INSERT WEAR, CARE, and SELECTION
Inserts wear out with normal use. Compare your insert against the full size illustration on page 8
to gauge how much wear has occurred. A monthly check is appropriate for the DE-5 and DE-6,
however the finer DE-6A should be checked bi-weekly.
When the tip reaches back to the blue line, efficiency is reduced by 25%. When the tip reaches
back to the red line efficiency is reduced by 50% and the insert should be discarded. If the tip is
bent or damaged, discard the insert. Note that only 1mm of wear can reduce power by 50% due
to the mechanical advantage inherent within the internal coupling between the magnetostrictive
stack and the tip.
Be careful to avoid damage to the magnetostrictive stack (the metal laminations behind the
plastic portion). If broken laminations are evident, discard the insert.
Do not clean with an ultrasound cleaner. Never soak the insert. Never allow to run dry.
SETTING POWER
The correct power setting is primarily a function of the tip type. Perio tips and the feline urethral
catheter tips require low power. Using “normal” power with the fine tips may easily break them.
Use the following chart as a guide. Always use the lowest power setting possible to accomplish
the desired result.
NOTE: “Thru-flow” types are generally for supra-gingival use while “Focused spray” types are for
periodontal and sub-gingival use. Lavage terminates immediately when the foot pedal is released
with “Thru-flow” types whereas the “Focused-spray” types produce a stream of water for a short
time after the pedal is released in order to give a full flush of loose detritus.
DE-5
TFI #3
Extrinsic stain and heavy calculus removal
Thru-flow type, commonly called “Beaver tail”
Any low to high power
setting as appropriate
DE-5A
FSI #3
Extrinsic stain and heavy calculus removal
Focused spray type, commonly called “Beaver tail”
Any low to high power
setting as appropriate
DE-6
TFI #10
Light to moderate calculus removal
Thru-flow type, also called “Straight” or “Universal”
Any low to high power
setting as appropriate
DE-6A
FSI-10-S
Light deposit removal and deplaquing pockets <4mm
Focused spray type, also for perio maintenance
Low power only
Use “Specialty” setting
DE-6B
FSI #10
Light to moderate calculus removal
Focused spray type, also called “Straight”
Any low to high power
setting as appropriate
DE-7
Feline urethral catheter
Cavitron® Slimline
TM
, FSI
TM
, or Modified Periodontal inserts
WARNING! Excess power will injure patient!
Low power only
Use “Specialty” setting
NOTE: Use the 30% power boost for brief periods of time to loosen stubborn calculus. Keep the tip moving to avoid
over heating a small area. NEVER use power boost with perio inserts or with the DE-7.
