A Bibliometric Analysis of Articles Published in Brazilian Dental Journal over 30 years

Abstract

This study assessed bibliometric characteristics of all articles published in Brazilian Dental Journal (BDJ) in its 30 years of existence (1990-2019) and factors associated with citation rates. A document search was carried out in Scopus in December, 2019 and information about the articles were exported, including citations. Type of study and main subject in each article were categorized. Number of citations was categorized in tertiles. Logistic regression models were used to assess the association between variables related to articles’ characteristics and number of citations. In 30 years, 1705 articles were published and 18507 citations received, with average 57 articles and 334 pages published yearly and 10.9 cites/doc. The most frequent types of study were laboratorial (63%), clinical (18.5%), and case reports (11%); the main subjects were dental materials (21.6%), endodontics (19.3%), and oral pathology/stomatology (13.1%). Most articles had origin in Brazil (90%), followed by USA (4.6%) and UK (1.5%). Aside from BDJ, Journal of Endodontics (3.5%) and International Endodontic Journal (2.2%) were journals that most often cited BDJ. Main origins of citations were Brazil (36.7%), USA (10.6%), and India (9%). Older articles had higher odds to be highly cited (12% increase/year), longer articles had lower odds (9% decrease/page). Narrative reviews and epidemiological studies were associated with more citations and systematic reviews with less citations. In conclusion, BDJ covered many subjects and study types in 30 years, showing increased growth in international audience. The journal may be regarded as one of the leading Brazilian journals in dentistry published in English.

Bibliometric analysis of cerebral palsy and oral health in PubMed (1956-2021)

“…In the list of the 100 most cited articles in the Journal of Dental Research (JDR), the majority of articles are from the US (52%) and the 7th country that most contributed was Brazil (Ahmad et al 2020). In the Brazilian Dental Journal (BDJ), in 30 years of publication, 90% of the articles originated in Brazil (Moraes et al 2020). After ten years of scientific production published in Acta Stomatologica Croatica, regarding the affiliation of the corresponding author, there was a higher frequency of publications of foreign origin (53.0%), Brazil had a greater contribution in these publications (25.9%) (de Araújo et al 2020).…”

“…A bibliometric characteristic of all articles published in the Brazilian Dental Journal (BDJ) in its 30 years of existence , is that the 3 authors with the most publications in the BDJ were Brazilians connected to University of São Paulo (USP, 34.5%), University of Campinas (UNICAMP, 14.7%), and Paulista State University (UNESP, 14.2%) (Moraes et al 2020).…”

“…Bibliometric studies have shown that there are differences between dental subjects, study categories, and thematic areas. In the last bibliometric reviews of dentistry journals, some specific areas stand out, such as dental materials (Moraes et al 2020), oral pathology (Bhalla and Chockattu 2020), and endodontics (Estrela Research, Society and Development, v. 10, n. 13, e299101321279, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i13.21279 3 et al 2020) but the area of special patients is not even mentioned. However, in some bibliometric reviews with a specific theme in pediatric dentistry, there was a very low percentage of articles published with a specific theme of patients with special needs (6.5%) (Adobes Martin et al 2021).…”

Scientific Production in Dentistry: The National Panorama through a Bibliometric Study of Italian Academies

“…In this way, a normalized citation index should be introduced to overcome this activity difference and reduce the potential confounding factor between the researchers, associate professors, and full professors to a more equal evaluation trend [6,12,15,30].…”

“…Moreover, the bibliometric research provides a key role for the evaluation of the scholarly chain by measuring methodologies of the scientific productivity of researchers, academies, and scientific associations [ 10 – 12 ]. An extended national bibliometric evaluation represents a valuable methodology able to create a demographic and trend analysis [ 13 – 15 ].…”
