Abstract
The purpose of this study was to evaluate the accuracy of the frequency-dependent apex locator in determining canal length in a moist environment. A total of 84 canals from 71 teeth were evaluated. The frequency-dependent apex locator ROOT-ZX was
used
to determine the position of the file tip. After taking a radiography with a file in the canal, the distance from the radiographic apex to the file tip was measured, and the distances in vital pulp and in nonvital pulp were compared.
@ES The results were as follows:
1. The frequency-dependent apex locator located the file to the apex in 95.2% of the canals so accurately that we need not take another radiograph in order to correct working length.
2. The vital pulp and hemorrhage did not affect the accuracy of the frequency-dependent apex locator.
