An Innovative Approach for Retrieval of a Separated Intracanal File Using Guided Endodontics: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A separated instrument in a root canal limits accessibility for chemo-mechanical preparation, making its retrieval imperative for a good prognosis. Among the numerous techniques available for instrument retrieval, guided endodontics is arguably the most predictable. This case report describes a stepwise approach for instrument retrieval using a surgical drill guided by a 3D-constructed acrylic template with the aid of cone beam computed tomography (CBCT). A 22-year-old male patient of North Indian origin presented with a chief complaint of discoloration and pain in tooth 21. Radiographic examination revealed poor obturation and fractured instruments in the middle third of the root canal. A diagnosis of a previously treated tooth with symptomatic apical periodontitis was made. After obtaining the patient's consent, CBCT imaging and an intraoral scan were performed to generate Digital Imaging and Communications in Medicine (DICOM) and standard tessellation language (STL) files, respectively. These files were merged using Blue Sky Plan software (Blue Sky Bio, LLC; Grayslake, Illinois) to create a virtual drill path, which was subsequently used to fabricate a 3D acrylic guide, leading to the successful retrieval of the fractured instrument. Guided endodontics offers a predictable method for fractured instrument retrieval.
