Summary
Objective: To evaluate whether TiF4 solution and APF gel had any adverse effects on the surface morphology of newly developed glass ionomers. Study Design: Fifteen disc-shaped specimens of Fuji IX Extra, Fuji II LC and Ketac N100 were prepared and stored in 2 ml of artificial saliva at 37 degrees C for 8 weeks. Specimens of each material were divided randomly into three subgroups as 1 and 4 minutes application of 1.23% APF gel and 1 minute application of 1% TiF4 solution. Specimens were reaged for another 8 weeks. Microhardness, surface roughness values and surface morphology were evaluated by using Vicker's' hardness test, surface profilometty and scanning electron microscopy (SEM) for all time interventions, respectively.
