Are highly ranked dental journals at risk of editorial bias? An examination of information on the reporting of peer-review practices.

The objective of the present study was to assess how clearly and transparently reported are the editorial policies of highly ranked dental journals regarding the handling of submitted manuscripts. A total of 92 dental journals classified by impact factor had their websites scrutinized between 22 July and 6 September 2021 for all information on their policies regarding the handling of submitted manuscripts by editors. The information included items that could indicate potential risk of editorial bias. A total of 49 (53.3%) of the selected journals allowed the submission of all types of manuscripts, while 26 (28.3%) journals did not allow some types of manuscripts to be submitted (some manuscripts are only commissioned). The criteria for the acceptance of submitted manuscripts were clearly reported in eight (8.7%) journals, and only one reported the criteria in a hierarchical fashion. Sixteen (17.4%) journals reported a policy for handling the submitted manuscript when an editor was the author of the manuscript. Nine (9.8%) journals reported the possibility of a rebuttal letter by authors after manuscript rejection, but for most (62%) journals this information was not reported. The reporting of editorial policies regarding the peer-review process in highly ranked dental journals should be improved.
