Objectives and Goals

  • List and describe the various methods for determining working length.
  • Compare the accuracy of radiographs vs. electronic apex locators in determining working lengths.
  • List the indications and contra-indications for the use of E.A.L.'s.
  • List the potential errors and inaccuracies inherent in the use of E.A.L.'s and radiographs for working length determination.
  • Compare and contrast the paralleling and bisecting the angle technique as they pertain to working length determination.
