Evaluation of Temporomandibular Joint Structures and Conditions Using Dental-Dedicated MRI: A Feasibility Study.
Article in Journal of oral rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMRI is the most viable alternative to depict the soft tissues of the TMJ, and a recently developed dental-dedicated MRI (ddMRI) brings new possibilities to count on this technology at point-of-care.
objectivesTo evaluate the feasibility of ddMRI for the assessment of temporomandibular joint (TMJ) conditions and to compare the evaluation of bony components with that of cone-beam computed tomography (CBCT).
methodsCBCT and ddMRI images from 24 patients were independently assessed by three observers. Each TMJ side was evaluated for hard and soft tissue conditions (soft tissues assessed only with ddMRI), including flattening, cortical erosion, subcortical sclerosis, osteophyte, subcortical cyst, loose body, disc position, and joint fluid. Inter- and intra-examiner agreement and condition prevalence were calculated for each modality. Diagnoses of bone-related TMJ conditions were compared between imaging modalities using the McNemar test (α = 0.05).
resultsThe mean inter-observer agreement was 0.36 for ddMRI and 0.50 for CBCT; intra-observer agreement ranged from 0.444 to 1. The most prevalent finding was anterior disc displacement (58.3%). Bone conditions were more frequently identified on CBCT, with prevalence ranging from 2.1% (subcortical cyst) to 41.7% (flattening), compared to 0% and 31.3%, respectively, on ddMRI. In this feasibility study, no significant differences were found between CBCT and ddMRI for relevant hard tissue conditions (p > 0.05), supporting ddMRI's potential as an adjunct modality for TMJ assessment.
conclusionddMRI is a feasible imaging modality for TMJ evaluation, enabling assessment of bony and soft tissue components, while avoiding ionizing radiation, which supports its potential clinical applicability.
