Radiographic Evaluation of Periapical Healing Following Single vs Multiple Visit Root Canal Treatment: A PAI Based Study.
Article in Journal of pharmacy & bioallied sciences, 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
Introduction: This randomized controlled clinical trial compared the radiographic periapical healing outcomes of single-visit versus multiple-visit root canal treatments for teeth with apical periodontitis. Materials and Methods: Thirty patients with single-rooted teeth diagnosed with primary apical periodontitis were randomly allocated to either a single-visit (n = 15) or a multiple-visit (n = 15) group. Periapical healing was radiographically evaluated using the Periapical Index (PAI) score at baseline and at 6 and 12-month follow-up appointments. Results: The results showed no statistically significant difference in the radiographic healing rates between the two groups at either follow-up period. The success rates (PAI score ≤2) were 93.3% for the single-visit group and 86.7% for the multiple-visit group at 12 months ( Conclusion: These findings suggest that both treatment protocols are equally effective in achieving periapical healing, challenging the necessity of an inter-appointment intracanal medicament.
