Periodontology Lab
Machine-translated · View original
A periodontology lab that studies the regeneration of lost periodontal tissue and the links between periodontal disease and the rest of the body.

AboutAbout the lab
Getting lost periodontal tissue back.
The Periodontology Lab conducts a broad range of research on periodontal disease, from basic to clinical studies.
The lab works on regenerating lost periodontal tissue using growth factors and scaffolds, which are materials that serve as a foothold for cells.
It also investigates the mechanisms linking the mouth and the whole body, such as how periodontal disease affects digestive and respiratory diseases.
The lab values the independence of graduate students and supports them in taking on new research that goes beyond the lab's existing themes.
Key terms
- Periodontal tissue
- The tissues around a tooth that support it, including the gums, the periodontal ligament, and the supporting bone
- Growth factor
- A protein that promotes the growth of cells or their differentiation into specific cell types
- Scaffold
- A material that serves as a foothold where cells can settle and multiply when tissue is being regenerated

ResearchResearch themes
The lab conducts a broad range of research on periodontal disease, from basic to clinical studies. Its two main pillars are the regeneration of lost periodontal tissue and the mechanisms by which periodontal disease affects the whole body.
*Illustrative imageRegeneration of Lost Periodontal Tissue
The lab evaluates the regenerative capacity of new scaffolds that incorporate growth factors such as bFGF and BMP, using cell experiments and bone defect models in rats and dogs. It also investigates a regeneration method that uses very weak high-frequency current in animal experiments.
*Illustrative imagePeriodontal Disease and Systemic Disease
Using periodontitis model mice and other models, the lab seeks to clarify how periodontal disease affects digestive and respiratory diseases, and the molecular mechanisms involved.
*Illustrative imageGingival Barrier and Control of Inflammation
The lab focuses on how gingival epithelial cells, which make up periodontal tissue, regulate barrier function, and on how immune cells suppress inflammation. It aims to apply this knowledge to the prevention and treatment of periodontal disease.
