Sirona ENDO 6:1 handpiece or SIRONiTi APEX
For endondontic treatments with the ApexLocator the Sirona handpiece
ENDO 6:1 (from SN 6407 / July 2010) is required; in the motor dialog
(without torque control), the Sirona handpiece SIRONiTi Apex is required.
One apex instrument hose exists for each of the motor BL E A and BL ISO
E B, in which the Apex cable runs. The connecting threads of these
motors C have gold-plated contact surfaces. The gold plating ensures
electrical conductivity.
When using the BL E motor, the (Apex) basic adapter D must be used as
a transition piece. This also has a gold-plated contact.
The motor end of the Apex instrument hoses is identified by a blue
connecting nut.
Pull the silicone isolation sleeve E over the handpiece and wear insulating
gloves to avoid faulty measurements due to leakage current. During the
measurement, the instrument must not come into contact with the
patient's mucosa or the mucosal electrode. We recommend the use of a
cofferdam for treatment.

Standardizing the measuring system
Before starting the apex measurement, a functional check or
standardization of the measuring system can be performed by shorting
the electrodes. This cancels out any inaccuracies caused by skips in
impedance in the measurement setup.
➢ Short the electrical measurement system. Plug in the files and hold
them directly against the mucosal electrode.
If a short signal is heard and the distance display appears with no
bars, the standardization was successful. If not, check the
electrical connections for signs of damage.
WARNING
The silicone isolation sleeve is a disposable item and must be sterilized
before use.
Details can be found in the section “Cleaning and disinfecting/sterilizing
the components of the ApexLocator” [ → 231].
