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.

Resumo Este estudo avaliou as características bibliométricas de todos os artigos publicados no Brazilian Dental Journal (BDJ) em seus 30 anos de existência (1990-2019) e fatores associados com taxas de citação. Uma busca pelos documentos foi realizada no Scopus em Dezembro de 2019 e informações acerca dos artigos foram exportadas, incluindo citações. Tipo de estudo e principal assunto em cada artigo foram categorizados. Número de citações foi categorizado em tercis. Modelos de regressão logística foram usados para avaliar a associação entre as variáveis relacionadas às características dos artigos e o número de citações. Em 30 anos, 1705 artigos foram publicados e 18507 citações recebidas, com média de 57 artigos e 334 páginas publicadas ao ano e 10,9 citações/documento. Os tipos de estudo mais frequentes foram laboratorial (63%), clínico (18,5%) e relato de caso (11%); os principais assuntos foram materiais dentários (21,6%), endodontia (19,3%) e patologia oral/estomatologia (13,1%).

Prevalence of risk factors for denture stomatitis in complete denture wearers

Aim: The prevalence of denture stomatitis and the relationship with its risk factors was evaluated via secondary data from 62 complete denture (CD) wearers, between 2015 and 2017. Methods: The data was stored in an Excel database and was analyzed using the statistics software STATA/SE 12.0. A descriptive analysis was performed taking into account a categorization of the clinical variables according to risk factor in 4 domains: CD usage, systemic health, hygiene habits, and usage habits. The association amongst the denture stomatitis and risk factors variables was tested by the Chi-square test and the results were statistically significant at p-values <0.05. Results: The CD wearers participants were composed by a majority of elderly (80.64%) and women (72.78%); with 45.16% having been using the current denture for more than 10 years and another 74.19% related a continuous usage. Diabetes and hypertension were related by 83.87% and 67.74%, respectively, with 87.10% using medication. Although 75.80% reported cleaning their dentures 3 times per day or more, and 59.68% considered their oral hygiene very good, 50% of the complete dentures showed dirtiness and clinical signs of Denture Stomatitis were present in 30.64% of the patients. Despite of the evaluated sample shows many risk factors for the development of the disease, an association between the variables was not observed. Conclusion: Considering the high prevalence of the disease in the studied sample, preventive and educational measures on denture usage and hygiene must be reinforced in order to maintain the oral health of the edentulous patients
