Hemostasis is a critical component in periodontal surgical procedures. Efficient control of bleeding is not only essential for optimal visualization and surgical precision but also vital for minimizing postoperative complications and promoting effective wound healing. This review discusses the fundamental principles of intraoperative and postoperative hemostasis, explores traditional methods and hemostatic agents, and provides an updated perspective on cutting-edge techniques, such as autologous platelet concentrates, chitosan-based agents, nanotechnology-integrated materials, and tranexamic acid applications. Emphasis is placed on both local and systemic factors influencing bleeding and the importance of individualized surgical planning.
