Postoperative pain and quality of life after sonic irrigation with Waterpik dental flosser home care device: a randomized clinical trial.
Article in European oral 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
Purpose: This study aimed to evaluate the effect of irrigation agitation on postoperative pain (PP) and oral health-related quality of life (OHQoL) in patients undergoing single-visit root canal therapy (RCT). Materials and methods: The study was a double-blind randomized clinical trial where a single-visit RCT was performed on forty patients diagnosed with symptomatic irreversible pulpitis in molars. The study participants were divided into two groups (n=20) based on the final irrigation protocol. Group 1- No agitation (NA), Group 2: Sonic agitation (SA). The pain scores were recorded using the Visual Analogue Rating scale (VAS) preoperatively and postoperative at 6, 12, 24, 48 and 72 hours. The OHQoL scores were recorded before and 72 hours after the treatment using the oral health impact profile (OHIP-14). Statistical analysis was performed for inter- and intra-group comparisons using Mann-Whitney U test and the Wilcoxon Signed Rank Test. Results: Lower pain scores were observed in the sonic agitation group at 12 hours (p=0.03),24 hours(p=0.02),48 hours (p=0.02),72 hours (p=0.04) after RCT. The patient's OHQoL was improved postoperatively (p=0.278), but there was no significant difference between sonic agitation and the control groups. Conclusion: Endodontic treatment improved patients' quality of life, and sonic irrigation agitation using a Waterpik device reduced postoperative pain in patients with symptomatic irreversible pulpitis.
