9.5 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.

10. System Care

It is recommended that you perform the following maintenance
procedures.

10.1 Daily Maintenance

Start-Up Procedures at the beginning of the day:
1. Open the manual shut-off valve on the dental office water
supply system.
2. Install a sterilized Steri-Mate Handpiece onto the handpiece cable.
3. Set the Power Level Control to minimum and the Lavage
Control to maximum.
4. Turn the system ON.
5. Hold the sterilized handpiece (without insert installed) over a sink
or drain. Activate the Purge Mode by pressing the Purge icon.
• The Purge screen will appear indicating proper activation
of the purge function. Time icon will count down indicating
completion of purge cycle.
• The Purge function can be interrupted at any time during
the two minute cycle by pressing the Scale icon or by
pressing the Foot Pedal.
6. After completing the purge cycle, place a sterilized 30kHz
Cavitron Ultrasonic Insert into the handpiece and set the
Power Level Control and Lavage Control to your preferred
operating position for ultrasonic scaling.
Between Patients:
1. Remove the used Cavitron Ultrasonic Insert. Clean and sterilize
following the Infection Control Procedures that were enclosed
with your insert.
2. Hold the handpiece over a sink or drain and activate Purge
function as described in Step 5 of the Start-Up procedure.
3. After the Purge cycle is complete, turn the System to the OFF
(0) position.
4. Remove the Steri-Mate handpiece, clean and sterilize following
the procedures outlined in the Cavitron Systems Infection
Control Procedures booklet that was enclosed with your system.
5. Before disinfecting surface of cabinet, lock the touch
screen by pressing the Lock icon. Disinfect the surfaces of
the cabinet, Power Cord, Handpiece Cable, Tap-On Foot
Pedal and Cable assembly (if applicable), Water Supply
lines as instructed in the Cavitron Systems Infection Control
Procedures booklet. DO NOT SPRAY DISINFECTANT
SOLUTION DIRECTLY ON SYSTEM SURFACES*.
6. Inspect the handpiece cable for any breaks or tears.
7. If using a closed water supply or DualSelect Dispensing
System, check for adequate fluid volumes for the next patient.
8. When ready to use, press the unlock icon, place a sterilized
Steri-Mate Handpiece onto the handpiece cable assembly
and insert a sterilized ultrasonic insert into the handpiece and
adjust system controls as preferred.
Shut-Down Procedures at the end of the day:
Follow the "Between Patients" maintenance procedures, Steps
1 through 6. In addition, it is recommended to close the manual
shut-off valve on the dental water supply system.
*NOTE: Broad spectrum hospital grade water-based disinfection
solutions are preferred, such as Lysol IC. Some alcohol-based
disinfectant solutions may be harmful and may discolor plastic
materials.

10.2 Weekly Maintenance

It is strongly recommended that this system be disinfected
by chemically flushing the waterlines with a 1:10 Sodium
Hypochlorite solution (NaOCl) 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 hypochlorite odor disappears. ALL CHEMICALS
MUST BE FLUSHED FROM THE SYSTEM BEFORE IT IS READY
FOR PATIENT USE.

10.3 Monthly Maintenance

Water Line Filter Maintenance:
When the water line filter becomes discolored or the filter icon
illuminates, the filter should be replaced to prevent reduced water
flow to the Cavitron system.
1. Verify that the system is turned OFF.
2. Disconnect the water supply hose from the dental office water
supply. If a quick disconnect connector is attached to the end
of the hose, relieve the water pressure by pressing the tip of
the connector in an appropriate container and drain the water.
3. Grasp the fittings on either side of the filter disk and twist
counterclockwise. Remove the filter section from either side of
the water hose.
4. Install the replacement filter onto the water hose fittings. The
filter should be positioned to match up with the correct hose
fitting.
5. Hand tighten one hose fitting onto filter in a clockwise
direction. Tighten second hose onto filter in clockwise
direction. Reconnect the water supply line, operate unit to
bleed the air and test for leaks.
6. Turn the unit back ON, press and hold filter icon until it
disappears to reset filter maintenance icon.

Although service and repair of the Cavitron
following are some basic troubleshooting procedures that will help avoid unnecessary service calls. Generally, check all lines and
connections to and from the System. A loose plug or connection will often create problems. Check the settings on the System's controls.
