The Impact of Different Final Irrigation Activation Techniques on Postoperative Pain in Single Rooted Mandibular Premolar Teeth: Randomised Clinical Trial.
Trial report in European endodontic journal, 2025. 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
Objectives The trial was conducted to assess the impact of passive ultrasonic irrigation, XP endo finisher, AF max file, and manual dynamic agitation on postoperative pain and analgesic consumption at 6 h., 12 h., 24 h., 48 h., 72 h., and a week later on single-rooted lower premolar teeth with acute irreversible pulpitis and apical periodontitis. Methods. Seventy patients were contributed in the trial. A total of 64 eligible patients were randomized into four equal groups (n=16 per group). Considering the irrigation activation approach, participants were separated into four groups as follows: Group 1: passive ultrasonic irrigation. Group 2: XP-endo Finisher. Group 3: Fanta AF max file Group 4: Manual dynamic agitation. Following the root canal procedure, the intensity of postoperative discomfort was measured by a verbal rating scale. The frequency and quantity of analgesics used were recorded. Results. Using an analysis of variance (ANOVA), there was a statistically significant difference between the percentage of preoperative and postoperative pain at most of the follow-up period (p<0.001**) in each group. Additionally, a significant difference (p<0.05) in the postoperative pain level and analgesic consumption was found among groups and most of the time intervals. Shapiro-Wilk and Kolmogorov-Smirnov tests, the Chi-square test, Fisher's exact test, and the McNemar test were used. The excessive percentage of postoperative pain and analgesic intake was found in the MDA group, followed by the Max file and the XPF, while the lowest postoperative pain and analgesic intake were related to the PUI group. There was a significant difference (p<0.05) between the PUI and MDA groups in the degree of pain severity and increase in analgesic intake at 72 h. Regarding the percentage of swelling, there was a statistically notable difference (p<0.05) between groups after 24 h time intervals. Conclusions Minimal postoperative pain and minimal analgesic intake were significantly accompanied by passive ultrasonic irrigation, while PUI and analgesic intake were increased in MDA.
