Apex measurement via the instrument
The apex is measured by means of an impedance measurement between
the root canal file and mucosal electrode. The Apex measurement signal
is as follows:
● Apex cable in the instrument hose
● Metal housing of the motor
● Metal housing of the ISO adapter, if applicable
● Endodontic handpiece
● Root canal file
● Mucosal electrode
● Apex adapter
E
For endodontic treatments with the ApexLocator, the Sirona ENDO
handpiece 6:1 (starting from SN 6407 / July 2010), ENDO 6L, or ENDO L
is required when using the treatment function; the Sirona handpiece
SIRONiTi Apex is required when the motor program (without electronic
torque limitation) is used.
For each of the motors BL A and BL ISO B, one apex instrument hose is
available, which carries the apex cable. The connecting threads of these
motors C have gold-plated contact surfaces (in BL motors with serial
number 6,000 or higher). The gold plating ensures electrical conductivity.
When using the BL motor, the (Apex) basic adapter D must be used. 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.
ApexLocator, sterilizing silicone isolation sleeve
WARNING
The silicone isolation sleeve is a disposable item and must be sterilized
before use.
