Incidence and assessment of mechanical allodynia and its association with dental anxiety in endodontic pain: A clinical study.
Article in Journal of conservative dentistry and endodontics, 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
Context: Mechanical allodynia (MA) refers to pain elicited by normally nonpainful stimuli. Clinically healthy teeth may exhibit MA in relation to an endodontically diseased tooth. Aims: The study aimed to assess the prevalence of MA in healthy teeth ipsilateral, contralateral, and opposing teeth to an endodontically diseased tooth, and its association with patient anxiety. Settings and Design: A cross-sectional observational study evaluating patients presenting with endodontic pain. Subjects and Methods: A total of 150 patients diagnosed with symptomatic irreversible pulpitis or symptomatic apical periodontitis in permanent first molars were included. Pain on percussion in ipsilateral, contralateral, and opposing teeth was assessed using the visual analogue scale (VAS). Anxiety levels were measured using the Generalised Anxiety Disorder-7 scale. Statistical Analysis Used: Fisher's exact test, Mann-Whitney U test, and Wilcoxon signed-rank test were applied. The level of significance was set at Results: MA was observed in 44% of ipsilateral and 10.7% of contralateral teeth, with no cases in the opposite arch ( Conclusions: MA may occur in healthy teeth adjacent to or contralateral to endodontically diseased teeth, likely due to central sensitization. Higher anxiety levels were associated with contralateral MA.
