Summary

Accurate length determination of root canal is essential in root canal therapy. Radiography has been the conventional method for this measurement but recently several in-vitro studies have shown that new generations of Electronic Apex locators are as accurate as radiography in length determination. It is hypothesized that the latest generation of Electronic Apex locator can produce acceptable results as radiography when used for length determination.

Conditions

• Root Canal

Interventions

Type	Name	Description
DEVICE	Electronic Apex Locator	Electronic Apex Locator is used to find the apical foramen of the root canal. It uses a weak electrical current passed through the canal by endodontic file.
DEVICE	Dental Radiography	Radiography is used to measure the length of root canal by putting an endodontic file in the canal and taking the radiography to measure the length.
