A real miniature scaffolding. Here is how the researchers define the system they have developed to improve the treatment of periodontitis, or “gum disease”, which affects 10% of the population. L’studypublished in the Open Dentistry Journal, presents a new biomaterial, the collagen hydrogel, combined with a growth factor, called FGF2.
Researchers at the Hokkaido University Graduate School of Dental Medicine in Japan applied this sponge-like device to dogs that had undergone surgery to treat their periodontitis. They carried out checks ten days after surgery, then 4 weeks later.
Gum tissue regenerates better
Result: the gel improves the results of periodontal surgery. It helps to regenerate the tissues on the surface of the root of the teeth, and promotes the attachment of the gums. The periodontal tissue (ligament, alveolar bone) rebuilds better, and resists chewing. The gel also accelerates healing and is completely biodegradable. In the longer term, it prevents the loss of teeth and could therefore represent a solid alternative to the process currently used. The latter consists of a polymer structure accompanied by an artificial bone graft.
