EQUIPMENT IDENTIFICATION
Equipment indication
The indications concerning the use of the Endus Duo Apex locator are:
• In routine situations of the endodontic treatment;
• For the detection of perforations, fractures and root reabsorptions;
• For the accompaniment of the length of work during the cleaning process and modeling
of curved canals (dynamic odontometrics);
• Pregnant patients and patients that present nausea during radiographic exposure.
This equipment is exclusively for odontological use, and it should be used and handled
by someone prepared (Duly certified Professional, according to the local legislation of the
country) observing the instructions contained in this manual.
It’s an user obligation to use the equipment only in perfect working conditions and to
protect himself/herself, patients and third parties against eventual dangers.
Physics Principle used by the equipment
Apical locator: It is well understood that the tooth works like a capacitor with
accumulation of electric charges at the periodontal and on the inside of the root canal. The
dentin works like an insulating material for the propagation of electric current throughout
all the extension of the root canal.
The apex locators work based on the principle of constancy of the electric current
between the oral mucosa and the periodontal ligament. The electronic method takes into
consideration the difference of electric conductivity of a metallic instrument on the inside
of the root canal and the conductivity of the periapical tissue. The electric current existing
on the root canal would complete the circuit at the moment that the electrode, file, touched
on the tissue fluid, indicating the most apical portion of the root canal “the apical foramen”.
Electric Micromotor: Its functioning principle is based on the magnetic field, which
induce the rotor to spin when a direct current is applied to its poles.
