Clinicians must effectively manage endodontic testing to better achieve successful diagnoses of injured teeth. Taking accurate periapical radiographs and bitewings is a critical part of the process. In addition to radiography, however, apex locators have become an instrumental tool in helping dentists perform high-quality endodontic care. Having undergone various generations of advancements, these instruments help clinicians eliminate guesswork in achieving accurate working lengths when performing root canal therapies.
