Evaluating global research trends in special needs dentistry: A systematic bibliometrix analysis
Open accessAbstract
Objectives: Special needs dentistry (SND) is a vast and fragmented field of study. This comprehensive bibliometric analysis aimed to evaluate the scope of SND, including the existing knowledge base, distribution structure, quantitative relationships, and research trends. Material and Methods: A systematic search was conducted on March 10, 2022, using the Web of Science Core Collection database, covering the period from 1985 to 2021, focusing on studies reporting on special needs populations in a dentally relevant context. Records were title‐screened and analyzed for key bibliometric indicators. Results: Among 48,374 articles, 13,869 underwent bibliometric analysis. Peak SND research occurred during 1985–1997. United States led in productivity, trailed by Brazil and Japan. University of Sao Paulo excelled in Brazil, University of Washington and University of North Carolina in the United States. The Journal of Dental Research was the most productive source of research and also had the highest number of citations, followed by Community Dentistry and Oral Epidemiology. Keyword analysis revealed that “elderly”, “caries”, and “epidemiology” were the most commonly used author keywords. Conclusions: This study represents the first bibliometric analysis of SND literature. It emphasizes the need for increased collaboration between institutions and authors. Furthermore, it suggests focusing on research input from non‐dental disciplines and populations with rarer intellectual or developmental conditions.

India accounted for less than 5% of global dental publications in 2022, with a substantial proportion published in non-indexed or low-impact journals.
“A bibliometric analysis from the Scopus database indicates that India accounted for less than 5% of global Dental publications in 2022, with a substantial proportion published in non indexed or low-impact journals (5).”
From Research Publication Challenges Faced by Dentists in India: A Narrative Review of Multilevel Barriers (2026) · cites this paper as [5]
Table 2 in Results, ‘Countries, institutions, and departmental productivity’ (page unavailable), reports India at 620 articles (4.3%), but this is for special needs dentistry from 1985–2021, not all dental publications in 2022. The Discussion says the search used Web of Science, not Scopus, and did not assess the quality of individual studies; the paper does not substantiate the claim about a substantial proportion appearing in non-indexed or low-impact journals.

The Introduction describes a bibliometric analysis of special needs dentistry, and the Discussion addresses gaps between research and clinical practice. Neither section discusses Community-based Participatory Research or community involvement throughout the research process.

The Results section on countries, institutions, and departmental productivity reports publication counts, while the Discussion mentions advocacy for changes to education, policies, and research. Neither passage says that institutions implemented reforms or that such reforms caused an increase in research output (searched: reforms, institutional reforms, increased research output).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
