The detection function can also be switched off com-
pletely. Press the key to deactivate this function.
To reactivate the detection function, just press the
key once again.
NOTE
i
The detection function must be deactivated whenever
the SIROPERIO 4 PS or SIROPERIO PE 8 tip is not in
use.
Detection on: The tooth lights up on the display. In this
case, the audible alarm is also switched on.
Detection off: The tooth does not appear on the display.
In this case, the audible alarm also does not appear.
Indication error:
If the signal ring displays neither blue nor green light, this
means that the distal end of the tip is not properly in con-
tact with the root surface or is located in soft tissue, and
that neither the detection nor the removal of calculus can
be performed for this reason. The tooth lights up white
on the display.
Flashing tip on the display:
Other causes of errors include e.g. a worn, broken,
loose, incorrect, missing instrument tip or not correct
plugged-in handpiece supply (see chapter 11).
You can read off the amount of wear from the check card
included in the scope of supply.
NOTE
i
At present, the detection function can be applied only to
root surfaces and calculus.
Detection is not possible on the following surfaces:
enamel, caries* and restorations.
Substantiated in vitro and in vivo studies previously per-
formed have shown that the PerioScan yields a detection
rate of at least 80 %** taking the specified information in-
to consideration. This means a maximal 20 % possibility
still exists that the software will not clearly recognize
whether the contacted tooth surface is calculus or root
surface. The final decision regarding therapy is therefore
up to the dentist.
No detection is possible if the tip gets stuck.
Please probe slowly, since the color change of the signal
ring has been limited to 10 Hz due to the average per-
son's capability to react.
