Extra channels in the root that may form due to developmental disruptions.

Inflammation of dental pulp, leading to pain and discomfort.

Visible areas in the pulp chamber that may indicate the presence of pulp stones.

Dental pulp provides nutrients, sensation, and supports tooth formation.

Problems that arise due to anatomical complexities such as accessory canals.

Bacteria entering the pulp via exposed accessory canals, causing infection.

Structure guiding root formation that can be disrupted, leading to anomalies.

Process by which diseases of the pulp develop, often involving inflammation.

The opening at the tip of a tooth root for nerves and blood vessels to enter the pulp.

Pulp is rich in nerves that detect stimuli and enable pain perception, aiding defense.

A network of nerves located in the coronal portion of the pulp, beneath the cell-free zone.

Nerves primarily from the trigeminal nerve that allow the sensation of pain in the tooth pulp.

Nerves from the superior cervical ganglion that regulate blood flow in the pulp's vascular vessels.

The pulp contributes to formation, circulation, and protection in a vital, healthy tooth.

With age, the pulp decreases in size due to secondary dentine deposition, affecting circulation and repair ability.

Small calcified areas found within pulp tissue, resembling dentine.

Dental pulp is made up of 75-80% water and 20-25% organic material, including cells and extracellular matrix.

Includes odontoblasts, fibroblasts, undifferentiated cells, defense cells, and contains blood and lymph vessels.

The pulp has four zones: odontoblast zone, cell-free zone, cell-rich zone, and pulp core.

Coronal pulp is in the pulp chamber; root pulp is in the root canals.

Dental pulp originates from ectomesenchyme of the dental papilla during development.

Health of dental pulp is crucial for tooth viability; damage leads to expensive treatments.

The space within the tooth that houses the pulp, surrounded by mineralized tissues.

Distinct cells lining the pulp's odontogenic zone, involved in dentinogenesis and sensory transduction.

Most prevalent cells in the pulp that form and maintain the extracellular matrix of collagen and ground substance.

Undifferentiated cells in the pulp that can become odontoblasts or fibroblasts.

Stem cells in the pulp with potential for differentiation into various cell types; under research for regenerative ability.

Cells like macrophages, T-lymphocytes, and some leukocytes found in the pulp core that function in immunosurveillance.

Matrix consisting of collagen fibers (type I and III) and ground substance that supports cells in the pulp.

Type I and III fibers in the extracellular matrix that increase in content with age.

Blood and lymph vessels providing circulation to the pulp, entering via the apical foramen.
