The Bottom Line:

Sarrett, DMD, MS ppreditor@ada.org Glass Ionomer Cements Between the two self-curing pure glass ionomers evaluated, GlassLute failed to meet minimum standards for strength and acid erosion. GC Fuji Cem, GC Fuji PLUS, and RelyX Luting Plus (all resin-modified glass ionomers) were highly rated products in the survey among clinicians. GC Fuji Cem had the most favorable film thickness of all cements tested when loaded immediately; however it was completely set when tested at the manufacturer’s stated working time. GC Fuji Plus (a RMGI) and PermaCem Dual Smartmix, a compomer more comparable to a resin cement, had the highest laboratory scores. GC Fuji Plus, a resin-modified glass ionomer, appears to be a good overall choice for a luting cement with glass ionomer advantages. It had among the highest laboratory scores and ratings among clinicians.
