Evaluation of GCF And Salivary Ferritin, ALP And MMP-8 Levels of Individuals With Different Periodontal Diseases

The patient was asked to sit upright and tilt his/her head forward to collect saliva samples. İn this way, unstimulated saliva was allowed to accumulate in the floor of the mouth. The accumulated saliva was collected in a sterile container. It was then transferred to a propylene tube. The tubes were centrifuged and the clear part at the top of the tube was taken with a sterile syringe and transferred to a different propylene tube with 0.5 ml in each tube. Also, 4 samples of gingival crevicular fluid, 1 from each quadrant of the patient's jaw, were collected by means of paper strips and put into propylene tube. Tubes were stored at -80ºC until the day of analysis.
