The effect of certain materials as haemostatic agents in periapical surgery

Four different materials were used to assess their activities to control blood oozing. A surprising result showed that chlorhexidine(2%) has good haemostatic activity beside gel foam. Local anesthesia showed haemostatic activity for short time, while no effect of normal saline on blood oozing during operation. Further studies on this approach are recommended for further evaluation of haemostatic activity of chlorhexidine.
