Study Notes

Dental Pulp Structure and Function

The primary function of the ground substance in the dental pulp is to provide support and facilitate the exchange of nutrients and waste products between the pulp cells and the blood vessels.
The main component of the ground substance in the dental pulp is water.

Blood Supply and Lymphatic System

The primary function of the lymphatic system in the dental pulp is to remove excess fluids and waste products.
The posterior superior alveolar artery supplies blood to both the maxillary and mandibular teeth.

Inflammation and Immune Response

The consequence of the dental pulp being enclosed within a rigid chamber during inflammation is increased pressure and potential pulp necrosis.
The primary immune cells found in the dental pulp are macrophages and T-lymphocytes.

Cellular Components

The cell-rich zone of the dental pulp contains predominantly fibroblasts, mesenchymal stem cells, and white blood cells.
The odontoblastic layer at the periphery of the pulp is formed by odontoblasts.
The cell-free zone of the dental pulp is immediately subjacent to the odontoblast layer and contains capillary plexuses and nerve fiber ramifications.
The principal cellular component of the pulp core in dental pulp tissue is fibroblasts.
Stem cells are NOT visible under traditional histological staining in the dental pulp tissue.

Odontoblasts and Matrix

Odontoblastic processes extend into the predentin matrix at the periphery of the dental pulp.
Fibroblasts are responsible for the formation and maintenance of the fibrous component and ground substance of the connective tissue in the dental pulp.

Statements about Dental Pulp

Odontoblasts are responsible for the formation and maintenance of dentin.
Blood vessels in the dental pulp are primarily found in the cell-free zone.
The extracellular components in the dental pulp include the ground substance and the fibrous component.
The ground substance in the dental pulp is not directly involved in the formation of dentin.
