Cavitron™ JET Combination System UltrasonicScaler and Air Polishing Prophylaxis System

Introduction

Directions For Use

DENTSPLY® Preventive Care is an ISO9001 and EN46000certified company. The Cavitron™ JET Combination System isclassified by Underwriters Laboratories Inc. with respect to electricshock, fire, mechanical hazards only in accordance UL 2601-1and Can/CSA C22.2 NO. 601, assigned control # 13VA.

The Cavitron™ JET dental prophylaxis system is a precisionengineered and manufactured instrument. It contains controlsand components for ultrasonic scaling and air polishing modes.

The System operates by converting ordinary AC house currentinto high frequency current. The ultrasonic system consists oftwo parts: an insert, and the SPS (Sustained PerformanceSystem™) electronic system. The SPS™ system incorporates twoclosed loops. One provides automatic tuning (operating frequencyis adjusted to be at resonance for each insert), the second loopautomatically controls the tip stroke over different workingconditions. The Cavitron™ JET Combination System produces30,000 microscopically small strokes per second at the insert’sworking tip. This combined with acoustic effects of the coolantwater, produces a synergistic action that literally “powers away”the heaviest calculus deposits while providing exceptionaloperator and patient comfort.

With the addition of the Air Polishing function, your Cavitron™

JET becomes a complete prophylaxis system. Mode selection isautomatic when you place the Airpolishing insert nozzle or one ofthe interchangeable 30K™ ultrasonic inserts into the handpiece.

Section 1: Indications

Section 2: Contraindications and Warnings

Section 3: Precautions

3.1 Precautions for All Systems

Ultrasonics

• Do not place the System on or next to a radiator or otherheat source. Excessive heat may damage the System’selectronics. Place the System where air is free to circulateon all sides and beneath it.

• The System is portable, but must be handled with carewhen moving.

• Equipment flushing and dental water supply systemmaintenance are strongly recommended. See Water

Supply under Section 9: System Care.

• Close the coolant water shut-off valve to the System everynight before leaving the office. The use of an in-line waterfilter is recommended.

2.1 Contraindications

• Ultrasonic Systems should not be used for restorativedental procedures involving the condensation ofamalgam.

• For best performance, use only ultrasonic insertsmanufactured by Dentsply® Preventive Care.

• Use only Cavitron® Prophy-Jet® Cleaning Powder.

1.1 Ultrasonic procedures

• All general supra and subgingival scaling applications.

• Periodontal debridement for all types of periodontaldiseases.

• For patients with a history of sensitivity to ultrasonics.

• Endodontic procedures.

2.2 Warnings

• Persons fitted with cardiac pacemakers have beencautioned that some types of electronic equipment mightinterfere with the operation of a pacemaker. Although noinstance of pacemaker interference has ever been reportedto DENTSPLY®, we recommend that the handpiece andcables be kept at least 6 to 9 inches (15 to 23 cm) awayfrom any pacemaker and pacemaker leads during use.

• Do not direct the air polishing stream at soft tissue orinto the sulcus. Tissue emphysema has been reportedlycaused when the air/water/powder stream was directedat the soft tissues or into the sulcus.

Air Polishing

• The use of an air dryer on the compressor line supplyingthe System will prevent condensation from forming inthe air line which in turn may cause “caking” of the airpolishing cleaning powder and clogging the lines at theair polishing tip.

• Cavitron® Prophy-Jet® Cleaning Powder is a water-solublesodium bicarbonate powder specially formulated for use in

1.2 Air polishing procedures:

• Removal of a variety of extrinsic stains, e.g., tobacco,coffee & tea, chlorhexidine.

• Prophylaxis of orthodontic patients.

• Preparing tooth surfaces prior to bonding and sealantprocedures.

3.2 Precautions for Ultrasonic ProphylaxisProcedures

• Like a toothbrush, ultrasonic inserts “wear out” withuse. Inserts with just 2 mm of wear lose about 50% oftheir scaling efficiency. In general, it is recommended thatultrasonic inserts be discarded and replaced after 2 mm ofwear to maintain optimal efficiency and avoid breakage.

• If excessive wear is noted, or the insert has been bent,reshaped or otherwise damaged, discard the insertimmediately.

• Ultrasonic insert tips that have been bent, damaged, orreshaped are susceptible to in-use breakage and shouldbe discarded and replaced immediately.

