Pulpal effect of the bacterial products Bacteria found in caries and plaque have the capacity to initiate PMN infiltration and abscess formation.
Mechanisms of pulp tissue damage Pulpal response to bacteria can result in chemotaxis of cell mediated and humoral immunological cells, complement activation, and vascular changes.
Healing capacity of the pulp The pulp has excellent healing capacity. Inflammatory response can vary from minor to severe, reparative dentin formation can slow the effect of caries, localized abscesses can heal
