Clinical Trial 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.

Eligibility

Inclusion Criteria:

• All the patients who are referred for Root Canal Therapy

Exclusion Criteria:

• Blocked Canals

• Open Apexes

Related Conditions & MeSH terms

• Root Canal

Intervention

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.
• 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.
