Journal's correction note:
Research article Br Dent J 2022; DOI: 10.1038/s41415-022-4926-y.
When this article was originally published, DCBO was used throughout to denote 'Dental Check by One' but should have read DCBy1. This has since been corrected.
In addition, an incorrect version of Figure 3 was displayed. The correct figure is presented here, in which the x-axis has been updated.
