What are the cells in inflammatory reaction of pulp?

Odontoblasts and dendritic cells cooperatively induce the pulpal responses by the expression of cytokines and prostaglandins and the sequential attraction of inflammatory cells, namely T cells, macrophages, neutrophils and B cells, and an increased CD4/CD8 ratio of T-lymphocytes [4,44].

What is inflammation of the dental pulp?

Pulpitis is inflammation of the dental pulp resulting from untreated caries, trauma, or multiple restorations. Its principal symptom is pain. Diagnosis is based on clinical findings, and results of x-rays and pulp vitality tests.

What cell type associated with immune response is present in severely inflamed pulp?

It is now well established that the normal dental pulp contains heterogeneous cell populations including a majority of fibroblast-like cells, but also inflammatory and immune cells (dendritic cells (DCs), histiocytes/macrophages, T-lymphocytes) (Figs.

What causes inflammation of tooth pulp?

According to a 2016 systematic review , the most common cause of pulpitis is when bacteria irritate the dental pulp through an area of tooth decay, including dental caries. Other causes of pulpal inflammation include: trauma or injury to a tooth. grinding or clenching the teeth.

What is chronic hyperplastic Pulpitis?

Chronic hyperplastic pulpitis (pulp polyps) usually occurs in molar teeth of children and young adults and is characterized by an overgrowth of granulomatous tissue into the carious cavity.

Which most important action of inflammation which causes pulp necrosis?

Following the spread of local inflammation, chemical mediators such as IL-8, IL-6 and IL-1 are released from necrotic tissues leading to further inflammation and odema, which advances to total necrosis of the pulp.

What is chronic pulpitis?

Pulpitis is usually chronic and progresses intermittently and unpredictably with or without acute phases. At some stage, the pulp is irretrievably damaged, probably because pressure from inflammation impedes pulpal blood flow. This causes loss of vitality.

What is the difference between acute and chronic pulpitis?

The difference between acute and chronic pulpitis is that with acute pulpitis the pain comes on all of a sudden and can be quite intense, whereas chronic pulpitis is characterised by duller but longer-lasting pain.

What is pulp in dentistry?

Dental pulp is the center part of a tooth comprised of connective tissue, blood vessels, and cells. If this gets infected it may become painful and need root canal therapy to salvage the tooth.

What are the Defence cells of the pulp?

Cells found in the dental pulp include fibroblasts (the principal cell), odontoblasts, defence cells like histiocytes, macrophages, granulocytes, mast cells, and plasma cells. The nerve plexus of Raschkow is located central to the cell-rich zone.

Is the pulp vital in chronic pulpitis?

In hyperplastic pulpitis, the tissue in the pulp chamber is frequently transformed into granulation tissue; however, radicular pulp tissue may remain normal/vital with vasodilatation [18]; undoubtedly, virtuous blood supply facilitates pulpal defense and healing.

What causes chronic hyperplastic pulpitis?

Hyperplastic pulpitis is a type of irreversible chronic pulpitis that occurs usually in young teeth where the pulp has been exposed by caries or trauma (1).
