The physical properties of this unique and extremely biocompatible restorative make it the ideal material for countless procedures that you will encounter in your practice. Geristore is a dual-cure cement. It's fluoride releasing, low coefficient of thermal expansion, and low polymerization shrinkage. A clinical evaluation of Geristore as a restorative material for root caries and cervical erosions showed it to be an acceptable material with 100% Alpha rating for retention, surface texture, and post-operative sensitivity. The auto-mix delivery system, with intra-oral tips, makes dispensing and placement fast and easy.
