Oral histology LO 7 part 3- pulp

Coronal

The ————— pulp occupies the crown. These are the pulp horns which protrude into the cusps.

Radicular

——————— pulp is the cervical region of pulp to the apex. Tapered or conical.

Apical foramen

The opening of the pulp to the periodontal ligament space.

Inductive

This is one of the functions of the pulp. The dental papilla interacts with oral epithelium to initiate tooth formation.

Formative

This is one of the functions of the pulp. Odontoblasts line the pulpal walls. Dentin dentin surrounds and protects the pulp.

Protective

This is one of the functions of the pulp. Response to stimuli can cause inflammation.

Nutritive

This is one of the functions of the pulp. Blood vessels supply oxygen and nutrition to the developing and functional tooth.

Reparative

This is one of the functions of the pulp. Response to stimuli can cause tertiary/——————— dentin formation.

Fibroblasts

Cells found in the dental pulp include fibroblasts, odontoblasts, defense cells like lymphocytes, granulocytes, mast cells, and plasma cells. Like all connective tissue, the ——————— are the largest group of cells in the pulp.

Odontoblasts

These are the 2nd largest group of cells in the pulp, but only their cell bodies are located in the pulp. The —————————— are located only along the other pulpal wall.

Odontoblastic layer

There are 3 layers of the pulp. The outer layer being the —————————— layer. The most cellular dense.

Cell free zone

This is the 2nd layer of the pulp. Nerve and capillary plexus.

Cell rich zone

This is the inner layer of the pulp. Increased density of cells, and extensive vascular system.

Accessory/lateral canals

This would be lateral to the apical foramel. 33%-50% of permanent teeth have ——————— canals. Inflammation of the pulp can spread to the PDL (and vice versa).

Pulp stones

These are quite common and may fill most of the pulp chamber. They are detected as radiopaque masses in radiographs and are only a problem during endodontic therapy.

Decreases

The size of the pulp ——————— with age.
