Background and Objectives

This global bibliometric review aimed to investigate trends in publications relating to tinnitus and TMD.


A search was performed in eight databases (June/2022), by independent researchers with relevant keywords about tinnitus and TMD, without restriction of date or language. Original research or case report/series evaluating prevalence, association and risk related to tinnitus and TMD were included. Independent examiners selected studies by title and abstract and performed data extraction. Data about publication and researchers, study population, objective, study design and diagnostic criteria for tinnitus and TMD were exported to VintagePoint® for bibliometric analyses. Data about the direct association between tinnitus and TMD were extracted.


One hundred and seventeen articles from 25 countries were included, most observational (68.4%) and evaluating association (N = 60; 44.8%). Among the 60 studies of association, 22 (36.6%) presented results of a direct association between the presence/absence of tinnitus and the presence/absence of TMD. Brazil (19.5%) and the United States (12.7%) were the countries with the most publications, and Dentistry (48.6%) was the main publication area. A growth in publications in Dentistry was observed in the past 30 years and in the past 10 years in Medicine. Half of the studies included the elderly population (50.2%). The main diagnostic criterion for both tinnitus (37.8%) and TMD (28%) was general questionnaires and/or self‐report.


There is a growing trend in publications relating to tinnitus and TMD, especially in Dentistry, with a predominance of observational and association studies in the elderly population using questionnaires and/or self‐report. More research with robust diagnostic methods and other study designs should be encouraged in the future.
