Clinical effectiveness of mechanical-chemical tissue displacement methods.

The following conclusions were made after statistical analysis. There was no significant difference between racemic epinephrine cord and aluminum sulfate cord. Both racemic epinephrine cord and aluminum sulfate cord were more effective than nonmedicated cord. There was no difference between dry cord and water-saturated cord. Hemorrhage control with a cord saturated in Hemodent was more effective than water-saturated or dry cords. The racemic epinephrine cord was not superior to the aluminum sulfate cord, so the dentist could eliminate a cord with potential systemic effects and substitute the more innocuous cord. Hemodent approximately doubled the hemostasis success of any cord used in this study.
