Bibliometric Study of the National Scientific Production of All Peruvian Schools of Dentistry in Scopus

Trends in scientific publication among dental students at a private Peruvian university: a seven-year characterization

BACKGROUND

For health science students, publishing in scientific journals is a significant milestone that can positively impact their professional careers, providing recognition and credibility within the academic and professional community. However, despite the apparent increase in scientific production among undergraduate dental students in Latin America and the Caribbean, it remains low compared to other regions. The study aimed to determine the frequency of publication in scientific journals of the documents to obtain the professional title of dental surgeon by undergraduate dental students at a private Peruvian university over seven years.

METHODS

This cross-sectional study considered all records of theses required for the professional title of dental surgeon from the Faculty of Dentistry at a private Peruvian university, as published in its institutional repository between 2017 and 2023. The main variable of the study was publication in scientific journals. In contrast, the year of formal submission of the document to obtain the professional title of dental surgeon, the type of document, the modality of obtaining the professional title, the area of dental specialty according to the American Dental Association, the year of publication, international indexing, impact factor (IF), and journal's quartile ranking were considered as covariates. Descriptive analysis was conducted to obtain absolute and relative frequencies.

RESULTS

Between 2017 and 2023, 246 documents for the professional title of dental surgeon were published in the institutional repository of a Peruvian university, of which 23 were subsequently published in scientific journals. Of these, 20 (86.96%) were published in internationally indexed scientific journals, 1 (5.00%) was published in journals with an IF ≥ 2, and 2 (10.00%) were published in Q2 category journals.

CONCLUSIONS

The seven-year analysis reveals significant challenges in converting undergraduate dental research at a Peruvian university into published scientific literature, with low rates of research documents achieving publication in scientific journals.

Evolution of scientific productivity in dentistry: tracking postgraduate publications at a Peruvian university

Introduction

Scientific production indicators help universities quantitatively and qualitatively assess postgraduate students' publications and contribute to the optimization of research processes. This study aimed to determine the frequency of publication in scientific journals of the documents submitted by postgraduate dentistry students to obtain a second professional specialty title and master's and doctoral degrees at a private Peruvian university over seven years.

Materials and methods

A cross-sectional study was conducted, considering the population and the records of documents submitted to obtain the second professional specialty title and the master's and doctoral degrees in dentistry at a private Peruvian university, published in its institutional repository from 2017 to 2023. The primary outcome was publication in scientific journals, and the covariates were the year of formal submission of the document, postgraduate level, modality of document preparation, area of dentistry specialty according to the American Dental Association, year of publication, international indexing, impact factor (IF), and quartile. A descriptive analysis was performed to obtain absolute and relative frequencies.

Results

Between 2017 and 2023, out of 322 documents submitted to receive the second professional specialty title and the master's and doctoral degrees published in the institutional repository, 72 were published in scientific journals. Of these, 81.94% (n = 59) were published in an internationally indexed scientific journal, with 13.56% (n = 8) published in a journal with an IF≥2 and 10.18% (n = 6) in a Q1 category journal.

Discussion

In low-income countries, the nexus between education and scientific output is multifaceted. While education serves as a critical catalyst, numerous challenges constrain the expansion of research. These nations contribute a mere 2% of global scientific production, despite confronting significant public health issues, underscoring a notable discrepancy between educational attainment and research productivity. The disparities in scientific output across universities in Latin America, Asia, and Europe are shaped by a confluence of cultural and economic determinants. In conclusion, 22.36% of the documents submitted to obtain the second professional specialty title and the master's and doctoral degrees by postgraduate dentistry students at a private Peruvian university over seven years were published in scientific journals.

Factors associated with the perception of university social responsibility among dental students from two universities in the Peruvian capital: a multivariable regression analysis

Students play a key role in university social responsibility (USR), as they are the protagonists of change and the fundamental axis in the teaching-learning process. This study aims to assess the factors associated with the perception of university social responsibility among dental students from two universities in the Peruvian capital. This analytical cross-sectional study assessed 754 students from two Peruvian universities between May and July 2023. The study utilized a validated 51-item questionnaire to assess sociodemographic factors and dental students' perception of USR. A Poisson regression model with robust variance and prevalence ratio (PR) was used to assess the influence of variables such as age, sex, marital status, type of university, academic year, and awareness of taking subjects related to USR. The significance was set at p < 0.05. The perception of USR was rated as poor, fair, and good by 16%, 67%, and 17% of the participants, respectively. According to the study, dental students from public universities were 68% more likely to perceive their USR education as poor than those from private universities (APR = 1.68, 95% CI: 1.06-2.66), and those who were aware of taking MSR-related courses were 37% less likely to perceive their USR education as poor (APR = 0.63, 95% CI: 0.40-0.98). Similarly, dental students attending public universities were 2.28 times more likely to perceive poor organizational management in USR compared to their counterparts at private universities (APR = 2.28, 95% CI: 1.51-3.44). Additionally, students in their first and second academic years were 62% and 57% less likely to perceive poor organizational management in USR compared to those in their sixth year (APR = 0.38, 95% CI: 0.19-0.79 and APR = 0.43, 95% CI: 0.20-0.95; respectively). Furthermore, students from public universities were 2.31 times more likely to perceive social participation in USR poorly compared to their counterparts from private universities (APR = 2.31, 95% CI: 1.63-3.26). Lastly, it was observed that students from public universities were 2.51 times more likely to have a poor overall perception of USR compared to students from private universities (APR = 2.51, 95% CI: 1.67-3.78). Acknowledging the diverse contexts and challenges inherent in public and private institutions, it can be concluded that more than half of the dental students had a fair perception of USR. Additionally, attending a public university was found to be a risk factor for having a poor perception of USR. However, taking a course related to USR and being in the early years of the program were identified as protective factors against a poor perception of organizational training and management in USR. It is recommended that students be involved in USR activities, including the Sustainable Development Goals, from the first years of their university education, especially in public universities.

