Clinical Evaluation of Working Length Determination by Electronic Apex-Locator or Radiography on Adequacy of Final Working Length

Not Applicable

• Conditions: Root Canal
• Interventions: Device: Electronic Apex Locator; Device: Dental Radiography

• Registration Number: NCT00901810
• Lead Sponsor: Shiraz University of Medical Sciences

Brief 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.
