In periodontitis, EVs play a pivotal role in regulating the biological functions of both periodontal tissue cells and immune cells, as well as the local microenvironment, thereby promoting periodontal injury repair and tissue regeneration. (biomedcentral.com)
By performing local transplants, other non-periodontal-derived MSCs such as dental pulp stem cells (DPSCs), bone marrow stem cells (BMSCs), and adipose tissue-derived stem cells (ADSCs) also aid in the regeneration of periodontal tissue [ 12 ]. (biomedcentral.com)
These results provide key insights into the mechanisms that underlie development of periodontal disease," said NIDCR director Martha J. Somerman, DDS, PhD. "Importantly, they also offer compelling evidence for therapeutic targeting of specific cells, which might eventually help us provide better treatment and more relief to patients with this common disease. (dentistrytoday.com)

The researchers reasoned that if Th17 cells are as important to periodontitis as the animal studies suggested, a lack of Th17 cells should protect against gum disease. (dentistrytoday.com)
Our clinical observations point to the relevance of our animal studies to humans and provide further evidence that Th17 cells are drivers of periodontitis," said NIDCR researcher and first author Nicolas Dutzan, PhD. (dentistrytoday.com)