Characteristics and quality of systematic reviews led by Peruvian authors: A scoping review

Background

Systematic reviews (SRs) worldwide suffer from methodological deficiencies, potentially biasing intervention decisions, and Peruvian SRs are no exception. Evaluating SRs led by Peruvian researchers is a crucial step to enhance quality and transparency in decision-making and to identify topics where SRs are either scarce or prioritized for research.

Objective

To describe the characteristics and assess the methodological quality of SRs with Peruvian first authors.

Methods

We conducted a scoping review within the Scopus database on January 5, 2023. We aimed to identify published SRs of interventions in which the first author had a Peruvian affiliation, published between 2013 and 2022. We evaluated the methodological quality of these SRs using the AMSTAR 2 tool. We assessed the factors associated with the AMSTAR 2 score using adjusted mean differences (aMD), including their 95 % confidence intervals (95 % CI).

Results

We identified 95 eligible SRs, with a clear upward trend. SRs were primarily published in Q1 (43.2 %) and Q2 (23.2 %) journals, predominantly affiliated with institutions in Lima (90.5 %). Areas like infectious diseases (20.0 %) and dentistry (18.9 %) were most frequent. AMSTAR 2 assessments highlighted deficiencies, with few SRs reporting prior protocols (37.9 %), comprehensive search strategies (23.2 %), explanations for excluded studies (20.0 %), adequate descriptions of included studies (38.3 %), or funding sources (19.1 %). Notably, SRs in Q4 journals (aMD: -19.7, 95 % CI: -33.8 to -5.5) and those on surgical interventions (aMD: -22.6, 95 % CI: -34.7 to -10.4) had lower AMSTAR 2 scores.

Conclusions

Although Peruvian-led SRs are increasingly being published, critical deficiencies are common, especially in reporting protocols, search strategies, study descriptions, and funding sources. Addressing these gaps is pivotal for enhancing the credibility and utility of these SRs in informing decision-making.

Bibliometric analysis of the worldwide scientific production on COVID-19 infection and cerebrovascular disease

Objective

To identify the worldwide bibliometric characteristics of research on SARS-CoV-2 infection and cerebrovascular disease.

Methods

A retrospective, descriptive, and bibliometric study was performed. We analyzed 1834 publications about COVID-19 and cerebrovascular disease from the Scopus database considering the time since the beginning of the pandemic between 2019 and 2020. Bibliometric indicators were evaluated such as number of citations, citations per publication by authors, countries, journals, and collaborations at national, international, institutional, and impact levels according to Cite Score Quartile and h-index metrics. All analysis was performed using SciVal software.

Results

The highest percentage of articles corresponded to universities in the United States, including Harvard and New York with 59 and 20 publications, respectively, and the University of Toronto in Canada with 22 publications. In relation to citation indicators, journals such as Stroke and Journal Stroke and Cerebrovascular diseases obtained 1971 and 561 citations, respectively. Regarding collaboration indicators, the national collaboration index was 39.4% and the institutional collaboration index was 31.1%. Finally, neurology, cardiovascular medicine, and cardiology and surgery were the subject areas with the highest research results, with 424, 217, and 128 studies, respectively.

Conclusion

It was observed that the United States was the country with the highest scientific production on COVID-19 and cerebrovascular disease in the year 2020 in the different health areas; however, more research is still needed worldwide for a better analysis of the bibliometric indicators on the subject.

The aim of this study, therefore, was to analyze bibliometrically the impact, trend, and characteristics of scientific production related to the mental health of health professionals during the COVID-19 pandemic.

MATERIALS AND METHODS

A bibliometric analysis of the scientific production on the mental health of health professionals and COVID-19 in Scopus from December 2019 to December 2021 was performed. An advanced search was designed using Boolean operators in Scopus and applied in April 2022. The metadata was entered into Microsoft Excel for the elaboration of the tables, SciVal to obtain the bibliometric indicators, and VosViewer to plot collaborative networks.

RESULTS

A total of 1393 manuscripts, 1007 of which met the eligibility criteria, were found on the mental health of health workers and COVID-19. The country with the highest academic production was the United States and Harvard University with 27 manuscripts as the most productive institution. The scientific journal with the highest scientific production was the International Journal of Environmental Research and Public Health with 138 manuscripts and 1580 citations, and the author with the most citations per publication was Carnnasi Claudia with 69.8.

