Anterior Disc Displacement in a Young Patient With Stage II Osteoarthritis: Diagnostic and Therapeutic Approach. A Case Report.
Article in Case reports in dentistry, 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
Anterior disc displacement without reduction can cause acute functional limitations and may coexist with inflammatory and early degenerative changes in young patients. We report a 22-year-old woman with right preauricular pain, a closed lock, and a maximum unassisted interincisal opening of 19 mm. Cone-beam computed tomography and magnetic resonance imaging confirmed Stage II osteoarthritis of the right temporomandibular joint, right anterior disc displacement without reduction with limited opening, left anterior disc displacement with reduction, and bilateral joint effusion consistent with synovitis. Hormonal testing showed values discordant with the expected follicular-phase ranges after recent discontinuation of injectable contraception; this finding was interpreted as a potential modulatory factor rather than evidence of causation. Management included bilateral temporomandibular joint arthrocentesis, intra-articular administration of betamethasone and sodium hyaluronate, a stabilization splint, pharmacological therapy, physical therapy, and behavioral modification. Pain decreased markedly within the first week. At the 3-month follow-up, maximum unassisted mouth opening was 42 mm, with a straight opening path, pain-free function, and resolution of the right masseter spasm. This case highlights the value of early imaging-based diagnosis and individualized multimodal management in young patients with concomitant mechanical, inflammatory, and early degenerative temporomandibular joint changes.
