Objectives:
A systematic bibliometric analysis of the structure of knowledge was performed to investigate the co-word analysis, the co-citation analysis, and the social network analysis regarding complex oral sensitivity disorder (COSD).
Methods:
Web of Science database from 1985 to 2018 was systematically searched to identify all relevant articles using the MeSH terms "complex oral sensitivity disorder" and all synonyms used in the literature. We included original articles, review articles, letters to the editor, and book chapters in the English language and in 27 different ISI categories of medical sciences. Several bibliometric indicators were used.
Results:
The co-word analysis identified 741 KeyWords Plus (KWP) grouped into 4 different clusters. The terms "pain," "management," "prevalence," and "efficacy" reached the highest centrality, whereas the top 10 KWP had a frequency of 7%-29% in 443 articles. Over a period of 32 years, a complex thematic evolution occurred, going from 2 to 6 different themes, and the KWP migration rate from one cluster to another ranged from 11% to 100%. The co-citation network analysis based on the complete reference list (5932 references) of 443 articles identified only 2 clusters for journals, authors, and articles. The most prominent co-cited journal was "Oral Surgery Oral Medicine Oral Pathology" (centrality: 171.75), the most co-cited author was "Grushka M" (centrality: 330.95), and the most co-cited article was "Grushka M. Oral Surg Oral Med Oral Pathol (1987) 63:30-36" (centrality: 269.79). On the other hand, the direct citation network revealed that "Scala A et al, 2003" reached both the highest global citation score (GCS = 231) and local citation score (LCS = 161). Lastly, the social network analysis revealed an isolated collaboration among groups of authors, or countries or institutions. The worldwide collaboration analysis indicated that United States-Israel and United Kingdom-Italy were the most collaborative countries.
Conclusions:
The structure of knowledge of publications on COSD revealed that research in this field has been dominated by few core topics and a limited collaboration among authors and institutions from different countries. More multicenter studies on COSD are warranted in the near future when launching new projects.
