Study Notes

Inflammation

Acute inflammation is a rapid response to injury, characterized by redness, heat, swelling, pain, and loss of function. It is typically short-lived.
Chronic inflammation is a long-standing inflammatory process lasting for weeks, months, or even years. It may become less obvious over time with subtle differences.
Chronic inflammation impacts dentistry both orally and systemically, contributing to conditions like periodontitis.

Chronic Inflammation

Chronic inflammation is a complex process involving a constant battle between destruction and healing.
While the body attempts to protect itself by generating processes like white blood cells, chemical mediators, barriers, and vasodilation, chronic inflammation can lead to tissue damage.
Chronic inflammation is often less obvious than acute inflammation and can go unnoticed for extended periods.
Key inflammatory cells in chronic inflammation are lymphocytes, which contribute to phagocytosis and secretion of inflammatory mediators.
Fibroblasts are also involved in chronic inflammation, creating collagen to help heal the wound, leading to a more fibrotic appearance.
Chronic inflammation occurs when the host defense cannot clear the initial insult (e.g., bacteria).

Granulomas and Chronic Inflammation

In an attempt to wall off the infection and prevent seepage, the body can form granulomas.
These granulomas are essentially walled-off areas of infection, which can grow and require an extended blood supply for survival (angiogenesis).

Comparing Acute and Chronic Inflammation

Acute inflammation typically involves pain, swelling, or discomfort, making it more noticeable.
Chronic inflammation, on the other hand, is often less obvious and can persist for long periods.

Wound Healing

Causes of Wounds

Surgical incisions, trauma, pressure, friction, and poor circulation can all cause wounds.

Risk Factors for Wound Development

Factors influencing tissue healing include:
- The wound's freedom from foreign bodies, pathogens, and the extent of damage.
- The body's response, considering individual health status and any pre-existing medical conditions that may hinder healing.
Risk factors for developing a wound include:
- Medical therapies such as steroids, chemotherapy, and radiation.
- Disease processes, acute or chronic.
- Hereditary conditions.
- Nutritional status.
- Stress levels.
- Age (young or old).

Types of Wounds

Intentional wounds result from procedures like surgery.
Unintentional wounds occur due to accidents or other unforeseen incidents.
Open wounds are visible and exposed.
Closed wounds are beneath the skin's surface.
Clean wounds are free from contamination.
Contaminated wounds have come into contact with foreign material or pathogens.
Infected wounds have been invaded by bacteria or other microorganisms.

Describing Wounds

Abrasions are scrapes that remove the top layer of skin.
Contusions are bruises caused by blunt force trauma.
Incisions are clean cuts made with a sharp instrument.
Lacerations are tears or jagged cuts with a sharp object.
Penetrating wounds pierce through the skin and underlying tissue.
Puncture wounds are deep, narrow wounds caused by objects with sharp points.

Stages of Wound Healing

Primary Healing (First Intention): Occurs when the wound edges are approximated (brought close together) and results in minimal scarring.
- Inflammation: The initial phase involves inflammation, blood clotting, and removal of debris.
- Proliferation: The second phase involves tissue regeneration and the formation of new blood vessels (angiogenesis).
- Maturation: The final stage involves the remodeling of scar tissue and the strengthening of the wound.
Secondary Healing (Second Intention): Occurs when wound edges are not approximated and results in more scarring.
Tertiary Healing (Third Intention): Occurs when a wound is intentionally left open for a period of time due to infection or when there is a need for drainage, before being closed later.
