A Bibliometric Analysis of the Journal of Taiwan Academy of Periodontology during 1996-2020

Abstract

Purpose: The purpose of this study was to analyze the publication trends during the past 25 years (1996-2020) in The Journal of Taiwan Academy of Periodontology (J Taiwan Periodontol). Material and Methods: The search strategy consisted of a manual search of the J Taiwan Periodontol in the library from September 1996 to December 2004, and an electronic search of the Taiwan Academy of Periodontology (TAP) website and Airiti Library for all the publications from March 2005 to December 2020. The bibliometric parameters, including year of publication, study design, scope of study, Taiwanese institute of origin, inter-in- stitute collaboration, authorship, inter-nation collaboration, and funding resource, were analyzed. Multivariable linear regression was used to analyze the publications trends. Sig- nificance was accepted when the P value was < 0.05. Results: The study design of reviews and case report/series consisted of the majority of publications, and the number of publications has been steady throughout the investigat- ed time periods (1996-2000, 2001-2005, 2006-2010, 2011-2015, 2016-2020). However, cross-sectional studies declined significantly throughout the time periods (P <0.001). Pub- lication trends have been changing, and the frequency distribution of articles published relating to implantology has been significantly arising (P <0.001). The number of articles with single author published in the J Taiwan Periodontol has been decreasing statistically (P <0.001), in other words, the number of authors participating in a study has been increasing, sometimes amounting to more than five authors (P <0.001). Meanwhile, the frequency dis- tribution of single-instituted collaboration has decreased statistically. Conclusion: This is the first study provides valuable information regarding the breadth of study design, scope of study, institute of origin, inter-institute collaboration, authorship, inter-nation collaboration, and funding resource of articles published in the J Taiwan Perio- dontol. The trends of publications have changed within the time periods.
