The study was conducted, recorded and reported in accordance with the Helsinki Declaration of 1975, as revised in 2000 and 2008 and prior to the commencement, the ethics committee of the Clinical San Carlos Hospital, Madrid, Spain, approved the protocol and informed consent forms under the registration number 13/404-P. This study was conducted in the ETEP (Etiology and Therapy of Periodontal Diseases) Research Group at the University Complutense of Madrid (Spain) from 11 of December 2013 to 12 of September 2016. All the investigators were trained on ISO-GCP standard before study start and on all study procedures during the site initiation visit by the sponsor. A clinical monitor of the sponsor in accordance with ISO 14155:2011 monitored this study. This study was performed in accordance with national regulations on ordinary care trials with CE marked medical devices within their intended use as well as with national regulations on data protection: Circular No. 07/2004, Decree 414/1996, DPA 15/1999, Royal Decree 1720/2007.
