The dental pulp is the part in the center of a tooth made up of living soft tissue and cells called odontoblasts.

Contents

Anatomy

Each person can have a total of up to 52 pulp organs, 32 in the permanent and 20 in the primary teeth. The total volumes of all the permanent teeth organs is 0.38cc and the mean volume of a single adult human pulp is 0.02cc. Maxillary central incisor has shovel shaped coronal pulp with three short horns on the coronal roof and triangular in cross section. Cuspid has the longest pulp with elliptical cross section.

Crowns of the teeth contain coronal pulp. The coronal pulp has six surfaces: the occlusal, the mesial, the distal, the buccal, the lingual and the floor. Because of continuous deposition of dentin, the pulp becomes smaller with age. This is not uniform throughout the coronal pulp but progresses faster on the floor than on the roof or side walls.

Radicular pulp is that pulp extending from the cervical region of the crown to the root apex. They are not always straight but vary in shape, size and number. The radicular portion is continuous with the periapical tissues through the apical foramen or foramina.

Apical foramen is the opening of the radicular pulp into the periapical connective tissue. The average size is 0.3 to 0.4 mm in diameter. There can be two or more foramina separated by a portion of dentin and cementum or by cementum only. Most infections spread through the apical foramen from the pulp to periapical tissue.

Accessory canals are pathways from the radicular pulp, extending laterally through the dentin to the periodontal tissue seen especially in the apical third of the root.

Structural features

Pulp tissue removed during endodontic therapy by a size 20 broach file.

The central region of the coronal and radicular pulp contains large nerve trunks and blood vessels.

This area is lined peripherally by a specialized odontogenic area which has three layers (from innermost to outermost)

1. Cell rich zone; innermost pulp layer which contains fibroblasts and undifferentiated mesenchymal cells
2. Cell free zone (zone of Weil) which is rich in both capillaries and nerve networks. The nerve plexus of Rashkow is located in here
3. Odontoblastic layer; outermost layer which contains odontoblasts and lies next to the predentin and mature dentin

Cells found in the dental pulp include fibroblasts (the principal cell), odontoblasts, defence cells like histiocytes, macrophages (macrophage), granulocytes, mast cells and plasma cells

Clinical significance

An inflammation of a pulp is known as pulpitis. Pulpitis can be extremely painful and in serious cases calls for root canal therapy.

Functions

The primary function of the dental pulp is to form dentin (by the odontoblasts)

Other functions include

  • Nutritive: the pulp keeps the organic components of the surrounding mineralized tissue supplied with moisture and nutrients;
  • Sensory: extremes in temperature, pressure, or trauma to the dentin or pulp are perceived as pain;
  • Protective: the formation of reparative or secondary dentin (by the odontoblasts).
