| 1 | Influence of Aging and 2-hydroxyethyl-methacrylate Content on the Color Stability of Experimental 2-hydroxyethyl-methacrylate-added Dental Glass Ionomers显示文摘Color stability of dental resin modified glass ionomer (RMGI) has been a challenge to dentistry; therefore, systematic changes in 2-hydroxyethyl methacrylate (HEMA) content were performed experimentally to find an idea to enhance the color stability. Changes in color (△E*ab) and color coordinates (△L*, △a* and △b*) of experimental 10-50 wt pct HEMA-added dental glass ionomers (HAGIs) and corresponding RMGIs were determined after 5000 cycles of thermocycling. Color changes of HAGIs were not influenced by the HEMA content while △L*, △a* and △b* values were influenced by the HEMA content. Color stability of 30% or 40% HEMA-added HAGIs was not different from those of the commercial RMGIs. Since the influence of HEMA itself on the color stability of HAGIs was limited, compositional modification to increase the color stability of these materials should be developed. | Bin Yu Guangfeng Zhao Honam Lim Jinik Lira Yongkeun Lee | 2010 | Journal of Materials Science & Technology2010，26，4： | 0 |
