Intracanal Calcification Following Apexification: A Case Series.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Apexification is a widely employed procedure for managing immature permanent teeth with necrotic pulps, utilizing calcium hydroxide (Ca(OH)₂) and iodoform combinations for canal disinfection and apical barrier formation. While these medicaments are effective, prolonged placement due to missed follow-up appointments may predispose to intracanal calcification, complicating subsequent canal negotiation and obturation. This case series reports three pediatric patients who presented with pain in mandibular permanent first molars exhibiting immature apices (Cvek's stage 4) and periapical radiolucencies. All patients had previously undergone apexification with a Ca(OH)₂-iodoform medicament (Metapex, Meta Biomed Co. Ltd., Cheongju, Korea) but missed scheduled follow-up appointments, reporting after six to 10 months. At recall, clinical symptoms had subsided, and radiographs showed healing of the periapical lesions. However, during re-instrumentation, extensive intracanal calcifications and calcific barriers were observed in the apical third, obstructing complete canal negotiation and interfering with working length determination. This case series emphasizes the importance of strict follow-up compliance and cautious monitoring when employing long-term intracanal medicaments in pediatric endodontics.
