Abstract
A hemostatic composition for controlling oral bleeding or providing gingival tissue fluid control, which includes a hemostatic agent, a chemical agent for reducing the acidic activity of the hemostatic agent, and an aqueous base. The hemostatic compositions are useful in treating wounds in soft tissues in general. The hemostatic composition can be used to stop bleeding or control gingival tissue fluid flow without opening up the dentinal tubules in the dentin of a tooth that has been cut during dental restorative and reconstructive procedures. The hemostatic composition is also less aggressive and more gentle when used to treat wounds in soft tissues in general. The chemical agent is preferably an inorganic filler or high molecular weight polyol that reduces the acidic or other chemical activity of the hemostatic agent. This allows the smear layer plugs in the dentinal tubules to remain substantially intact to occlude passage of potentially harmful contaminants into the tubules and hence into the dental pulp. It also reduces inflammation and other irritating affects in soft tissue when using the hemostatic composition.
