Bilateral Gum Chewing as Proprioceptive Sensorimotor Re-Education for Patients with Masticatory Muscle Weakness Presenting with Orofacial Pain and Perceived Occlusal Change: A Technical Note with a Retrospective Case Series.
Article in Bioengineering (Basel, Switzerland), 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
Within the Diagnostic Criteria for Temporomandibular Disorders, masticatory myalgia is framed around muscle hyperactivity, yet a recognizable subgroup shows the opposite profile-low muscle tone, fatigue, masticatory pain, and a persistent sense that the bite no longer fits, without structural dental change-and responds poorly to conventional conservative care. We introduce G-SCORE (Gum-chewing-mediated Sensorimotor Calibration of Occlusion through Rhythmic Exercise), a proprioceptive recalibration strategy delivered as a bilateral gum-chewing (BGC) protocol: two equal halves of one sugar-free gum chewed simultaneously and symmetrically on both posterior segments in short, patient-titrated sessions, delivering balanced, rhythmic, low-load input to the trigeminal sensorimotor system. In a retrospective series of 41 patients, we characterized within-subject changes in pain, mandibular mobility, and occlusal parameters. Masticatory pain fell from 5.0 ± 2.9 to 0.7 ± 0.9 (0-10;