CONCLUSION

The countries with the highest economic income occupy the first places in scientific production on the mental health of health workers during the COVID-19 pandemic, with the United States as the leader. There is a gap in the scientific knowledge on the mental health of healthcare workers during the COVID-19 pandemic in middle- and low-income countries.

Scientometric evaluation of trends and global characteristics of published research on occupational public health

The objective of this scientometric study was to assess the global trends and characteristics of published occupational health research from 2016 to 2020. The SciVal tool (Elsevier) was used to perform the corresponding bibliometric analyses such as the Field-Weighted Citation Impact (FWCI), Source Normalized Impact per Paper (SNIP), CiteScore, and SCImago Journal Rank (SJR). Most of the manuscripts (46.5%) had national collaboration, with an average of 6.1 citations per paper. However, only 71 manuscripts (5.4%) presented single authorship (without collaboration). It was found that 486 manuscripts related to occupational health were published in Q2 journals (top 26-50%). Scientific publications on occupational health have increased remarkably worldwide, especially in Europe, and have mainly been published in Q1 and Q2 journals with a total of 292 and 289 scientific manuscripts in 2019 and 2020, respectively.

Papers with international collaboration were the most cited. Keyword analysis showed that the terms Parkinson Disease, Disease, and Intestine Flora were the most frequent.

Conclusion

The number of papers on Parkinson's disease and gut microbiota has been increasing; however, high-quality journals maintain the same high publication rate. International collaboration from high-income countries played an important role in the impact generated by the publications.

Scholarly Output in Peruvian National Dentistry according to Gender Disparity: A 10-Year Bibliometric Study

Objective. To evaluate Peruvian scientific publications in dentistry according to sex disparity (2011-2020). Methods. This was a retrospective bibliometric study. The unit of analysis was made up of Peruvian dentistry publications indexed in the Scopus database during the last 10 years. Records with metadata (410) corresponding to the period 2011-2020 were downloaded and standardized and refined by analyzing the metadata. The search strategy was developed based on the individual profiles of each Peruvian institution that has a dental school or college. It was evaluated according to the AF-ID of each institution in the Scopus database. In addition, the information provided by the Scopus SciVal tool was used. Finally, publications, impact, and collaboration indicators were used, such as total number per document, per author, average of citations, $h$ -index, collaboration rate, number of institutions, the Source Normalized Impact per Paper indicator, the CiteScore, and the Scopus Field-Weighted Citation Impact. Results. The greatest increase was evident in 2018, with 2019 and 2020 being the maximum peak of scientific publication growth. However, sustained growth has not been evidenced in relation to the female sex. The analysis of coauthorship by the authors revealed four large clusters, of which the first three were represented by male researchers, such as Arriola-Guillen L., Mayta-Tovalino F., and Mendoza-Azpur G., and one by a female, Guerrero María E. Evaluating the national scientific publication in dentistry according to the CiteScore, it was found that most of the publications (145) from Peru were published in Q4 journals, although 90 manuscripts were published in Q1 journals. Conclusions. The Peruvian national dental publication in the last 10 years was mainly supported by male dentists, which invites us to reflect on the need to equalize opportunities so that female researchers can also reduce these gaps.

Likewise, the United States is the country with the most publications, authors, and universities on the subject. Greater efforts are still lacking from all countries in the world to reach the quantity and quality of production of the United States.

Bibliometric Analyses of Global Scholarly Output in Dentistry Related to COVID-19

Objective

The aim of this study was to evaluate the bibliometric profile of dental scientific production related to coronavirus disease-2019 (COVID-19) in Scopus (2019-2020).

Materials and Methods

This was a descriptive, observational, comparative, and retrospective study. All manuscripts on COVID-19 in dentistry were published between December 2019 and December 2020. The variables were measured objectively through Scopus (SciVal). For the extraction of the manuscripts, the following keywords were used: "Covid-19" and "Dentistry" with its multiple MeSH terms using the Boolean operators "OR" and "AND". On June 14, 2021, 843 manuscripts corresponding to the period January 2019 to December 2020 were downloaded, normalized, and refined through metadata analysis.

Results

The largest number of manuscripts was published in the International Journal of Current Research and Review, Oral Oncology, Oral Diseases, British Dental Journal, and Journal of Dental Education with 54, 50, 49, 48, and 44 manuscripts, respectively. These are the most productive indexed scientific journals on COVID-19. The most productive institutions were Saveetha University, Universidade de São Paulo, and King's College London, with 42, 33, and 27 manuscripts, respectively. In 2019, there were only two scientific publications on COVID-19. In 2020, the largest amount, 228 manuscripts, were published in Q1 journals, followed by 210 manuscripts in Q3 journals, and only 194 manuscripts were published in Q4 journals.

Conclusions

Currently, there is a notable increase in global academic production in Scopus on the impact of COVID-19 in dentistry, whereas Brazil is the only South American country with three highly productive universities.
