Glass ionomer cement (GIC) has been widely used in clinical dentistry, because of its excellent features such as biocompatibility and low toxicity. However, the major disadvantages of current glass ionomer cement are short storage period and long curing time. In this study, a well-defined poly(acrylic acid-co-itaconic acid) (PAI) is prepared with controlled molecular weight. The resulting PAI copolymers are investigated by using proton nuclear magnetic resonance spectroscopy, infrared spectroscopy and gel permeation chromatography. The PAI copolymers were further used as an acid part for GIC. The outstanding storage stability was achieved by using PAI copolymers. The curing time was also controlled by controlling the formulation of acid part in GIC. |
