ABSTRACT:
An additive for glass ionomer cement comprising an effective amount of zircon to whiten, decrease the thickness and/or increase the setting time of the glass ionomer cement. The addition of zircon crystals to either the powder component of the liquid component of a glass ionomer cement allows one to control the color, mixability and handling characteristics, and setting time of the cement without adversely effecting the cement's intended functionality, such as the bond strength of the cement. The zircon additive may be utilized in conjunction with other additives and may be used in glass ionomer cements used as restorative materials, a prosthetic device cement, or as a luting agent, base or liner.
