This article has been retracted at the request of the Editorial Board.

The Editorial Board consulted with the KAMJE (Korean Association of Medical Journal Editors) about ‘Imalas’ matter of the publication and concluded as following:

The Paper A1 is an article on the study of pain, inflammation and formation of granulation tissue using platelet rich fibrin (PRF) for dry socket treatment after tooth extraction. This study was conducted on 100 patients at Teerthankar Mahaveer Dental College and Research Center, Moradabad, from September 2014 to March 2016.

The Paper B2 is a research based on the same conditions as Paper A1. This study was conducted on 100 patients using PRF and 100 patients using zinc oxide eugenol, from August 2014 to December 2017. The study was held at the Kothiwal Dental College and Research Centre (KDCRC), Moradabad.

The clinical factors studied in above two articles are the same, and the pain scale in Fig. 3 in Paper A1 is almost identical to the Fig. 2, Group A in Paper B2; and Fig. 5 in Paper A1 is also same as Fig. 4, Group A in Paper B2. Both papers are judged to have the overlapping publication in the similar period and the patient, and it is considered intentional not to cite Paper A1 in Paper B2. Therefore, Paper B2 is believed to be a significant double publication.

For this reason, the Editorial Board decided to retracted this article and sincerely apologize for any inconvenience this may have caused.
