1. An apparatus for use in applying a hemostatic agent to bleeding gingival tissue during dental procedures, comprising:

  • reservoir means for holding a quantity of hemostatic agent;

    means for applying the hemostatic agent at a desired location of the gingival tissue, the proximal end of the applying means being in communication with the reservoir means such that the hemostatic agent is applied under hydraulic pressure to the desired location by the distal end of the applying means;

    porous means secured to the applying means such that a portion of the porous means extend sufficiently beyond the distal end so as to provide for at least partial sealing of the distal end of the applying means when pressed against the gingival tissue, thereby causing the hemostatic agent to be forced into said tissue by the hydraulic pressure of the applying means, and the porous means further protecting the gingival tissue from damage by the applying means as the tissue is mechanically burnished during application of the hemostatic agent; and

    means for controlled dispensing of the hemostatic agent under hydraulic pressure from the reservoir means to the distal end of the applying means.
