The Immune System: Basis of so much Health and Disease: 2. Innate Immunity

Area of Science:

• Immunology
• Oral Biology

Background:

• The immune system is the body's defense against pathogens.
• Immune system disturbances lead to immunocompromised states, autoimmune diseases, and auto-inflammatory conditions.
• A healthy immune system is vital for maintaining the health of dental and oral tissues.

Purpose of the Study:

• To present the fundamental principles of the immune system.
• To focus on the innate immunity component of the immune system.
• To highlight the clinical relevance of immunological understanding for dental professionals.

Main Methods:

• This article provides a foundational overview of innate immunity.
• It discusses the role of the immune system in health and disease.
• The content is presented as part of a series on basic immunology.

Main Results:

• Innate immunity comprises the first line of defense against pathogens.
• Dysregulation of immune responses can result in disease.
• A functional immune system is essential for oral tissue homeostasis.

Conclusions:

• A basic understanding of the immune system, particularly innate immunity, is essential for modern dental clinicians.
• Knowledge of immunology aids in comprehending oral health and disease.
• This series aims to equip dental professionals with foundational immunological knowledge.
