Postoperative pain after emergency pulpectomy with or without photobiomodulation in symptomatic irreversible pulpitis A randomized clinical trial.
Trial report in Scientific reports, 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
To evaluate postoperative pain following emergency pulpectomy in permanent teeth diagnosed with symptomatic irreversible pulpitis and to compare outcomes with or without adjunctive low-level laser therapy (LLLT). This parallel, randomized, single-blind clinical trial included 70 patients with permanent teeth diagnosed with symptomatic irreversible pulpitis. Patients were randomly assigned to two groups (n = 35 each): the experimental group received gallium-aluminum-arsenide laser therapy (808 nm, 100 mW), while the control group received no laser intervention. Postoperative pain was assessed using the Numerical Rating Scale (NRS-10) and the Visual Analogue Scale (VAS). Bite sensitivity was evaluated before and after emergency treatment. Demographic characteristics and analgesic intake were recorded. The primary outcome was postoperative spontaneous pain assessed at multiple time points. Secondary outcomes included bite sensitivity and analgesic intake. Time-dependent reductions in postoperative pain were observed in both groups. Inter-group comparisons showed statistically significant differences at isolated time points (12 and 24 h), with higher pain scores in the experimental group; however, these differences did not translate into a significant overall treatment effect. Longitudinal analysis accounting for repeated measures demonstrated a significant effect of time (p = 0.001), while treatment group was not a significant determinant of postoperative pain. Effect estimates are presented with 95% confidence intervals. Within the limitations of this pragmatic emergency-care study, adjunctive low-level laser therapy was not associated with a reduction in postoperative pain in permanent teeth with symptomatic irreversible pulpitis.
