Introduction
DENTSPLY Professional is an ISO 13485 registered company.
The DENTSPLY Cavitron® SPS™ Scaler System is recognized by
Underwriters Laboratories Inc. with respect to electric shock, fire,
and mechanical hazards in accordance with UL 60601-1 and CSA
C22.2 no. 601.1.
The Cavitron SPS Ultrasonic Scaler is equipped with a Sustained
Performance System™ (SPS), which offers a constant balance
between scaling efficiency and patient comfort by maintaining the
unit's power level when the insert tip encounters tenacious deposits
allowing the clinician to effectively scale even at a decreased/lower
power setting.
The System operates by converting an SELV source current into
high frequency current. The ultrasonic system consists of two
parts: an insert and the SPS™ electronic system. The SPS™ system
incorporates two closed loops. One loop provides automatic tuning
(operating frequency is adjusted to be at resonance for each insert),
the second loop automatically controls the tip stroke over different
working conditions. The DENTSPLY Cavitron® SPS™ scaler
produces 30,000 microscopically small strokes per second at the
insert’s working tip. This, combined with acoustic effects of the
coolant water, produces a synergistic action that literally “powers
away” the heaviest calculus deposits while providing exceptional
operator and patient comfort.

• It is the responsibility of the Dental Healthcare Professional to
determine the appropriate uses of this product and to understand:
• the health of each patient,
• the dental procedures being undertaken,
• and applicable industry and governmental agency
recommendations for infection control in dental
healthcare settings,
• requirements, and regulations for safe practice of
dentistry; and
• these Directions for Use in their entirety, including
Section 4 Precautions, Section 5 Infection Control, and
Section 10 System Care.
• This product is designed to assist in eliminating susceptibility
to retraction of oral fluids. To ensure adequate protection
from cross-contamination from other devices connected to the
Dental Unit, it is highly recommended that the Dental Unit be
installed with anti-retraction features. Additionally, the Dental
Unit, including the anti-retraction features, must be properly
maintained and periodically tested. For more information,
please contact your Dental Unit manufacturer.
• Where asepsis is required or deemed appropriate in the best
professional judgment of the Dental Healthcare Professional,
this product should not be used, unless used in combination with
a Sterile Lavage Kit, (P/N 81340).
• During boil-water advisories, this product should not be operated
as an open water system (e.g. connected to a public water
system). Dental Healthcare Professionals should discontinue use
on patients and contact the local water authority to determine
when it is safe to continue use of this product. When the
advisory is cancelled, the local water authority should provide
guidance for flushing of waterlines. All incoming waterlines
from the public water system inside the dental office (e.g.,
faucets, waterlines, and dental equipment) should be flushed in
accordance with manufacturer’s instructions for a minimum of
5 minutes.
• Prior to beginning treatment, patients should rinse with a known
antimicrobial such as Chlorhexidine Gluconate 0.12%. Rinsing
with an antimicrobial reduces the chance of infection and
reduces the number of microorganisms released in the form of
aerosols during treatment.
• The use of High Volume Saliva Evacuation to reduce the
quantity of aerosols released during treatment is highly
recommended.
• Failure to follow recommendations for environmental operating
conditions, including input water temperature, could result in
injury to patients or users.

ENGLISH • 5
Efficiency Indicator is enclosed for your use.
• If excessive wear is noted, or the insert has been bent, reshaped or
otherwise damaged, discard the insert immediately.
• Ultrasonic insert tips that have been bent, damaged, or reshaped are
susceptible to in-use breakage and should be discarded and replaced
immediately.
• Retract the lips, cheeks, and tongue to prevent contact with the insert tip
whenever it is placed in the patient’s mouth.
• Water should be used for all scaling procedures. Water flow is adjustable
from less than 10 to greater than 60 ml per minute.
• Only adjust the systems’s power adjustment knob with the insert outside
the patients mouth.
Section 4: Precautions
4.1 System Precautions
• Equipment flushing and dental water supply system
maintenance are strongly recommended. See Section 10:
System Care.
• Close manual shut-off valve on the dental office water supply
every night before leaving the office.
• The use of an in-line water filter is recommended.
• Never operate system without fluid flowing through handpiece.
• Always ensure that the electrical connections on the handpiece
cable and the Steri-Mate® Handpiece are clean and dry before
assembling them for use.
4.2 Procedural Precautions
• The Cavitron SPS G90 unit works with Cavitron inserts as a system,
and was designed and tested to deliver maximum performance for all
currently available Cavitron and Cavitron Bellissima® brand ultrasonic
inserts. Companies that manufacture, repair or modify inserts carry the
sole responsibility for proving the efficacy and performance of their
products when used as a part of this system. Users are cautioned to
understand the operating limits of their inserts before using in a clinical
setting.
• Like bristles of a toothbrush, ultrasonic insert tips “wear” with
use. Inserts with just 2 mm of wear lose about 50% of their scaling
efficiency. In general, it is recommended that ultrasonic inserts be
discarded and replaced after one year of use to maintain optimal
efficiency and avoid breakage. A DENTSPLY Professional Insert

Section 5: Infection Control
5.1 General Information
• As with all dental procedures, use universal precautions (i.e., wear
face mask, eyewear, or face shield, gloves, and protective gown).
• For operator and patient safety, carefully practice the
infection control procedures detailed in the Infection Control
Information Booklet accompanying your System. Additional
booklets can be obtained by calling Customer Service at
1-800-989-8826, Monday through Friday, 8:00 A.M. to 5:00 P.M.
(Eastern Time). For areas outside the U.S., contact your local
DENTSPLY Professional representative.
• As with high speed handpieces and other dental devices, the
combination of water and ultrasonic vibration from the Cavitron SPS
Scaler will create aerosols. Following the procedural guidelines in
Section 9 of this manual can effectively control and minimize aerosol
dispersion.
5.2 Water Supply Recommendations
• It is highly recommended that all dental water supply systems
conform to applicable CDC (Centers for Disease Control and
Prevention) and ADA (American Dental Association) standards,
and that all recommendations be followed in terms of flushing, and
general infection control procedures. (See Sections 6.2 and 10)
Knowledge of and compliance with agency guidelines, standards and
recommendations is the sole responsibility of the Dental Healthcare
Professional.
• As a medical device, Cavitron® products need to be installed
in accordance with local or national regulations, including guidelines
for water quality (e.g. drinking water). As an open water system,
such regulation may require your Cavitron product to be connected
to a centralized water control device that prevents water containing
contaminates from back-flow into the water supply.

accidental prolonged contact with the activated tip
whenever the insert is placed in the mouth.
• Always adjust the lavage so adequate fluid will be
available to cool the 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 of the irrigating fluid,
in most cases, is adequate to remove even the most
tenacious calculus.
• Set the System’s power adjustment knob to the lowest
power setting for the application and the selected insert.
• Only adjust the System’s power adjustment knob with
the insert outside the patients mouth.
9.3 Patient Comfort Considerations
Reasons for sensitivity
• Incorrect tip placement. Point should be directed away
from root surfaces.
• Not keeping the tip in motion on the 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 pressure. Use extremely light grasp and
pressure, especially on exposed cementum.
