Microbiome and Proteome Mapping in Periodontitis

Clinical periodontal measurements included PD, CAL, BOP (+/-), GI, and PI. Clinical recordings were performed at six points (mesiobuccal, buccal, distobuccal, mesiopalatal, palatal, and distopalatal) of all teeth, except the 3rd molars.

The whole unstimulated saliva samples were collected. Each participant was asked first to rinse the mouth completely with tap water for 2 minutes, wait for 10 minutes. Then the participants were requested to let the saliva pool in their floor of the mouth and to allow the saliva to drain passively into a falcon tube, 5 minutes.

5 ml of venous blood were taken from the antecubital vein by a standard venipuncture method.

GCF was collected from the six sites (mesiobuccal, buccal, distobuccal, mesiopalatal, palatal, and distopalatal) per tooth, except the 3rd molars, via steril paper strips.

Subgingival plaque was collected by inserting two standardized paper points (no:30) at six sites (mesiobuccal, buccal, distobuccal, mesiopalatal, palatal, and distopalatal) per tooth, except the 3rd molars.
