Abstract
Aim: To the SBS of RMGI restoration to demineralized dentin in primary molars treated with SDF if the restoration was applied immediately or delayed and to evaluate the microhardness of artificially demineralized primary dentin without SDF application and before and after treatment with SDF in the three tested groups.
Materials and methods: The teeth were divided randomly into three groups (20 teeth each). Group 1; RMGI without SDF, Group 2; RMGI placed, and light cured immediately after SDF application and Group 3; RMGI placed and light cured two weeks after SDF application. All teeth were cut to expose at least 5X5 mm of sound dentin, which is then artificially demineralized and treated according to the assigned groups. SBS were tested and recorded. Microhardness of all specimens were measured at three stages: before and after demineralization, and after the separation of RMGI. 
Results: The comparison of SBS between all groups using a one-way ANOVA test was not statistically significant. Regarding hardness tests after treatment, there was a statistically significant difference between the group 2-SDF application with immediate restoration placement and light curing and both group 1 the ART group and group 3-the SDF with delayed restoration placement after 2 weeks. The immediate application of glass ionomer after SDF has the highest micro-hardness.
Conclusion: The restoration placement time had no effect on SBS if the restoration was placed immediately or delayed and the highest microhardness value was found in demineralized dentin pretreated with SDF application with immediate placement of the RMGI restoration.
