Brazilian Articles in Top-Tier Dental Journals and Influence of International Collaboration on Citation Rates

Abstract

This study investigated the presence of co-authorship from Brazil in articles published in top-tier dental journals and analyzed the influence of international collaboration, article type (original research or review), and funding on citation rates. Articles published between 2015 and 2017 in 38 selected journals from 14 dental subareas were screened in Scopus. Bibliographic information, citation counts, and funding details were recorded for all articles (N=15619). Collaboration with other top-10 publishing countries in dentistry was registered. Annual citations averages (ACA) were calculated. A linear regression model assessed differences in ACA between subareas. Multilevel linear regression models evaluated the influence of article type, funding, and presence of international collaboration in ACA. Brazil was a frequent co-author of articles published in the period (top 3: USA=25.5%; Brazil=13.8%; Germany=9.2%) and the country with most publications in two subareas. The subjects with the biggest share of Brazil are Operative Dentistry/Cariology, Dental Materials, and Endodontics. Brazil was second in total citations, but fifth in citation averages per article. From the total of 2155 articles co-authored by Brazil, 74.8% had no co-authorship from other top-10 publishing countries. USA (17.8%), Italy (4.2%), and UK (3.2%) were the main co-author countries, but the main collaboration country varied between subjects. Implantology and Dental Materials were the subjects with most international co-authorship. Review articles and articles with international collaboration were associated with increased citation rates, whereas the presence of study funding did not influence the citations.

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

“…The main subject addressed by the article also was categorized: basic science (e.g. cell biology, genetics, microbiology), dental education, dental materials, endodontics, implantology, operative dentistry/ cariology, oral and maxillofacial surgery, oral pathology/ stomatology, oral radiology, orthodontics, pediatric dentistry, periodontology, prosthodontics/occlusion, public health/epidemiology, or other (3). Additional information regarding all articles published during the 30 years of BDJ were obtained in Scopus: top publishing authors and institutions, main funding sponsors, top cited articles, and country of origin of articles and citations.…”

“…In contrast, 10 international dental journals from Brazil were present in the list in 2018, with H-indexes varying from 2 to 48 (BDJ is highest). The remarkable increase in international science output from Brazil in the last two decades has been discussed before (2,3) and there are many factors and variables involved in the process. Concurrently, BDJ has experienced many changes as a journal since its first issue in 1990, including increase in subjects covered and types of study published, growth in international audience and in number of articles published yearly.…”

La producción científica de la revista Acta Colombiana de Psicología: Análisis descriptivo y bibliométrico del período 2015-2019

“…De otra parte, los índices de colaboración empleados en el presente estudio evidencian un incremento importante, cuestión que se potencia con el acceso abierto (Gabrielle-Breugelmans et al, 2018) y que se asocia a un alza de las citas en el caso de la colaboración internacional (Gonçalves et al, 2019). La concentración temática de la revista se aproxima a un nivel medio, aspecto que es importante mantener.…”

Produção científica de docentes de uma universidade estadual pública: o caso da Universidade Estadual da Paraíba

“…Dentre os programas de pós-graduação da UEPB, Odontologia destacou-se pelo maior número de artigos publicados. Essa mesma tendencia tem sido registrada em nível Nacional, uma vez que desde 2006 a produção da área de odontologia vem se destacando quando comparada a outros países (Gonçalves et al 2019). Segundo estes autores, o Brasil aparece na segunda posição do ranking dos países que mais produziram artigos científicos indexados na área de odontologia, atrás apenas dos Estados Unidos.…”
