Claims14
A dental glass ionomer cement (GIC) composition comprising a zwitterionic material and a glass ionomer cement,
- wherein the zwitterionic material has a content of about 1 to 5 wt % based on the total mass of the dental glass ionomer cement composition,
- wherein the zwitterionic material comprises 2-methacryloyloxyethyl phosphorylcholine (MPC) and sulfobetaine methacrylate (SB), and
- wherein the MPC and SB are included in a weight ratio of 1:3 to 3:1.
A method of preparing a dental glass ionomer cement composition, comprising the steps of:
- mixing about 1 to 5 wt % of zwitterionic material in a liquid of glass ionomer cement (GIC) based on the total mass of the dental glass ionomer cement composition, and
- mixing the liquid of glass ionomer cement (GIC) in which the zwitterionic material is mixed, and a powder of glass ionomer cement (GIC),
- wherein the zwitterionic material comprises 2-methacryloyloxyethyl phosphorylcholine (MPC) and sulfobetaine methacrylate (SB), and
- wherein the MPC and SB are included in a weight ratio of 1:3 to 3:1.
