Evaluation of Postoperative Pain Frequency in Single-Session Endodontic Treatments With Patency and Foraminal Enlargement.
Article in Clinical and experimental dental research, 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
objectiveThis study aimed to evaluate the incidence of postoperative pain in single-session endodontic treatments with foraminal instrumentation, considering factors such as pulpal diagnosis, tooth position, type of endodontic sealer, and sealer extrusion. MATERIALS AND
methodsTreatments were performed on 153 teeth of patients aged 12-80 years diagnosed with asymptomatic irreversible pulpitis or asymptomatic pulpal necrosis with or without periapical lesions. The obturation sealers used were AH Plus, Endomethasone-N, and Sealer Plus. Postoperative pain intensity was recorded by patients using a modified numerical rating scale (NRS) ranging from 0 (no pain) to 10 (severe pain).
resultsNo statistically significant differences in pain scores were found at 12, 24, or 48 h in relation to gender, age, tooth position, pulpal diagnosis, type of sealer, or extrusion (p > 0.05). The most common pain levels classified as uncomfortable were observed at 12 and 24 h, while 94.1% of patients reported no pain at 48 h; the remaining pain was mild. Pain scores decreased significantly after 48 h for all variables.
conclusionSingle-session endodontic treatment with foraminal instrumentation showed a low incidence of postoperative pain that was not influenced by the variables analyzed in this study. NULL HYPOTHESIS: The null hypothesis was that there was no association between the occurrence of postoperative pain and (i) age, (ii) patient gender, (iii) pulp diagnosis, (iv) tooth position, (v) endodontic sealer type, and (vi) sealer extrusion.
