Background & Aims
Despite the recognized interplay between bruxism and temporomandibular disorders, a systematic exploration of their academic discourse remains limited. By analyzing the evolution, trends, and gaps in published research, this study seeks to provide a nuanced understanding of how the scientific community perceives and addresses the correlation between bruxism, in its various forms, and TMD, particularly its painful manifestations. The goal is to elucidate the depth and breadth of existing research, thereby informing future studies and clinical approaches in this vital area of dental and orofacial health.
Methods
Employing a comprehensive bibliometric analysis, we systematically reviewed literature from the Web of Science Core Collection. The analysis included articles from 1992 to 2023, utilizing advanced tools like Biblioshiny and VOSviewer for data visualization. Key parameters like publication year, citations, and authorship were considered. Special attention was given to authors-keywords co-occurrence and semantic mapping to decipher the conceptual framework of the study field.
Results
Our analysis included 291 studies published between 1992 and 2023 across 120 different sources, witnessing an average annual increase rate in publications of 11.94%. These articles involved 1,047 authors, with 21.65% international co-authorship, and an average of 4.74 co-authors per document. On average, articles were 9.26 years old with 21.22 citations each. A significant rise in annual scientific production was noted post-2012. “Journal of Oral Rehabilitation” emerged as the most significant journal, accounting for 15.8% of the publications. The authors hailed from 40 different countries, with Brazil, Turkey, and the United States being the top contributors. Analysis of bruxism types – sleep and awake – revealed stronger connections in sleep bruxism, with awake bruxism gaining focus post-2020. Thematic evolution, analyzed through different periods, showed an initial focus on muscular activity shifting towards mental health issues like anxiety and depression in recent years.
Conclusions
Our findings underscore the complexity and multidisciplinary nature of research on bruxism and TMD. The study provides a comprehensive overview of the academic landscape, highlighting the need for more focused research on awake bruxism and the psychological dimensions of these conditions. The evolving nature of research themes suggests a paradigm shift towards a more holistic understanding of bruxism and TMD.
