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

Completed

Conditions studied: Dental Pulp Diseases

In brief

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.
