Mapping the research landscape on temporomandibular disorders and orthodontics treatment: A bibliometric analysis.

BACKGROUND

Temporomandibular disorders (TMD) and orthodontic treatment are significant areas within dental and maxillofacial research. However, comprehensive bibliometric analyses highlighting global trends and collaboration networks are lacking.

OBJECTIVE(S): This study aims to systematically map the publication landscape, identify prevailing research trends, highlight influential authors and institutions, and illuminate emerging topics in TMD and orthodontic research.

METHODS

Publications concerning TMD and orthodontic treatment from 2000 to 2024 were retrieved from the Web of Science Core Collection. A bibliometric analysis was conducted using VOSviewer, CiteSpace, and R to evaluate co-authorship networks, institutional collaborations, and keyword co-occurrence patterns.

RESULTS

A total of 871 publications were identified, with an average annual growth rate of 4.4 %. Contributions came from 47 countries and involved 3,463 authors, with the USA and Japan leading in citations. Notable institutions included Kyung Hee University and Baylor University. Key journals included the American Journal of Orthodontics and Dentofacial Orthopedics and the Journal of Oral and Maxillofacial Surgery. Frequently occurring keywords were "temporomandibular-joint," "orthognathic surgery," and "orthodontic treatment," indicating essential research foci. Emerging trends highlighted advancements in surgical techniques and technological innovations in orthodontics.

CONCLUSION

This bibliometric analysis offers valuable insights into global research trends and hotspots in TMD and orthodontic treatment, emphasizing the collaborative nature of the field and illuminating emerging areas for future investigation.
