Clinical and radiographic outcomes and associated factors of iRoot BP plus apical barrier treatment in permanent teeth with open apices and periapical lesions: a retrospective study.
Article in Clinical oral investigations, 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
objectiveTo evaluate clinical and radiographic outcomes of iRoot BP Plus apical barrier treatment in permanent teeth with open apices and periapical lesions and to explore associated factors.
methodsPermanent teeth exhibiting pulp necrosis and open apices treated with iRoot BP Plus apical barrier were retrospectively included with follow-up ≥ 12 months. Treatment outcomes were determined through clinical examinations and radiographic assessments, with results classified as healed, healing, or failure. Quantitative changes in root length, root width, and apical diameter were measured on paired radiographs. Associations between baseline variables and outcomes were examined using chi-square or Fisher’s exact tests.
resultsA total of 54 teeth were included in the final evaluation, with a median follow-up period of 18.5 months (minimum 12 months, maximum 60 months). At final follow-up, 23 teeth (42.6%) were classified as healed, 29 (53.7%) as healing, and 2 (3.7%) as failure. Favorable outcomes (healed and healing) were observed in 52 teeth (96.3%); most teeth (52/54) were asymptomatic. Radiographs showed substantial reduction or resolution of periapical lesions. Periapical index (PAI) was significantly associated with treatment outcome (P < 0.05). Quantitative radiographic measurements indicated increased root length and root width with a reduction in apical diameter during follow-up.
conclusionIn this retrospective cohort, iRoot BP Plus apical barrier treatment showed favorable clinical and radiographic outcomes in permanent teeth with open apices and periapical lesions. CLINICAL RELEVANCE: In this study, PAI was associated with treatment outcomes, which may help clinicians in case assessment and follow-up planning.
