WITHDROWN: Effect of smoking habit on crestal bone height in maxillary sinus augmentation with bone grafts.

ABSTRACT

In relation to the article with reference "Carreño-Carreño J, Gómez-Moreno G, Aguilar-Salvatierra A, Menéndez-López-Mateos C, Piattelli A, Menéndez-Núñez M. Effect of smoking habit on crestal bone height in maxillary sinus augmentation with bone grafts. Med Oral Patol Oral Cir Bucal. (2018), doi10.4317/medoral.22439", published in Oral Medicine Oral Pathology and Oral Surgery in the modality "AHEAD OF PRINT - article in press", the authors mention that "The study was conducted according to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) Statement". However, and based on the opinion of several expert reviewers who have re-evaluated the article, it is considered that although "there has not been plagiarism", these STROBE criteria are not adequately met. In addition, the mentioned article is very similar to two articles that have already been published by the same authors in Clinical Oral Implants Research. The sample is the same; many data are repeated; and the only difference is the inclusion of a variable (smoking), which does not exert a significant effect. This outcome therefore would not justify publication of the paper in the journal. Retraction of the article is therefore decided.
