The British Dental Journal's Journal Impact Factor (JIF) has this year increased from 1.626 to 2.727, meaning that the BDJ now ranks 48/92 in the Dentistry, Oral Surgery and Medicine category. This increase has moved the BDJ up to the next ranking quartile, into Q3.

The annual JIF is a ratio between citations and recent citable items published. The 2021 JIFs were therefore calculated by dividing the number of citations each journal received in 2021 to the source items published in that journal during 2019 and 2020. The annual JIF is released in summer each year.

Journal performance is measured in several ways, including numbers of citations and downloads. Clarivate's Journal Citation Reports generates the JIF report and other citation data for more than 12,000 journals and conference proceedings in the sciences and social sciences indexed in Web of Science. Alongside an increase in the JIF, the BDJ also saw increases in other citation metrics, including the Journal Citation Indicator, which is a measure of citation performance that is normalised to the category the journal is indexed within, therefore allowing journals to be more easily compared between categories.

Commenting on the announcement of the BDJ's latest Impact Factor, Rebecca Shreeve, Executive Publisher, Medicine and Life Sciences at Springer Nature, said: 'This is a fantastic achievement, only made possible by all the hard work that has gone into this journal, so huge congratulations to everyone involved!'
