from the handpiece to the
operating eld. While
breakage is highly unlikely
under normal use, abuse
of the insert may create a
safety hazard. Inspect the
insert and the light guide
for any visible damage
before each use.
Do not bend or reshape
insert. Inserts should be
handled with care at all
times. Ultrasonic insert tips
that have been bent,
reshaped or otherwise
damaged are susceptible
to in-use breakage and
should be discarded and
replaced immediately.
Make sure the insert’s
green O-ring is in place
before use, and lubricate
with water prior to inserting
into the handpiece.
Replace worn or damaged
O-rings with Parkell Stock
No. DORING-GR.
During scaling procedures,
all intra-oral soft tissues
should be protected to
avoid contact with the
vibrating tip. To avoid
gouging the tooth, keep the
tip parallel to (not
perpendicular to) the
tooth’s long axis. Use a
controlled wiping motion,
with copious water
irrigation.
While Parkell “Universal”
tips and “Burnett
Power-Tips™” may be
used at any power setting
from “low” to “high”, thin
“Perio-style” tips should
not be used above your
scaler’s “medium” power
setting.
