Accuracy of Electronic Apex Locators ProMark, RootZX II and NRG Rider on Working Length of Multi-rooted Teeth

NCT02521909 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 20

Last updated 2017-06-22

No results posted yet for this study

Summary

The purpose of this study is to compare the accuracy of different apex locators. Before root canal therapy, dentists use a device called an electronic apex locator (EAL) to measure the root canal and to locate its opening at the tip of the tooth's root (called the apical foramen). A root canal is the space inside the root of a tooth. If the tissue within the root canal becomes infected, dentists may perform root canal therapy.

Interventions

DEVICE

ProMark (Tooth Extraction for Assessment of Different Apex Locators)

The purpose of this study is to compare the accuracy of different apex locators on teeth that are scheduled for extractions. Before root canal therapy, dentists use a device called an electronic apex locator (EAL) to measure the root canal and to locate its opening at the tip of the tooth's root (called the apical foramen). A root canal is the space inside the root of a tooth. If the tissue within the root canal becomes infected, dentists may perform root canal therapy.
