Preventive measure for Apex locator :
- – For accurate readings
- – Acts as an insulator to # 10 K file
- – Avoids leakage of the current
We have seen a revolution in Endodontics in the last two decades. We are convinced clinically to follow crown down technique in clinics since Root Canal Treatment is a blind procedure. In Modern Endodontics. measuring the working length is the most important stage. Radiographs are two dimensional. so they have limitations in locating canals which are opening laterally. Only way to confirm the authentic length of a root canal is using electronic apex locator.
Many times a clinician has to open the pulp chamber in a tooth existing silver filling or metal crown. While performing endo therapy. one needs to use apex locator to confirm the working length of the each canal. Since apex locator are based on electronic current, there is a possibility of leakage of the current because of silver filling or metal crown. Clinician may get faulty readings due to this leakage. Where ever you are not getting proper or stable readings with apex locator or if you see lot of fluctuations on the graph. then it may be a leakage of the current. It is advisable to use i -Sleeve in such canals.
Preendodontic filling or blocking all carrious tooth structure with filling is mandatory before using i – Sleeve. Day by day we are trying to achieve more perfection and ease in using apex locator and i – Sleeve is the good help. Sometimes. clinician may find oral tissue like tongue, cheek or lips interfere the Apex Locator readings, i-Sleeve will prevent leakage of the current.
If you use i – Sleeve on every hand K -file while measuring the working length, leakage is avoided due to insulating effect of i – Sleeve on K file and a stable reading in apex locator can be achieved. Non sterile – Non autoclavable Recommended sterilization – pour alcohol on i – Sleeve.
