Since April, the Romanian Journal of Internal Medicine (RJIM) retracted nine papers (eight for plagiarism, one for duplication); four of these were co-authored by Manole Cojocaru, a researcher at the Titu Maiorescu University (TMU) in Bucharest, Romania. Subsequently, the journal has banned Cojocaru from submitting manuscripts, and has also informed the ethics committee at his institution.
The retraction for “Chewing ability in an adult Chinese population” appeared in Clinical Oral Investigations in 2012, but we’re sharing it with you now because the notice contains some remarkable language:
This article has been withdrawn due to wrong content with serious consequences such as danger to people’s health.
Last author Nico H.J. Creugers, who works at Radboud University Medical Center in the Netherlands, told us:
Following a “thorough investigation,” the Journal of Conservative Dentistry (JCD) has retracted a paper after concluding that the first author stole the text from another paper when peer reviewing it for a different journal.
The JCD decided that the 2013 paper about white spot lesions and inhibiting the growth of the bacteria Streptococcus mutans in the mouth is a “verbatim copy” of a paper that was rejected by the International Journal of Paediatric Dentistry in 2012 but published by The Journal of Clinical Pediatric Dentistry in 2014.
The first author denied the charges, saying she had finished the paper before reviewing the other, which she suggested rejecting.
We’ve stumbled upon a trio of retractions published in August, 2013 from BMJ Case Reports for “redundant publication” to a group of researchers based in India.
Editors found that the reports, which were published between 2012 and 2013, had considerable “overlaps” with articles that had been published in other journals. Although one of the retracted authors was also an author on one of the overlapping articles, the rest of the authors have no obvious connection to the previous work.
The authors of the three retracted papers are based at the Modern Dental College and Research Centre in India.
One retracted paper, “A rare occurrence of peripheral ossifying fibroma in the first decade of life and its management,” described the case of a 10 year-old girl with a lesion growing on her gums. The notice reads:
A case report that detailed the removal of a cyst from the side of a young woman’s face has been retracted for plagiarizing text from a similar case report published two years earlier.
Contemporary Clinical Dentistry posted the notice on July 31. Parts of the 2014 report were “directly copied” from a report published in 2012 by the Journal of Oral and Maxillofacial Pathology. Neither of the reports share authors in common.
The notice reads:
Aeronautic dentistry seems like a fairly unique field, but a review article about keeping teeth healthy in outer space has been retracted from the International Journal of Stomatology & Occlusion Medicine for not being quite unique enough.
“Aeronautic dentistry: an upcoming branch,” a review article, appears to have lifted pieces of other works “verbatim and without citation,” according to a representative from the journal’s publisher.
According to the first author, any plagiarism was purely accidental:
The amount of material which seems to be plagiarised was not done intentionally.
A former dental researcher at the University of Maryland, Baltimore, has lost a 2009 paper in the journal Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology for fabricating his data on an NIH-funded study.
The researcher, Mark A. Scheper, is not identified in the retraction notice as the person implicated in the university investigation. However, one of his co-authors confirmed his involvement. Scheper died in January 2014 at age 45 of natural causes, according to the Maryland State Medical Examiner.
The article was titled “The oncogenic effects of constitutive Stat3 signaling in salivary gland cancer cells are mediated by survivin and modulated by the NSAID sulindac.” It appeared online in March 2009, and has been cited six times, according to Thomson Scientific’s Web of Knowledge.

Here’s what we do know: Dental researchers at several universities in Egypt, including Cairo University, Future University, and Misr University published a paper together. According to the article, they gave dogs oral ulcers and then injected the ulcers with either fat-derived stem cells, bone marrow stem cells, or saline. The researchers conclude that the fat stem cells, also known as adipose derived stem cells, helped the dogs heal.
Unfortunately, we have no idea what went wrong, because the retraction notice is useless. Here in its entirety is the notice for “Adipose Stem Cells as Alternatives for Bone Marrow Mesenchymal Stem Cells in Oral Ulcer Healing”: Read the rest of this entry »
The International Association for Dental Research has retracted a student travel award after discovering that the recipient had previously published the work he used to secure the grant, including in an abstract he presented at the same conference last year.
The self-plagiarism was uncovered by an anonymous group of students at the Hong Kong University dentistry school, where the student is a PhD student. The unnamed students sent both the IADR and HKU faculty members a color-coded chart showing identical phrases between the 2014 abstract, a 2013 paper published in the Journal of Periodontal Research called “Human umbilical vein endothelial cells synergize osteo/odontogenic differentiation of periodontal ligament stem cells in 3D cell sheets,” and another abstract the authors presented at the 2013 IADR conference.
The paper and both abstracts were written by P.K.C.P. Panduwawala, who lost the travel grant, along with HKU’s former dean of dentistry L.P. Samaranayake; HKU’s associate dean for research L.J. Jin; and C.F. Zhang, part of HKU’s tissue engineering group.
The IADR’s page now lists the winners with a note at the bottom: Read the rest of this entry »
The Journal of International Oral Health has retracted a 2014 paper on dental pain by a group from India. Although the ostensible reason was plagiarism, we wonder if the offending authors might gone a bit further.
The article, “Sniffing out pain: An in vivo intranasal study of analgesic efficacy,” purported to be a study of 20 patients receiving different therapies for emergency oral pain. It has yet to be cited, according to Thomson Scientific’s Web of Knowledge. Here’s the abstract: Read the rest of this entry »
