Endodontic Management of a Taurodontic Mandibular Second Premolar with Five Canals: A Case Report.

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
This case report presents the endodontic management of a hypertaurodontic mandibular second premolar with five root canals, a rare and complex anatomical variation. A 12-year-old male patient presented with a previously treated tooth (history of pulpotomy) with symptomatic apical periodontitis and necrotic pulp. Initial periapical radiographs suggested taurodontism, but conebeam computed tomography (CBCT) revealed the presence of five canals merging into four distinct apices. Under CBCT guidance, all canals were negotiated, cleaned, and shaped. An apical barrier was created with bioceramic material, followed by obturation using warm vertical condensation with resinbased sealer. At the sixmonth followup, the tooth was asymptomatic and radiographically satisfactory. This case highlights the diagnostic indispensability of CBCT in detecting intricate root canal configurations in taurodontic teeth and outlines a structured clinical protocol for managing such challenging anatomies.
