简要总结
This study aims to assess Pro-Resolution Mediator levels during non-surgical periodontal therapy in individuals with Stage III and IV periodontitis, comparing them to healthy subjects. Periodontitis, a chronic inflammatory condition affecting tooth-supporting tissues, can lead to tooth loss and systemic complications. Understanding the role of pro-resolving lipid mediators in inflammation resolution may offer insights into therapeutic benefits associated with these mediators.
详细描述
Periodontitis is a chronic inflammatory disease that affects the tooth-supporting tissues, it produces a slow destruction of the periodontium that may eventually result in tooth loss. Periodontitis is caused by a dysbiosis of the immune system where there is an imbalance between the processes that activate and terminate the inflammatory process.(Van Dyke, 2020) Pro-resolving lipid mediators (PMs) play a key role in actively resolving inflammation, modulating immune responses, and promoting tissue healing. However, the understanding of PMs in periodontitis and their role in the enduring nature of the disease has not been sufficiently studied in a clinical setting. It has been suggested that PM levels vary between periodontitis patients and healthy individual with periodontal therapy potentially restoring the balance between pro- and anti-inflammatory mediators. (Van Dyke, 2017) The study aims to provide insights into inflammation resolution mechanisms in periodontitis and the therapeutic potential of PMs.
This study aims to Assess Pro-Resolution Mediator Levels During Periodontal Therapy in Patients with Periodontitis Stage III and IV compared to healthy patients.
Hypothesis Null Hypothesis: pro-resolution mediators' level before and after non-surgical treatment in stage III and IV periodontitis compared to healthy patients, there will be no difference in level before and after non-surgical treatment between stage III and IV periodontitis compared to healthy patients.
Trial design:
The current study design is a before and after trial with a single (interventional) population measured before and after treatment compared to a negative control of healthy patients.
