Summary
This study found that electronic apex locators, including Root ZX, Sono Explorer Mark II Junior, and Apit III, accurately detect root perforations. All tested devices proved clinically acceptable for identifying these dental issues.
Area of Science:
- Endodontics
- Dental materials science
Background:
- Root perforations are a complication in endodontic therapy.
- Accurate detection of root perforations is crucial for successful treatment outcomes.
Purpose of the Study:
- To compare the accuracy of three electronic apex locators (Root ZX, Sono Explorer Mark II Junior, Apit III) in detecting artificial root perforations.
- To assess the clinical acceptability of these devices for perforation detection.
Main Methods:
- Thirty extracted human teeth were artificially perforated in the middle third of the root.
- Perforations were detected using K-files attached to the electronic apex locators.
- Radiographic and stereomicroscopic evaluations were performed to determine the file tip's accuracy.
Main Results:
- All tested electronic apex locators demonstrated clinically acceptable accuracy (0.06-0.25 mm mean distance).
- No significant differences were found between morphometric and radiographic measurements.
- The devices showed no significant difference in detecting large versus small perforations.
Conclusions:
- Root ZX, Sono Explorer Mark II Junior, and Apit III are acceptable clinical tools for detecting root perforations.
- The accuracy of these electronic apex locators is suitable for clinical use in endodontics.
