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.
