Osaka Dental University in Hirakata City, Osaka Prefecture

A former graduate student at Osaka Dental University (Hirakata City, Osaka Prefecture), co-authored with his professor, was suspected of being fraudulent in the attached image and did not respond to inquiries regarding the suspicion. On the 24th, it was found that the overseas scientific journal that published the treatise had been forcibly retracted.

The content that was withdrawn was an analysis of the surface properties of metallic titanium used in implant treatment for implanting artificial teeth, and is a co-authored paper with Professor Sadaji Okazaki, who is currently the Dean of the Graduate School of Dentistry.

The scientific journal investigated it because it was suspected that multiple images in the treatise were duplicates. I referred to a former graduate student, but did not receive a response, so I withdrew my treatise in July this year.
