“…GICs are widely used restorative materials in dentistry especially in pediatric dentistry. GIC has some advantageous properties, it has similar thermal expansion coefficient to that of dentin [1] , chemical adhesive properties [2] , and fluoride release property [3] . In spite of the advantageous properties of GIC, it has some drawbacks.…”

Background: Glass ionomer cements (GICs) is one of the materials of choice for restoring carious teeth in children due to its good qualities. Some modifications were made on GIC to improve its properties such as calcium chloride (CaCl 2 ) solution application. Objective: The purpose of this study was to evaluate the effect of 42.7 weight percent (wt%) CaCl 2 solution on two GIC restorations in relevance to color stability and surface hardness. Methods: Forty GIC specimens were prepared for each of the two tests and grouped according to the type of GIC into Fuji II light cure (Fuji II) group (n=20) and Fuji IX group (n=20). Each group was further subdivided into two subgroups: control (n=10) and experimental (n=10). Control specimens were left to set without treatment for five minutes. Experimental specimens were left to set for five minutes and then each specimen was immersed in ten milliliters (ml) of 42.7 wt% CaCl 2 solution for 60 seconds. Results: Fuji II group showed significant change in color after seven days while Fuji IX group showed no change in color at different time intervals. For surface hardness test, Fuji IX showed increase in surface hardness while Fuji II showed no change in surface hardness. Conclusion: Treatment of GIC with CaCl 2 solution does not affect the color stability of Fuji IX GIC but it might affect that of Fuji II GIC. CaCl 2 application on GIC improved the surface hardness of Fuji IX GIC however surface hardness of Fuji II had not changed.

“…The process II is more gradual and results in a diffusion of fluoride through the cement. 25,26,4,27 In the present study, the release of F IX, IZ and F II (GICs and RM-GIC) was probably due to an initial "burst" of fluoride release from the glass particles, which occurred when the fluoridecontaining glass powder reacted with polyalkanoic acid, so the enamel surface hardness averages were higher in comparison to B II and Z250.…”

“…31,10 Therefore, the inhibition of secondary caries associated with fluoride-releasing materials is attributed to a maintenance release of fluoride ions around restoration margins. 32,27,9 Among the conditions of this study, the EDS analysis did have proved to be a sensitive and effective method to detect minor alterations of Ca/P/F mineral content as likewise occurred in the surface hardness evaluation.…”

“…However, this potential is affected by several variables: the presence of fluoride compounds and their interaction with polyalkanoic acids, as well as the type and amount of resin used for the polymerization reaction. 28,29,27 Among fluoride releasing materials, the distance of 150 µm from the F II (RM-GIC) showed the greatest hardness, but there was no statistical difference between GICs.…”

“…This result was in agreement with previous findings. 33,27 In contrast, B II suffered a significant loss for calcium and a significant increase of fluoride in the enamel adjacent to the restoration. For Z250 and C (no treatment) there was no significant change in calcium, phosphorus and fluoride after pH cycling.…”
