Abstract
A method for setting a dental glass ionomer cement by means of irradiation with a light to accelerateinitial setting, the cement comprising a fluoroaluminosilicate glass powder, a polycarboxylic acid and water, is disclosed. Further, the light to be irradiated in the method for setting the dental glass ionomer cement is preferably a light having a wavelength in the range of from 320 to 3,000 nm, and the irradiation intensity and irradiation time of the light are preferably from 200 to 3,000 mW/cm,and from 1 to 180 seconds, respectively. According to the method for setting the dental glass ionomer cement of this invention, the time for sensitization to water and the initial setting time can be shortened, without necessity of particularly performing an operation for preventing the sensitization to water with a varnish or the like.
