should be performed at maximum water
flow for at least 30 seconds. The system should be left
undisturbed for 10 minutes but no more than 30 minutes
to allow the sodium hypochlorite solution to soak in the
lines. As a suggestion, it is recommended that a sign be
placed on the system stating that the SYSTEM IS BEING
DISINFECTED WITH A STRONG DISINFECTANT AND
SHOULD NOT BE USED. When ready, flush system with
clean water for at least 30 seconds or until sodium hypo-
chlorite odor disappears. ALL CHEMICALS MUST BE
FLUSHED FROM THE SYSTEM BEFORE IT IS READY
FOR PATIENT USE.
