Working Length Determination in Simulated Apical Resorption and Horizontal Root Fracture Using Root ZX and a Novel Integrated Apex Locator: A Comparative Study
Conservative Dentistry and Endodontic Journal
Aim: The current study aimed to compare the efficacy of working length measurement in different simulated clinical scenariosapical root resorption and horizontal root fracture using a new integrated apex locator SCM 008 (Fanta dental materials) and ROOT ZX (J Morita). Materials and methods: Forty recently extracted single-rooted mandibular premolar teeth were taken. Allotted into two major groups under two apex locators. Each group was subdivided into two, based on the different simulated
... ent simulated conditions. In horizontal root fracture group, an oblique notch was made on the external root surface 8 mm from the anatomic apex. To simulate apical root resorption, an irregular defect was drilled at the apex with a round bur. Teeth were embedded in a customized holder containing alginate simulating the periodontal ligament. Electronic measurements were taken and compared. Statistical analysis: One sample t-test. Results : Though values were more accurate in the case of Root ZX, the result obtained was not significant statistically. Conclusion: In the case of both horizontal fracture and apical resorption, Root ZX and the new integrated apex locator could perform with superior efficacy in the given experimental conditions.
