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

Abstract

Cerebral palsy (CP) is the most common motor disability in childhood, and as far as we know, there are no biometric studies that have evaluated CP and oral health (OH) on a global level. The aim of this study was to present the worldwide research trends in studies of OH in persons with CP, using bibliometric analysis. Through bibliographic information on publications about OH and CP was obtained in the PubMed database, from 1956 to 2021. The extracted data included periodical, title, year of publication, authors, citations, impact factor, key words, country, most cited publications, and study design. A total of 567 articles were published and indexed in PubMed up until 6/28/2021. The data showed a constant growth and an exponential increase in the number of publications. The articles were written in 17 different languages, and 232 (90.63%) articles were in English. Among the 111 Periodicals, Special Care in Dentistry contributed the most to scientific research with 30 articles (17.3%). Brazil (25%) and the United States (17.24%) were the countries with the highest number of publications. Observational studies were the most frequent types of articles (76.29%), followed by case reports (13.36%). It was concluded that this current network analysis indicates that although there is a significant growth in the number of publications about OH in persons with CP, it is important to increase the number of interventional randomized clinical trial studies, to include this population in high-impact oral health investigations around the world.

Worldwide panorama of bruxism and patients with disabilities: a bibliometric analysis in PubMed (1965-2021)

“…Concerning most productive authors, our findings are in agreement with previous studies (Ribeiro-Lages et al, 2021;Gutierrez et al, 2021). Santos, MTBR and Ortega, AOL were the most productive authors in the field.…”

“…There is a lack of high-level evidence in the studied topic, once case reports (28.1%), cross-sectional studies (24.54%) and literature reviews (12.72%) were the most frequent type of study designs. Similar results were observed in the literature regarding patients with disabilities (Kammer et al, 2021;Gutierrez et al, 2021) and bruxism (Ribeiro-Lages et al, 2021). The majority of observational studies related to bruxism investigated the etiology and risk or prevalence and incidence (Ribeiro-Lages et al, 2021), while for patients with disabilities epidemiology data about oral health status and prevalence of dental trauma were mentioned (Kammer et al, 2021).…”

“…Less expressive absolute numbers were also observed by Gutierrez et al in recent bibliometric analysis involving patients with cerebral palsy and dentistry (Gutierrez et al, 2021). It was verified that scientific literature raised all over the years, although, a maximum number of published papers was 17 in 2018.…”

“…It is expected that developed countries lead publications ranking, since its budget to research and new technologies are high. Incredibly, Brazil, which is a developing country (according to the definition of the United Nations) appears among the top productive countries in several scientific literature (Liu et al, 2020;Kammer et al, 2021;Ribeir-Lages et al, 2021;Gutierrez et al, 2021). This data may indicate that scientific collaborations between researchers and institutions increase the possibilities of scientific production, although it is known that scientific collaborations network between Brazil and developed countries are below the average compared to other developing countries (Cross et al, 2017).…”

“…As far as we know, there is only one published bibliometric analysis involving bruxism (Ribeiro-Lages et al, 2021) and two involving disabled people and dentistry (Kammer et a., 2021;Gutierrez et al, 2021). Publications on bruxism, especially in children and adolescents, have increased over past 20 years (Ribeiro-Lages et al, 2021).…”
