This assures patient comfort andclinician visibility.• Hold the empty handpiece in an upright position over asink or drain. Activate the Foot Control until water exits.• Lubricate the rubber o-ring on the insert with waterbefore placing it into the handpiece. Fully seat insertwith a gentle push-twist motion. DO NOT FORCE.• Activate the System. Hold the handpiece over a sink ordrain. (Check spray to verify fluid is reaching the working end of the insert tip). Adjust the Water Control knobto ensure adequate flow. Greater flow settings providecooler irrigant.• In general, it is suggested that a "feather-light touch" beused for ultrasonic scaling. The motion of the activatedtip and acoustic effects of the water, in most cases, isadequate to remove even the most tenacious calculus.• Periodically check the Cavitron Ultrasonic Insert forwear with the Cavitron Insert Efficiency Indicator.• The use of a saliva ejector or High Volume Evacuator(HVE) is recommended during all procedures.• Set the ultrasonic scalerʼs Power Control knob to thelowest effective power setting for the application and theselected insert.• Have the patient turn his/her head to the right or left.Also position chin up or down depending upon thequadrant and surface being treated. Evacuate irrigantusing either a saliva ejector or High Volume Evacuator(HVE).8.2 Performing Ultrasonic Scaling Procedures• Note: Refer to the Infection Control InformationBooklet supplied with your system for generalprocedures to be followed at the beginning of each dayand between patients.• The edges of Cavitron® Ultrasonic Inserts are intentionallyrounded so there is little danger of tissue lacerationwith proper ultrasonic scaling technique. Wheneverthe insert tip is placed in the patientʼs mouth, the lips,cheek and tongue should be retracted to preventaccidental contact with the activated tip.8.3 Patient Comfort ConsiderationsReasons for sensitivity• Incorrect tip placement. The point should never bedirected toward tooth root surfaces.• 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 insertʼs path of motion.• Applying excessive pressure. Use a very light graspand pressure, with a soft tissue fulcrum wheneverpossible, especially on exposed cementum.• If sensitivity persists, decrease power setting and/ormove from the sensitive tooth to another and then return.ENGLISH • 8
