New research from Chicago College of Dentistry at the University of Illinois has uncovered that grape seed extracts could serve as invaluable strengtheners to dentine. Published in the Journal of Dental Research, the expedition details how the aforementioned constituent has the capability of enhancing composite resin fillings allowing them to last longer. Project author Ana Bedran-Russo mentions that the extracts can increase the durability of dentine, which is made up of calcified extracellular tissue and forms the layer beneath the external enamel.
Dentine comprises of mostly a collagen makeup, the most prevalent structural protein in skin and other connective tissues. Ana points out that resins have to affix themselves on the dentine, but the boundary between the two is unstable, and therefore restorations involving this area normally disintegrate. When fillings fail, dental carries come about, and the seal is lost.
The study seeks to reinforce the interface to in turn yield a strong bond between the resin and the dentine, particularly via the use of new natural materials.
The study group have conducted experiments and discovered that damaged collagen can restore itself with the help of flora based flavonoids found in most foods and vegetables, and extracts from grape seeds.
