Mediators of Inflammation
|November 6, 2015
Summary
Inflammation, previously viewed negatively, is now understood as crucial for pulpal healing and dentin repair. It initiates a cascade of cellular events leading to the formation of a reparative dentinal bridge.
Area of Science:
- Endodontics
- Regenerative Medicine
- Dental Pulp Biology
Background:
- Historically, inflammation was considered detrimental to pulpal healing.
- Recent evidence highlights inflammation's essential role in initiating pulp repair processes.
Purpose of the Study:
- To re-evaluate the role of inflammation in pulpal healing.
- To elucidate the cellular and molecular mechanisms underlying reparative dentin formation.
Main Methods:
- Review of current evidence on inflammation and pulpal healing.
- Analysis of cellular responses to capping agents and their role in mineralization and dentin bridge formation.
Main Results:
- Inflammation, particularly mild inflammation induced by capping agents, is a prerequisite for pulpal regeneration.
- Pulp cells proliferate and differentiate into odontoblast-like cells, producing reparative dentin.
- Specific molecules and mediators orchestrate the formation of a dentinal bridge, closing pulp exposures.
Conclusions:
- Inflammation is a critical driver of pulpal healing and dentin repair.
- Understanding these inflammatory processes allows for targeted therapeutic strategies to enhance pulp regeneration.

18.9K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

01:19Overview of Regeneration and Repair
5.8K
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.

18.6K
The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

01:24Inflammatory Response II: Inflammatory Exudate and Tissue Repair
9.3K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...
