Histophysiology of the dental pulp The dental pulp is one kind of loose connective tissue,and the respond to changes in environment should be the same as any other loose connective tissue.However, several factors make it unique and thus alter its ability to respond to irritation

Enamel 1.The pulp is almost Dentin totally Crown surrounded by a Pulp hard tissue (dentin),which Cementum limits the area for expansion and Root Canal Root restricts the pulp's ability to tolerate edema. Apex Copyright Symbyos 2008

1.The pulp is almost totally surrounded by a hard tissue (dentin), which limits the area for expansion and restricts the pulp's ability to tolerate edema

2.The pulp has almost a total lack of collateral circulation,which severly limits its ability to cope with bacteria, necrotic tissue, and inflammation
