8.7 Performing Air Polishing
Procedures with JetShield
NOTE: Refer to the Infection Control card supplied with
your System for general procedures to be followed
at the beginning of each day and between patients.
Install JetShield on the Cavitron Air Polishing Nozzle as
instructions indicate in Section 8.6.
Select the proper amount of powder and water to create
the slurry needed using the Powder Flow Control on
the powder bowl cap and the Lavage Control on the
handpiece cable. Ensure that the system's Power Level
Control is in the "Prophy Mode" range. Use more powder
for heavy stains and less powder for light stains. With
experience the Dental Healthcare Professional will be
able to determine the best flow rate settings for optimum
efficiency and patient comfort. Never operate the
system with powder only.
Verify that slurry exits from the cup when held outside
the mouth; adjust saliva ejector as necessary.
Divide the tooth visually into segments to polish (incisal,
middle and gingival).
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.
After completing each procedure, dispose of clear
JetShield assembly according to Federal, State and
local regulations. Properly disinfect all other JetShield
accessories prior to next use.
Apply cup to middle third with light
pressure so cup flares slightly.
Pivot nozzle inside the cup to adapt
to incisal, gingival, mesial and distal
surfaces.
8.8 Performing Air Polishing
Procedures without JetShield
Place a 2 x 2 gauze on lip.
Select the proper amount of powder and water to create
the slurry needed using the Powder Flow Control on
the powder bowl cap and the Lavage Control on the
handpiece cable. Ensure that the system's Power Level
Control is in the "Prophy Mode" range. Use more powder
for heavy stains and less powder for light stains. With
experience the Dental Healthcare Professional will be
able to determine the best flow rate settings for optimum
efficiency and patient comfort. Never operate the
system with powder only.
Flush the patient's tongue with water to help reduce the
saline taste.
The recommended normal procedure is to clean 1-3
teeth with the air polishing spray (Foot Control depressed
to the second position) and then rinse the area with water
(Foot Control depressed to first position) to inspect the
work site before proceeding to the next 1-3 teeth. If
desired, the bleed air passing through the air polishing
insert tip can be used to dry the work site during
inspection (Foot Control released).
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 8.9
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.
