Ultrasonic Scaler G98A Installation and Service Manual
Please read carefully and completely before operating unit.
FORWARD DENTSPLY® Professional is an ISO13485 registered company. The DENTSPLY® Cavitron® SPS™ Scaler System is classified 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: the handpiece/insert combination 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.

•
Only adjust the system’s power adjustment knob with the insert outside the patients mouth.
Section 4: Infection Control
Section 3: Precautions
4.1 Infection Control Information Reference Booklet •
3.1 System Precautions •
Equipment flushing and dental water supply system maintenance are strongly recommended.
•
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.
4.2 General Infection Control Information
3.2 Precautions for Ultrasonic Prophylaxis Procedures •
Like a toothbrush, ultrasonic inserts “wear out” 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 90 days, under normal use, to maintain optimal efficiency and avoid breakage. A Cavitron® Insert Efficiency Indicator is enclosed for your use.
•
Discard the insert immediately if excessive wear is noted, or the insert shows signs of damage through mishandling.
•
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.
For your convenience, an Infection Control Information Reference Booklet has been included with your Cavitron® SPS™ System. Additional booklets can be obtained by calling Customer Service at 1-800-989-8826 or 717-767-8502 Monday through Friday, 8:00 AM to 5:00 PM (Eastern Time). For other areas, contact your local DENTSPLY representative. Insert sterilization information is included in each insert package.
•
Use standard personal protection equipment (i.e., wear face mask, eyewear, or face shield, gloves and protective gown).
•
For maximum operator and patient safety, carefully follow the Infection Control Information procedures detailed on the reference cards accompanying your System.
•
The combination of water and ultrasonic vibration will create aerosols. With proper technique, much of the aerosols can be effectively controlled and minimized. Please carefully follow the procedural guidelines regarding the use of your System.
4.3 Water Supply Recommendations •
6
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. Knowledge
of and compliance with agency guidelines, standards and recommendations is the sole responsibility of the Dental Healthcare Professional. •
2. Remove the cover of the Dental Control Unit. 3. Remove the mounting template from this manual and cut out as described (there are two templates).
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.
4. Place the template on the bottom of the Dental Control Unit and position to mark the mounting holes. 5. Check to be sure the Cavitron module will be properly placed and that the power control is easily accessible. 6. Carefully mark and drill the mounting holes.

Water Line Requirements
•
•
•
•
Incoming water supply line pressure to the ultrasonic scaler must be 25 psi (172kPa) minimum to 60 psi (414 kPa) maximum. If your dental water system's supply line pressure is above 60 psi, install a water pressure regulator on the water supply line to your Ultrasonic Scaler.
9. Secure all fittings with the supplied tubing retainers. 10. Secure the other end of the adapter assembly to the yellow tubing from the Cavitron module cable.
A manual shut-off valve on the dental water system supply line should be used so that the water can be completely shut-off when the office is unoccupied.
11. Secure the air line from the handpiece holder valve to the remaining barb on the adapter assembly.
A filter in the dental water system supply line is recommended so that the particles in the water supply will be trapped before reaching the ultrasonic scaler.
12. Locate the input water line in the Dental Control Unit. Cut the line and insert and secure a small tee fitting.
After the above installations are complete on the dental water supply system, the dental office water line should be thoroughly flushed prior to connection to the ultrasonic system.
13. Connect and secure the red tubing from the module cable to the remaining barb on the small tee fitting. 14. Locate the input drive air line in the Dental Control Unit. Cut line, insert and secure the large tee fitting.

•
Cavitron® Ultrasonic Inserts
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 irrigating fluid, in most cases, are 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 system’s Power Level Control to the lowest efficient power setting for the application and the selected insert.
®
Section 9: Techniques For Use
9.3 Patient Comfort Considerations Reasons for sensitivity
9.1 Patient Positioning •
•
The backrest of the chair should be adjusted for optimal access to both the upper and lower arches. This assures patient comfort and clinician visibility.
•
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.
•
Have the patient turn head to the right or left.
•
Position chin up or down depending on the quadrant and surface being treated.
•
Applying excessive pressure. Use extremely light grasp and pressure, especially on exposed cementum.
•
Evacuate irrigant using either a saliva ejector or High Vacuum Evacuator (HVE).
•
If sensitivity persists, decrease power setting and/or move from the sensitive tooth to another and then return.
9.2 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 intentionally rounded so there is minimal danger of tissue laceration with proper ultrasonic scaling techniques. Wherever the insert tip is placed in the patient‘s mouth, the lips, cheek and tongue should be retracted to prevent accidental (prolonged) contact with the activated tip.
•
Turn Power Level Control to select ultrasonic power level for operation. Clockwise increases system power. Power level will increase throughout the full range of the control. Hold the handpiece over a sink or drain. Press the foot control to activate the system. Check spray to verify fluid is reaching the working end of the insert tip. Adjust the Lavage Control to ensure adequate flow for the selected power setting. Greater flow settings provide cooler irrigation.
•
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 to tooth interface.