• Retract the lips, cheeks and tongue to prevent contactwith the insert tip whenever it is placed in the patient’smouth.

Cavitron® Air Polishing Systems. Do not attempt to useany other cleaning materials in the air polishing powderreservoir.

• Empty the air polishing powder reservoir at the end ofthe day to prevent “caking” of the powder and cloggingthe lines and air polishing tip.

4.2 General Infection ControlRecommendations

• As with all dental procedures, use standard personalprotection equipment (i.e., wear face mask, eyewear or faceshield, gloves and protective gown).

4.3 Water Supply Recommendations

It is highly recommended that all dental water supply systemsconform to applicable CDC (U.S. Centers for Disease Controland Prevention) and ADA (American Dental Association)standards, and that all recommendations be followed in terms offlushing, chemical flushing, and general infection controlprocedures. See sections 4.2 and 9.

Section 3: Precautions cont'd

3.3 Precautions for Air Polishing Procedures

• Only set the air polishing powder flow control to themaximum position (H) when it is necessary to removeparticularly difficult stains. Return the powder flowcontrol to the medium position upon the completion ofthe procedure.

• Avoid prolonged or excessive use on restorative dentalmaterials.

• As with high speed handpieces, and other dental devices,the combination of water and ultrasonic vibration fromyour Cavitron™ JET Combination System will createaerosols. With proper technique, much of the Cavitron™

JET Combination System’s aerosol dispersion can beeffectively controlled and minimized. Please carefullyfollow the procedural guidelines in this manual regardingthe use of your System.

• For maximal operator and patient safety, carefully followthe Infection Control Information procedures detailedon the reference card accompanying your System.

• Avoid prolonged use on cementum or dentin.

• Avoid prolonged use on polished metal surfaces as amatte finish may result.

• Patients who are on a restricted sodium diet, or havesevere respiratory illness, should consult their physicianbefore undergoing air polishing prophylaxis procedures.

• Patients wearing contact lenses should remove themprior to air polishing treatment.

Section 5: Installation Instructions

5.1 General Information

If the installation of your Cavitron™ JET Combination System isperformed by someone other than trained DENTSPLY® Dealerpersonnel, care should be taken to observe the following require-ments and recommendations.

5.2 Water Line Requirements

• The System’s water supply line is factory installed. Donot disconnect from the System.

• Incoming water supply line pressure to the System mustbe 25 psi (172 kPa) to 60 psi (414kPa). If your dentalwater system’s supply line pressure is above 60 psi(414 kPa), install a water pressure regulator on the supplyline to your Cavitron™ JET Combination System.

• A manual shut-off valve on the dental water systemsupply line should be used so that the water can becompletely shut-off when the office is unoccupied.

• A filter in the dental water system supply line is recom-mended so that any particulates in the water supply willbe trapped before reaching the System.

Section 7: Accessories

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 as for otherdental procedures. This assures patient comfort andclinician visibility.

7.1 Accessories List*

1. AC Power Cord Set

2. Cavitron® Ultrasonic Inserts

3. Cavitron™ Jet Insert Nozzle

4. Dual position Foot Switch Assembly

5. DualSelect™ Medicament Dispensing System

6. JetShield™ Aerosol Reduction Device

*For detailed information, contact your local DENTSPLY® Representative.

• Have the patient turn their head to the right or left. Alsoposition their chin up or down depending upon thequadrant and surface being treated. Evacuate irrigantusing either a saliva ejector or HVE.

8.2 Performing Ultrasonic ScalingProcedures

NOTE: Refer to the Infection Control Information card (Formno. 80722) supplied with your Unit for general procedures to befollowed at the beginning of each day and between patients.

• The edges of Cavitron® Ultrasonic Inserts are intention-ally rounded so there is little danger of tissue lacerationwith proper ultrasonic scaling technique. Whenever theinsert tip is placed within the patient’s mouth, the lips,cheek and tongue should be retracted to prevent acciden-tal prolonged contact with the activated tip.

• Hold the empty Handpiece in an upright position andactivate the Foot Control until fluid exits.

• Lubricate the rubber O-ring on the insert with waterbefore placing it into the handpiece. Fully seat insert witha gentle push-twist motion. DO NOT FORCE.

• Set the Unit’s Power Adjustment knob to the lowestpower setting for the application and the selected insert.

• Activate the Foot Control and hold the Handpiece over asink or drain. Check spray temperature to verify fluid isreaching the working end of the insert tip. Adjust theLavage flow knob to ensure adequate flow for theselected Power setting. Greater flow settings providecooler irrigant.

