Rare adverse root development after regenerative endodontic procedures: two case reports and contributing factors analysis.
Article in Frontiers in oral health, 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
Regenerative endodontic procedures (REPs) promote continued root development in immature teeth with pulp necrosis. However, endodontic infection or physical trauma during tooth development may lead to abnormal root formation. This report describes two cases of immature teeth with periapical disease secondary to dens evaginatus, both treated with REPs and followed up for 4 years. Uncommon root developments, including root curvature and segmental root formation, were observed. A review of the relevant literature was conducted to identify the potential contributing factors. Clinicians should be aware that even clinically successful REPs may result in unusual root morphology, especially in cases with pre-existing inflammation or concurrent orthodontic treatments.
