Accuracy of Working Length Measurement Using Cone Beam Computed Tomography at Three Field of View Settings, Conventional Radiography, and Electronic Apex Locator: An Ex-vivo Study.
Article in European endodontic journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07689838 (Accuracy and Precision of the Root ZX3 Electronic Apex Locator for Working-Length Determination in Teeth With Different Pulpal and Periapical Conditions), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract
objectivesDetermining the working length (WL) in root canal treatment facilitates the treatment prognosis. The introduction of apex locators and new CBCT devices in dentistry influenced this consideration. This comparative study evaluated the accuracy of working length measurement by cone-beam computed tomography (CBCT) in three fields of view (FOVs), conventional radiography, and the apex locator Raypex 5. METHODOLOGY: The descriptive-analytical study was performed on 40 lower premolar teeth that met the inclusion criteria. Direct observation under the microscope was considered the gold standard and compared with measurements by the electronic apex locator, CBCT, and periapical images.
resultsThe results were analyzed by paired t-tests and Wilcoxon tests. A significance level of 0.05 was considered in this study. CBCT 5×5 FOV with a p-value of 0.733 and analog radiography with a p-value of 0.001 achieved the working lengths with the highest and lowest accuracy, respectively. In addition, the difference between actual and measured working length using analog radiography was significant (p-value <0.05).
conclusionsAccording to the results of this study, CBCT images at different FOVs and those taken by the apex locator Raypex 5 can be used as a reliable method for estimating the working length. (EEJ-2023-10-141).
