Ethics approval and consent to participate
: The procedure was in accordance with the approved guidelines and regulations of the local ethics committee of the University of Bern (Kantonale Ethikkommission: KEK). Human PDL fibroblasts were collected from periodontally healthy patients during regular orthodontic treatment unrelated to the study and thereafter irreversibly anonymized. Patients signed an informed consent for using the biological material for research purposes. For this procedure (consent of patient, using irreversible anonymized biological material obtained as “waste” during regular clinical therapy) no special previous ethical approval from the KEK was necessary.
