Outcome of Guided Pulpal Regeneration in Immature Molar Teeth with Chronic Apical Abscess: A Case Report and Mini-Review.
Article in Frontiers in dentistry, 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
This case report describes guided pulpal regeneration (GPR) of two immature permanent molar teeth with chronic apical abscess, thin dentinal walls, and open apices. Both teeth were treated with an identical protocol in two sessions, with minimum instrumentation with hand files, irrigation with 1.5% sodium hypochlorite (NaOCl), and application of 1:1 mixture of ciprofloxacin and metronidazole as an intracanal medicament, blood clot as a scaffold, and mineral trioxide aggregate (MTA) as the capping material. At the one-year follow-up, both treated teeth were asymptomatic. However, the root development procedure was different even in different roots of the same tooth, varying from only an increased thickness of dentinal walls to complete closure of the apex along with an increase in root length and dentinal wall thickness. It is concluded that the outcome of GPR is not completely predictable, and may vary among teeth with similar initial conditions and treatment approaches.
