Abstract:
Background: Secondary caries is a caries lesion that starts at the margin of the restoration, it is influenced by the salivary flow rate. Conventional GIC materials are easily soluble in salivary flow so thar Water Settable GIC is a solution for dentist in terms of practicality and strength as the latest restorative material. Objectives: To analyze the effect of lactic acid and artificial saliva on the releasw of fluoride ion Water Settable GIC. Methods: Forty-eight specimens (diameter 5 mm x thickness 2 mm; n = 8 / group) were made with Water Settable GIC. Samples that met the criteria were divided into 6 groups. Samples were immersed for 1 and 7 days in an incubator in 37oC temperature. For control group aquadest used to immerse the samples. The levels of fluoride ion release were read using a UV-VIS spectrophotometer. The data obtained were tested using the SPSS application. Results: The One-Way Anova parametric test results of day one and seven (p<0,05). The Bonferonni Post Hoc test showed that there was a significant difference between all treatment groups lacticacid day 1 (10,505 ± 0,285), lactic acid day 7 (11,609 ± 0,202), artificial saliva day 1 (4,639 ± 0,227), artificial saliva day 7 (8,273 ± 0,184), aquadest day 1 (3,286 ± 0,475), aquades day 7 (5,778 ± 0,823). Conclusion: There is an effect of lactic acid and artificial saliva on fluoride ion from Water Settable GIC.
