Journal Self-Citation Rates and Impact Factors in Dentistry, Oral Surgery, and Medicine: A 3-year Bibliometric Analysis


OBJECTIVES: The objective of this study was to evaluate the evolution of journal self-citation rates (SCRs) and impact factors (IFs) over time in the dental journals. MATERIALS AND METHODS: The journals listed under the category "dentistry, oral surgery, and medicine" in the Journal Citation Reports for the years 2014-2016 were screened for the following: citations and self-citations to years used in IF calculation, IF, IF without self-citations (corrected IF), SCR, and quartile of the IF distribution the journal occupied (Q1-Q4). Additional data regarding the number of issues published annually, journal's access options, and country of publication were extracted from the "Journal Profile Page." RESULTS: The median SCR significantly declined between 2014 and 2016 (13.725 [0-57.049], 12.687 [0-52.326], and 10.667 [0-53.208], respectively [P .05) were found for SCR-IF and SCR-corrected IF for all years. CONCLUSIONS: There was a statistically significant decrease in SCR during the observation period. SCR was not correlated to IF of dental journals. Subspecialty journals and journals publishing more frequently presented significantly higher SCRs. These findings suggest favorable publishing conditions and citation practices in the dental literature
