In December, The BDJ Big Impact Collection of articles was launched on the BDJ website. This collection brings together the very best of the British Dental Journal - the most cited, most accessed and most shared articles from the last 12 months (including press coverage, blogs, Twitter, Facebook and Weibo).

This content reveals the nature and quality of the BDJ - offering perspectives on clinical practice and research which resonate far beyond the UK.

The Collection is separated into three sections: most cited, most accessed and most shared. The most downloaded and most shared article is ‘Oral hygiene, mouthwash usage and cardiovascular mortality during 18.8 years of follow-up' (https://www.nature.com/articles/s41415-023-5507-4).
