Menstrual Cycle and Platelet-rich Fibrin

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical trial is to test effect of menstrual cycle (MC) on growth factors of platelet rich fibrin (PRF) in health condition. The main questions it aims to answer are: question 1: Does MC have an effect on growth factors in PRF? question 2: In which menstrual phase are growth factors higher? question 3:Does the change in the number of blood cells in the menstrual cycle have an effect on PRF? Participants will describe the main tasks participants will be asked to do.

Detailed Description
-----------------
Abstract Platelet-rich fibrin (PRF) is frequently used in periodontal regenerative treatments. Thanks to the growth factors in its content, it affects the healing positively. Studies have shown that the size and content of PRF are affected by variables such as age, gender, centrifugation speed and inflammation. It is known that during the menstrual cycle (MS) phases in women, changes occur in cell numbers and growth factors in the blood. The aim of this study is to determine the size of the PRF and the epidermal growth factor (EGF), insulin-like growth factor-1 (IGF-1), platelet-derived growth factor-BB (PDGF-BB), transforming growth factor-β1 (TGF-β1) and vascular endothelial growth factor (VEGF). PRF membrane will be formed from the blood of each individual in the study, taken on days 1-2 (M), 8-10 (PF), 12-14 (OD) and days 22-24 before menstruation (PmD). The size of the membranes will be measured. On the same days, individuals will have a complete blood count. The growth factors levels of each PRF membrane obtained at the 1st, 24th and 72nd hours will be determined. At the end of the study, the growth factors contents of the PRF membranes obtained in different phases of MS will be compared. In addition, the effect of the results of the complete blood count of the individuals on the PRF membrane will be evaluated.
