Abstract

The above article, published online on 21 March 2017 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor-in-Chief, Mario Romandini; and John Wiley & Sons Ltd. The retraction has been agreed at the authors' request, following an investigation by Osaka Dental University which determined that this article contains data that the first two authors had fabricated/falsified in Figures 1 and 5, respectively. Further investigation by the publisher confirmed duplication of previously published images.
