The pulp–dentin is a highly vascular loose connective tissue surrounded by a component of calcified connective tissue, the dentin. Although there are very obvious structural differences between pulp and dentin, the following reasons suggest they be treated as an integrated complex.

• During tooth development dentin is formed by odontoblasts of the pulp. After tooth development, peritubular and secondary dentin continue to be formed by the pulp odontoblast.

• The sensitivity of dentin depends on the presence of odontoblasts.

• The capacity of dentin to respond to irritation such as tooth wear, or dental caries, depends on odontoblasts.

• Both sensitivity and response to irritation are directly affected by the state of the entire pulp tissue.

• From an operative point of view, any procedure involving dentin is a procedure involving the pulp; any material or medication placed against dentin is a material or medication placed against the pulp.
