According to Schroder, (36) lack of hemostasis before applying CH affects treatment because clots may form a barrier that prevents contact between the material and the
exposed pulp; furthermore, clots may also act as a substrate for microorganisms, leading to pulp infection.
Whereas mechanically
exposed pulp heals efficiently, exposure by carious decreases the ratio of successful treatment (4).
Furthermore, the materials that possess both optimum flow ability and antibacterial properties might theoretically eliminate residual microorganisms located around
exposed pulp without damaging pulp tissue.
When dental pulp is exposed, direct pulp capping is often performed; in this process, a compound such as calcium hydroxide is placed directly over the
exposed pulp to preserve its vitality.
In direct pulp capping the
exposed pulp was dressed with a medicament or dental material, with the specific aim of maintaining pulpal vitality and health.
In a study on young posterior teeth, Mejare and Cvek [1993] suggested that deep carious exposures be opened up so that 1 to 3 mm of
exposed pulp can be removed and the pulp can be covered with CH.
