  Purpose

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.

Primary Outcome Measures:
  • adequacy of final working length [ Time Frame: at the end of cleaning and shaping ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 280
Study Start Date: April 2009
Estimated Study Completion Date: August 2009
Estimated Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Apex Locator
Working length for cleaning and shaping of the canal is measured by Electronic Apex Locator in this group.
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.
Other Names:
  • RootZX
  • Raypex
Active Comparator: Radiography
Working length for cleaning and shaping of the canal is measured by Radiography in this group.
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.
Other Name: pre apical Radiography
