Neutrophile in Parodontaler Gesundheit Und Krankheit


Neutrophils are a type of white blood cell that play a crucial role in the immune response. They are the first line of defense against bacterial infections and are particularly important in maintaining periodontal health. This article will explore the role of neutrophils in periodontal health and disease.

Neutrophils and Periodontal Health

1. Neutrophil Function

Neutrophils are highly specialized cells that are capable of phagocytosis, the process of engulfing and destroying bacteria. They release antimicrobial substances and enzymes that help eliminate bacteria and prevent infection. In periodontal health, neutrophils play a crucial role in maintaining the balance between oral bacteria and the immune system.

2. Neutrophil Recruitment

When oral bacteria invade the periodontal tissues, neutrophils are recruited to the site of infection. This recruitment is mediated by various chemical signals released by the bacteria and the host immune system. Neutrophils migrate to the site of infection and release their antimicrobial substances to eliminate the bacteria.

Neutrophils and Periodontal Disease

1. Neutrophil Dysfunction

In some cases, neutrophils may not function properly, leading to an impaired immune response. This can result in an overgrowth of bacteria and the development of periodontal disease. Genetic factors, smoking, and certain systemic conditions can contribute to neutrophil dysfunction.

2. Neutrophil Extracellular Traps (NETs)

Neutrophils can also release neutrophil extracellular traps (NETs), which are web-like structures composed of DNA, histones, and antimicrobial proteins. While NETs are important in trapping and killing bacteria, excessive NET formation can contribute to tissue damage and inflammation in periodontal disease.

Frequently Asked Questions

Q: How can neutrophil function be improved?

A: Maintaining good oral hygiene, quitting smoking, and managing systemic conditions can help improve neutrophil function and reduce the risk of periodontal disease.

Q: Can neutrophil dysfunction be treated?

A: In some cases, neutrophil dysfunction can be managed with medications and therapies that target the underlying cause of the dysfunction. However, treatment options may vary depending on the specific condition.


Neutrophils play a crucial role in maintaining periodontal health by eliminating bacteria and preventing infection. However, dysfunction of neutrophils can contribute to the development of periodontal disease. Understanding the role of neutrophils in periodontal health and disease can help in the development of targeted therapies for the prevention and treatment of periodontal disease.
