IDENTIFICATION OF THE EQUIPMENT

Dear Customer
Congratulations. You have made a good choice when you decided to buy a GNATUS
QUALITY product comparable to the best products available in the World. This manual is a
general presentation of your product and it will give you important details to help you to
solve possible problems.
Please, read it and keep this with you.
Equipment indication
The indications regarding the use of the Endus Apex locator are below:
• In routine situations of the dental treatment;
• For the detection of perforations, fractures and root reabsorptions;
• For the follow-up of the amount of work during the cleaning and modeling process of
curve roots (dynamic odontometrics);
• Pregnant patients and patients that presented nausea during the radiographic
measurements.
This equipment is for exclusive odontological use, and it should be handled and used by
an expert professional (professional properly certified, according to local legislation of the
country) observing the instructions contained in this manual.
It's an user obligation to use the equipment in perfect working conditions and to protect
himself/herself, the patients and third parties against eventual dangers.
Physics Principle used by the equipment
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 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".
