RETRACTED: Dental unit waterlines: source of contamination and cross-infection

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Editor-in-Chief as the authors have plagiarized parts of papers that had already appeared in J. Dent., 35 (2007) 701–711, doi:10.1016/j.jdent.2007.05.003 and J. Dent., 35 (2007) 712–720, doi:10.1016/j.jdent.2007.06.002. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
