Purpose: The aim was to describe a comparative study of hemostasis obtained with the use of CaS versus gauze tamponade and versus ferric sulfate during endodontic surgical procedures.
N= 31 teeth
Inclusion and exclusion criteria:
1.Presence of PA lesion indicated for surgery.
2.Patients with severe systemic diseases , Acute inflammation, Surgical retreatment and Post operative complications.
Materials and methods:
•The sample was divided to three groups:
•Group I ( CaS 11 teeth ) , Group II ( gauze tamponade 10 teeth ) and Group III ( 20% ferric sulfate 10 teeth )
•Antibiotics were given to the patients 12 hours before surgery ( amoxicillin + clavulanic acid 1 gm twice daily )
•All periapical surgeries was done under the use of the OM.
•After root apices exposed , hemostasis was done using the three different materials.
•Root-end cavities were filled with MTA.
•Adequate hemostasis was defined as >> Root-end preparation dry, hemorrhage-free during procedure.
•Inadequate hemostasis was defined as >> Inability to keep the root end-preparation dry and hemorrhage-free.
Most highlighted results:
•Group I (CaS): Adequate hemostasis was achieved in all 11 cases.
•Group II (Gauzes): Adequate hemostasis was achieved in 3 of 10 cases . •Group III(Ferric sulfate): Adequate hemostasis was achieved in 6 of 10 cases.
Clinical significance: CaS is a successful material to control hemostasis which enhances optimal visibility and decreases the length of surgery
