Priming the Handpiece
1.
Confirm the unit is ON and that the green LED on the front
panel is illuminated.
2.
Attach an autoclaved handpiece to the handpiece cable that has
already been purged. Make sure there is no insert connected into
the handpiece. (Purging the waterlines can only be accomplished
when the handpiece is not connected to the cable.)
3.
Hold the handpiece in an upright position.
4.
Depress the foot pedal.
5.
Water will begin to flow and fill the handpiece. Priming of the
handpiece should be done with a water setting between
medium and maximum flow. (The lower the setting the
longer it will take to prime and fill the handpiece with water.)
6.
To stop water flow into the handpiece, remove foot from
foot pedal.
7.
An insert may now be placed into the handpiece for scaling.
Clinical Suggestions
on Tooth Scaling
• To prevent any potential injury to the patient, ultrasonic scalers
should be used by trained, dental professionals only.
• Protect patient’s eyes, lips, cheek, tongue or other vulnerable
soft tissues when using this device. Inadvertent contact with
Insert tip may cause a slight burn.
• Inserts and detachable handpiece must be sterilized before
each use.
• Use of a face mask by the clinician, and high-volume intraoral
suction, is strongly recommended when operating this device to
avoid inhalation of contaminated aerosols.
• To prevent a possible slight burn to the patient or clinician,
NEVER OPERATE UNIT WITHOUT WATER FLOWING.
• Use the lowest effective scaling power for the case at hand. This
keeps heat generation to a minimum.
• Before using the insert in the oral cavity, adjust the water spray
following the graphics on the faceplate of the scaler over a sink
or cuspidor until desired mist is obtained. Good water flow will
act as a coolant and aid in flushing out debris to maximize
patient comfort.
• If patient is new to ultrasonic scaling, explain to them what to
expect. Usually, the patient should not experience discomfort. If
patient experiences uncomfortable heat, adjust power and
water controls accordingly.
• Do not test a scaler tip for vibration on your fingers while the
unit is operating. This is not a valid test of how scaling feels to
the patient.
• Hold the handpiece in a comfortable pen-grasp. To remove
deposits from teeth, always use a light brushing stroke with the
side of the insert tip, in contact with and parallel to the root surface.
Excess pressure will not improve scaling action but may cause
heating and pain to the patient. Keep the scaler insert in motion,
using repeated gentle strokes to remove all tenacious deposits.
• If the patient experiences discomfort due to the sound and
vibration from the Scaling procedure, provide ear protection.
• Do not use the point of the insert on the tooth surface. You may
gouge the tooth.
• Pause occasionally during scaling by removing foot from pedal
to evaluate deposit removal.
• Exercise caution near ceramic restorations, as they can discolor
or fracture if stressed.
Common Operator Errors that May
Result in Poor Clinical Performance
• Failure to keep insert tip parallel to the long axis of the tooth.
• Excessive use of hand pressure.
• Failure to use the lowest effective power setting for the case
at hand.
• Insufficient water flow.
• Scaling with the point of the insert instead of the side.
• Inserts that are damaged, bent or worn out.
Cleaning and Infection Control
• Consult www.CDC.gov for the “Guidelines for Infection Control in
Dental Health - Care Settings” and “Statement on Reprocessing
Dental Handpieces”.
• DO NOT AUTOCLAVE the Turb control unit, as
autoclave heat will destroy it. The control unit should be cleaned
of debris with a water-damp paper towel, disinfected by wiping
with a paper towel that has been saturated with an EPA-
registered low-level (HIV/HBV claim) to intermediate-level
(tuberculocidal claim) hospital disinfectant, wiped of chemical
residue with a water- damp paper towel, and dried. Utilize the
surface disinfecting protocol of the disinfectant manufacturer.
• Autoclaving does not remove debris that has accumulated on
the handpiece or the insert. Failure to adequately remove debris
will result in inadequate sterilization. Rinse the handpiece, and
the insert under warm running water for 30 seconds to remove
any external or internal soil or debris. Using a soft soapy cleaning
brush to assist in the cleaning, if necessary. Use non-ammoniated
detergent or dishwashing soap. Do not use ammoniated
cleansers or disinfectants. Rinse the devices again under warm
running water for 30 seconds to remove any residual soap and
blot dry with a dry lint-free towel. Wipe Insert with a lint free
towel that has been saturated in an EPA-approved, hospital-
grade intermediate or high-level disinfectant (minimum 2.5%
Glutaraldehyde solution), following the instructions for use
provided by the disinfectant manufacturer. Dry the devices with
a dry lint-free towel.
• The handpiece and inserts may be sterilized in any conventional
steam autoclave following manufacturer’s instructions. A
typical steam sterilization cycle is 132 +/- 2°C for 4 mins.
(Vacuum) or 132 +/- 2°C for 15 mins. (Gravity), followed by a
15-minute minimum cool-down period. Use a steam sterilization
pouch that is compliant with ISO 1140-1 Type 4 and 11607
standards. Once items are sterilized, adhere to the shelf-life
specified by the pouch manufacturer. After sterilization, inspect
the device in the autoclave bag for integrity. If suspicion about
the item exists, discard it and order a replacement from Parkell
or your dealer.
• DO NOT USE DRY HEAT OR CHEMCLAVE on the handpiece or
the insert.
• The handpieces are designed to withstand a minimum of 1,000
autoclaving cycles when reprocessed.
• The ultrasonic inserts from Parkell are designed to withstand a
minimum of 500 autoclaving cycles when reprocessed.
