What’s the pulp ?
The dental pulp is a tissue of mesenchymal origin that occupies the internal space of the tooth. It receives its nutrients via the apical foramen, or apex, and has two functions: construction, i.e. it is able to form dentin throughout its life; and defensive, by initiating painful responses to aggressions to the tooth. The high degree of sensitivity of the teeth is due to the abundant irrigation and innervation of the pulp. The odontoblasts, or dentin-generating cells, are found in its most superficial region. The fact that it is surrounded by hard tissues gives the pulp certain special characteristics and, after suffering an aggression, the edema that develops can easily give rise to cell necrosis (1)(2)(4).
