The effects of temperature on the setting of glass ionomer (polyalkenoate) cements.
Glass ionomer (polyalkenoate) cements have proved to be superior to zinc phosphate cements as orthodontic luting agents. Setting behaviours at different temperatures were recorded by an oscillating rheometer under controlled conditions. The working time of these cements can be increased by mixing on a chilled glass slab with setting time at mouth temperatures remaining rapid. Where more than one orthodontic band is cemented per mix, the authors recommend refrigeration of the glass slab for at least one hour prior to mixing the cement.
