Alexandria, Va., USA – Today, the International and American Associations for Dental Research announced that the Journal of Dental Research (JDR) ranks #1 with a two-year Journal Impact Factor of 4.139 in the “Dentistry, Oral Surgery & Medicine” category. This news comes from the 2015 Release of Journal Citation Reports® with “Source: 2014 Web of Science™ Data”.
Journal Impact Factors are a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps to evaluate a journal’s relative importance, especially when compared with others in the same field.
“I am pleased that the JDR has advanced to #1 in our field,” said JDR Editor William Giannobile. “This news comes on the heels of the JDR’s updated look and the launch of an updated subtitle: the journal for dental, oral and craniofacial research, which emphasizes the broad scope of the Journal. This is an exciting time for the JDR and I am thankful to the scientists who continue to submit their research to the JDR for publication.”
At 0.021370 the JDR holds the highest Eigenfactor Score of journals published in the “Dentistry, Oral Surgery & Medicine” category. The Eigenfactor Score calculation is based on the number of times articles from the journal published in the past five years have been cited in the JCR year, but it also considers which journals have contributed these citations so that highly cited journals will influence the network more than lesser cited journals. References from one article in a journal to another article from the same journal are removed, so that Eigenfactor Scores are not influenced by journal self-citations.
The Journal Impact Factor was developed in the mid-1960s by Eugene Garfield, of the Institute for Scientific Information, now part of Thomson Reuters (Philadelphia, Pa., USA). It is based on the premise that the more often the articles in a particular journal are referenced by other articles, the greater the “impact” that journal has in its field. The Impact Factor is calculated by Thomson Reuters on an annual basis, and is available only through Thomson Reuters Journal Citation Reports®.
