Equipment description
The micromotor and Apex locator Endus Duo R is a high-precision electronic equipment,
modern and that should be used in endodontics to aid in canal treatments. It is used to
measure the real length of the tooth - (it determines the working length) – until where the
instrumentation and filling will take place, in order for the endodontics treatment to respect
the biologic limits of the dental structure. Combined with the pen for rotatory instrumentation
it allows that the micromotor be manipulated in various patterns, in rotatory mode or
reciprocal mode of the instrument.
Main characteristics:
- Easy-access LCD visible panel;
- Activation on the own handpiece;
- Adjustable speed of rotation and torque;
- It has 9 pre-defined programmings;
- Double-frequency apex locator;
- Four modes of operation;
- It allows the use of diverse types of drills and files;
- Automatic reverse by torque and reduction of speed by torque;
- Adjustable direction of rotation (left/right);
- 2 reciprocal systems (VDW e DENTSPLY);
- Automatic bivolt switched power supply which allows the use of the equipment in any
voltage source from 100 to 240V~ - 50/60Hz;
- Rechargeable high capacity Li-ion battery;
- Automatic Power off;
- Low noise and vibration level.
Principles and foundations applied to the proper functioning of
the product
Apex Locator: It is understood that the tooth works like a capacitor with the accumulation
of electric charges at the periodontium and on the inside of the radicular canal. The dentine
works as an isolator for the propagation of electric current along all the extension of the
radicular canal.
The Apex locators work with the principle of the constancy of electric current between the
oral mucosa and the periodontal ligament. The electronic method considers the difference
on the electric conductivity of a metallic instrument on the inside of the radicular canal and
the conductivity of the periapical tissue. The electric current existing on the radicular canal
would complete the circuit at the moment that the electrode, file, would touch the tissue
fluid, indicating the most apical portion of the radicular canal, “the apical foramen”.
Electric micromotor: Its functioning principle is based on the magnetic field, which
will induce the rotor to spin when a direct current is applied to its poles.
