DENTSPLY Cavitron Prophy-Jet Directions For Use Manual page 17

• Use your free hand and the patient's cheeks or lips to
form a cup to contain aerosols. Tilt the patient's head
toward you to help prevent puddling in the cupped lip and
minimize aerosol dispersion. Rinse excessive slurry from
the patient's mouth thoroughly and often.
• Maintain a 2 to 4 mm tip-to-tooth operating distance.
Keep the tip in constant circular motion and maintain a
sweeping motion from interproximal to interproximal.
When air polishing the anteriors, center the spray on the
middle third of the tooth. The edge of the spray will
clean the teeth to the gingiva. Refer to section 9.6
Proper Angulations for all tooth surfaces.
• Use adequate evacuation. Use of a high-speed suction
(High-Volume Evacuator) with the aid of a dental assistant
is recommended. When performing air polishing without
the aid of a dental assistant, the use of a saliva ejector
and/or aerosol-reduction device is recommended.
• Do not aim directly at the soft tissue.
• Avoid use on surfaces and marginal areas of dental
restorations.
• Prophy Mode Auto Cycles: When performing air polishing
procedures, it is recommended to clean 1-3 teeth with
air polishing spray and then rinse the area with water
in order to inspect the work site before proceeding to
the next 1-3 teeth. Prophy Mode Auto Cycles allow for
automatic cycling between air polishing and rinse while
the foot pedal is in Tap-On™ mode. A small burst of air
is released before the Prophy Mode Auto Cycle begins to
alert the clinician that the cycle is beginning.
• If at any time continuous air polishing is needed, simply
depress the foot pedal all the way to the floor. Release of
the foot pedal will disable Prophy Mode Auto Cycle.
