Microbial Profiling in Pockets Related to Chronic Periodontitis Patients in UAE Population Using 16s RNA Metagenomics Sequencing

The study was developed in compliance with the Helsinki Declaration on medical research involving the Ethics Committee at Ajman University (2017-A-DN-04). Informed consent from all the participants was obtained before participation in the study. The participants were systemically healthy with no history of antibiotics for the past three months. Patients recruited for the study were diagnosed as Stage II Generalized periodontitis according to the classification from the 2017 world workshop on the "classification of periodontal and peri-implant disease and conditions". Periodontal status indicating the severity of interdental clinical attachment loss of 3-4mm, radiographic bone loss between 15%-33% and with no tooth loss were included. The complexity of periodontitis with a maximum probing depth of ≤ 5mm with horizontal bone loss and having an extent and distribution with >30% teeth involved were included in the study. A total of 80 plaque samples were collected with the clinical characteristics of the patient comprising of age between 25-39 years, 36 females and 44 males. The subgingival plaque was collected using a sterile curette from the buccal aspect of maxillary molars and lingual aspect of mandibular incisors, in a vial containing 200µl of Buffer CL.
