1. GENERAL INFORMATION
1.1. The device designation:
The device EndoEst-Apex 02 is designed for root canal apical
constriction localization at the time of endodontic treatment.
Two modifications of the device are available in the production range
as in the below table 1
Table 1.
The device is locate the apical constriction by complex electrical
resistance measuring between two electrodes. One of the electrodes is
a metal hook (lip clip), placed on patient’s lip and the other electrode
(file clip) is connected to the metallic part of the endodontic file,
placed into the tooth root canal.
1.2. Field of application:
