The Effect of Systemic Diseases on Periodontal Remodeling

The SD research area investigates how chronic systemic diseases affect the structure, function, and regenerative capacity of the periodontium.

The focus is on diseases of high societal relevance, including chronic kidney disease, cardiovascular disease, heart failure, metabolic disorders, liver disease, and hematological disorders. These diseases lead to the release of numerous circulating mediators that can influence inflammatory processes, mineralization, stem cell functions, vascular integrity, and tissue homeostasis.

The goal of this research area is to identify the molecular mechanisms through which systemic diseases alter periodontal remodeling. This is intended to lead to the discovery of new biomarkers and therapeutic targets for the prevention and treatment of periodontal tissue damage.

Projects SD-01 through SD-09 investigate different clinical conditions and their effects on the periodontium. Together, they form the basis for a comprehensive understanding of the systemic influence on oral health.

PR-Projects

Pathophysiology of Periodontal Remodeling

The PR Research area focuses on the fundamental biological mechanisms that govern periodontal remodeling.

The periodontium is a highly dynamic tissue whose stability depends on a complex interplay of mineralization, mechanical stress, inflammation regulation, microbial communities, and stem cell activity. Changes in these processes can lead to tissue degradation, alveolar bone loss, and ultimately tooth loss.

The projects in the PR research area investigate the cellular and molecular basis of these processes and analyze how they are influenced by systemic diseases. They employ modern approaches from biomaterials research, stem cell biology, tissue engineering, imaging, and experimental disease modeling.

Projects PR-01 through PR-05 address various aspects of the pathophysiology of periodontal remodeling—ranging from the regulation of cellular signaling pathways and tissue homeostasis to the interaction between the immune response and the microbiome, and extending to mechanisms of regeneration and tissue renewal. Together, they lay the scientific foundation for understanding the biological processes that determine the health and disease of the periodontium.

The findings are intended to contribute to the development of new strategies for promoting tissue regeneration and for the targeted treatment of disorders of periodontal remodeling.
