Mapping out the bibliometric characteristics of classic articles published in a Taiwanese academic journal in dentistry: A scopus-based analysis.

Background/purpose: Since its inception, the Journal of Dental Sciences (JDS) has aimed to publish quality articles relevant to all fields in dentistry. The purpose of this study was to analyze the bibliometric characteristics and dissected associated factors correlated with citation counts of classic articles published in the JDS. Materials and method: Scopus® database was used to search the qualified articles published in JDS from 2009 to 2021. The bibliometric parameters, including journal impact factor (JIF), self-citation, study design, research field, geographic, country and institute of origin, inter-institute, inter-nation collaboration, keywords hotness and associated factors correlated with citation counts of classic articles were analyzed. Results: One hundred and eight articles from Scopus® database were eligible for analysis. The citation counts of classic articles ranged from 12 to 192, the average citation was 22.02. The most common study design was the in vitro/in vivo, followed by the cross-sectional study, and the major research field were Dental Materials. The most productive country and institute is Taiwan, and Chung Shan Medical University, respectively. The trend of inter-institute (71.03%) and inter-nation (11.22%) collaboration steadily increased since 2009. By using the multivariable linear regression model, Preventive and Community Dentistry in the research field significantly increased the citation counts. Conclusion: Despite its limitations, the escalating trends in JIFs, and JIFs without self-citations, and inter-nation and inter-institute collaboration of classic articles were noticed. Of all the dissected associated factors, Preventive and Community Dentistry in the research field significantly increased the citation counts of classic article.

The impact of smoking on peri-implant microbiota: A systematic review.

OBJECTIVES: Peri-implantitis is associated with bacterial plaque biofilms and with patients who have a history of periodontitis. Smoking is a risk factor for periodontitis, but the relationship between smoking and peri­implantitis is unclear. The aim of this systematic review was to assess evidence ascertaining the relationship between smoking and peri­implant microbiota. DATA SOURCES: An electronic search was conducted in the MEDLINE/PubMed, Embase and Scopus® databases in duplicate up to January 2023 without language restrictions. Studies were considered eligible for inclusion if they involved evaluation of the peri­implant microbiota of smokers and nonsmokers. Methodological quality was assessed with the adapted Newcastle-Ottawa scale. STUDY SELECTION: Fourteen studies were identified for inclusion in the present study, and 85.7% of the studies were defined as medium to high methodological quality. Overall, the evidence presented in this review was limited to medium to high methodological quality. The data indicates that significantly higher frequencies of anaerobic pathogens are detectable in healthy peri­implant tissues of smokers. A lower diversity of microbiota was observed in healthy peri­implant sites of smokers. In the transition from clinically healthy to a diseased status, smoking shaped a reduced peri­implant microbiota by depleting commensal and enriching pathogenic species. CONCLUSIONS: The composition of peri­implant microbiota may be influenced by smoking. More studies are needed to determine the impact of smoking on peri­implant microbiota. CLINICAL SIGNIFICANCE: In the transition from clinically healthy to a diseased status, smoking shaped a reduced peri­implant microbiota by depleting commensal and enriching pathogenic species. The composition of peri­implant microbiota may be influenced by smoking.

A bibliometric analysis of top 100 most-cited articles in dentistry with author(s) affiliated with Taiwan institutes.

BACKGROUND: Citation analysis can provide a historical perspective in the advancement of research, evolution, and areas of research. Taiwan exhibits rigorous academic and scientific activities in dentistry; however, based on its empirical contribution in research, there is no report in the literature analyzing the top-cited articles published by authors affiliated with Taiwan institutes. The purpose of this study was to analyze the citation characteristics of the top 100 most-cited articles published in dentistry with author(s) affiliated with Taiwan institutes. METHODS: The Scopus database was used to search the qualified articles with authors from Taiwan published in journals. The bibliometric parameters, including year of publication, study design, research fields, citation half-life, self-citation, institute of origin, and international collaboration were analyzed. Multivariable linear regression in generalized linear model was used to find associate factors related to trends of citation counts. RESULTS: The top 100 most-cited articles were determined by analyzing 7667 articles from the Scopus database. The steadily increasing trends were observed in the number and percentage of articles of author(s) affiliated with Taiwan institutes to the world. The most common study design was the in vitro research (55 %). The majority citation half-life is 3-5 and 6-8 years, and self-citation counts were between one to five times (n = 26). The percentage of international collaboration of these most-cited articles was 32%, and the main collaboration country was the United States. By using multivariable linear regression in the generalized linear model, the associated factors, study design, and self-citation were significantly associated with the escalating trends of citation counts. CONCLUSION: This is the first study that provides valuable information in the dentistry regarding the academic activity, and empirical contribution of author(s) affiliated with Taiwan institutes in the world. The trends of citation characteristics were significantly correlated with study design and self-citation of these articles.
