Grape Seed Proanthocyanidins: A Novel Source Of Dental Biomaterials And Unique Phytochemistry

Composite-based, tooth colored dental restorations, in spite of their aesthetic appeal, are limited by a short life span. Every subsequent restoration results in the loss of healthy dental tissue. Thus, a bio-mimetic approach has been developed to enhance the mechanical strength of dentin using plant-derived proanthocyanidins (PACs). From a panel of eight active plants, grape seed extract showed the highest dentin biomodification potential, a 15-fold enhancement of dentin stiffness measured in MPa.