• It may be necessary to adjust lavage with the System in“Boost” mode (Foot Control fully depressed) soadequate fluid will be available to cool tip, tooth interface.

• In general, it is suggested that a “feather-light-touch” beused both supra- and subgingivally. The motion of theactivated tip and acoustic effects in the irrigating fluid, inmost cases, is adequate to remove even the mosttenacious calculus.

• Use Cavitron® efficiency indicator if an insert seems torequire increased finger pressure to function adequately.

• The use of a saliva ejector or HVE is recommendedduring all procedures.

8.3 Patient Comfort Considerations

Reasons for sensitivity

1. Incorrect tip placement. Point should be directed awayfrom root surfaces.

2. Not keeping tip in motion on tooth. Do not allow theinsert to remain in a static position on any one area ofthe tooth. Change the insert’s path of motion.

3. Applying pressure. Use extremely light grasp andpressure, especially on exposed cementum.

4. If sensitivity persists, decrease power setting and/ormove from the sensitive tooth to another and thenreturn.

• Select the appropriate amount of powder using the dial onthe Cavitron™ JET or PROPHY-JET® 30 air polishingsystem.

• Verify that slurry exits from the cup when held outsidethe mouth; adjust saliva ejector as necessary.

• Divide the tooth visually into segments to polish (incisal,middle, and gingival).

• Apply cup to middle third with light pressure so cup flaresslightly.

• Pivot nozzle inside the cup to adapt to incisal, gingival,mesial and distal surfaces.

• Apply two seconds of spray for each segment of the tooth,releasing the Foot Control each time. If spray escapes,readjust cup to maintain flat contact with tooth surface.Adjust angle by pivoting nozzle inside the JetShield™cup.

• The suction from the JetShield™ can be used to removeexcess saliva from the patient's mouth.

• After completing each procedure, dispose of clearJetShield™ assembly according to Federal, State, and localregulations. Properly disinfect all other JetShield™accessories prior to reusing them on future patients.

5) Place ejector tube clip around ejector tube and handpiece cablesuch that cables drape together for patient and cliniciancomfort.

6) (Optional) Place handpiece clip along handpiece, close tohandpiece/cable connection, such that clip is holding theJetShield™ evacuation tube in place along handpiece.

7) Verify that slurry exits from the JetShield™ when air polishingunit is activated. Adjust saliva ejector as necessary.

8) Proceed with routine air polishing, applying cup to tooth socup flares slightly. Pivot nozzle inside cup, adapting to mesialand distal surfaces. Apply 2 seconds of spray for each segmentof tooth, releasing foot control each time.

Section 8: Techniques for Use cont'd

• The recommended normal procedure is to clean 2-3 teethwith the air polishing spray (foot control depressed to thesecond position) and then rinse the area with water only (footcontrol depressed to the first position) to inspect the work sitebefore proceeding to the next 2-3 teeth. If desired, the bleed air(foot control released) passing through the air polishing insert tipcan be used to dry the work site during inspection.

• Flushing the patient's tongue with water only (foot controldepressed to the first position) helps reduce the saline taste)

• Maintain a 3 to 4mm insert tip-to-tooth operating distance.

• The patient's lip should be held between the thumb and indexfinger of your free hand and pulled out and up, or down, toform a "cup". Do not retract the lips.

• Tilt the patient's head toward you to help prevent puddling inthe cupped lip and minimize aerosol dispersion.

• Use a saliva ejector or HVE.

• In the posterior regions, use the cheek to help contain aerosolspray.

8.7 Performing Air Polishing procedures without JetShield™

8.8 Proper Angulation of the Air Polishing Insert without JetShield™

Recommended angulation on theanterior teeth is 60° with the tip aimedat the middle third of the tooth surface.

Recommended angulationto occlusal surfaces is 90°.

Recommended angulation on the buccal andlingual surfaces of posterior teeth is 80° withthe tip aimed slightly distally.

• When air polishing the facial surfaces of the anteriors, center thespray on the middle third of the tooth and use a constantcircular motion. The edge of the spray will clean the teeth to thegingiva.

• Do not aim directly at the soft tissue.

• Avoid prolonged use on polished metal surfaces as a matte finishmay result.

• In the upper anterior region, use the upper lip and your hand asa shield to help contain the aerosol spray.
