MAY, PERIODONTITIS
We conducted a randomised clinical trial in the Department of Dental and Oral Pathology at the Lithuanian University of Health Sciences in Kaunas, Lithuania, from January to May 2019. Systemically healthy individuals with periodontitis were involved in the study. All included patients must have signed an informed consent form, were willing and able to attend follow-up appointments, and agreed to coded data collection. Patients were given enough time to analyse the protocol of the study and were free to exit the study at any time without a specific reason. After they signed the informed consent form, they were randomly assigned to the control or experimental group (allocation ratio 1:1).The study was performed according to CONSORT guidelines for randomised controlled clinical trials.
