What are four primary techniques of hemostasis used in surgery?

Four major physiologic events participate in the hemostatic process: vascular constriction, platelet plug formation, fibrin formation, and fibrinolysis.

What are hemostatic materials?

A series of hemostatic materials have been developed, e.g., thrombin and fibrinogen in polypeptide protein. Other macromolecular materials include natural materials (e.g., oxidized cellulose and chitosan) and polymeric materials (e.g., polyvinyl alcohol and polylactic acid).

What is hemostatic device?

Device Description: An absorbable hemostatic agent or dressing is a device intended to produce hemostasis by accelerating the clotting process of blood. It is absorbable.

Where does hemostasis occur?

Hemostasis is the natural process that stops blood loss when an injury occurs.It involves three steps: (1) vascular spasm ( vasoconstriction ); (2) platelet plug formation; and (3) coagulation. Vasoconstriction is a reflex in which blood vessels narrow to increase blood pressure.

What is surgical hemostasis?

Intraoperative control of bleeding during any surgical procedure is vital for achieving a positive patient outcome. Hemostasis can be achieved through practical and effective systemic or topical approaches.

What are the teeth divided into groups for dental hemostasis?

To avoid such an inconvenience, the teeth were divided into 3 groups. Hemostasis was attempted by using CaS in 11 teeth (group I), gauze tamponade in another 10 teeth (group II), or 20% ferric sulfate in the last 10 teeth (group III).

What is endodontic microsurgery?

Endodontic surgery has now evolved into endodontic microsurgery. By using state-of the-art equipment, instruments and materials that match biological concepts with clinical practice, it can be believed that microsurgical approaches produce predictable outcomes in the healing of lesions of endodontic origin. 1.

What is the triad of endodontic microsurgery?

The triad of endodontic microsurgery encompasses magnification, illumination, and instruments. Without any of these elements, microsurgery would not be possible. Illumination and magnification are provided by the surgical operation microscope and have fundamentally changed the way endodontic surgery is performed.

What are the limitations of Microsurgical endodontics?

The standard endodontic surgical instruments are too large for the microsurgical approach. Ultrasonic tips, condensers, pluggers, curettes, and mirrors were reduced in size to comfortably fit into an osteotomy no larger than 5 mm to gain access to the canals. [4] [
