Psychoacoustic characteristics of tinnitus in temporomandibular disorders: a systematic review.
Synthesis in CoDAS, 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
purposeTo describe the psychoacoustic characteristics of tinnitus in patients with temporomandibular disorders (TMD). RESEARCH STRATEGIES: A systematic review was conducted following PRISMA guidelines, with the protocol registered in PROSPERO (CRD42025649038). Searches were performed in Embase, LILACS, PubMed/MEDLINE, Scopus, Web of Science, and Google Scholar, using validated MeSH and DeCS terms. SELECTION CRITERIA: Descriptive, observational, cross-sectional, case-control, or longitudinal studies evaluating patients with TMD and tinnitus, reporting psychoacoustic parameters such as pitch and loudness, were included. Studies involving animals, single-case reports, case series, reviews, letters, editorials, or articles without original data were excluded. DATA ANALYSIS: Two reviewers independently screened titles, abstracts, and full texts, with a third reviewer resolving disagreements. Risk of bias was assessed using the JBI Critical Appraisal Tools. Data were extracted, organized, and qualitatively synthesized.
resultsA total of 271 articles were identified; after removal of duplicates and eligibility assessment, five studies were included in the synthesis. Findings indicate that tinnitus in TMD patients is predominantly unilateral, continuous, with high pitch and moderate loudness. Some patients can modulate tinnitus through mandibular or cervical movements, suggesting a somatosensory contribution. The impact on quality of life ranges from mild to moderate, even in individuals with normal hearing.
conclusionTinnitus associated with TMD shows relatively consistent psychoacoustic characteristics. However, further primary studies with larger sample sizes and robust designs are needed to confirm specific patterns and improve multidisciplinary therapeutic approaches.
