Aim: Silver diamine fluoride (SDF) followed by potassium iodide (KI) application helps minimize discoloration; however, such an application may interfere with the bond strength of the restorative material. The aim was to assess the microtensile bond strength (mTBS) of SDF with KI-treated carious primary dentin, which were restored immediately or on the seventh day with glass ionomer cement (GIC) and/or composite resin. Materials and Methods: Thirty-six carious primary molars were collected, and gross debris was removed. Prior to the placement of the restoration, SDF/KI was applied to all the specimens and divided randomly into group I: immediate placement of restoration, and group II: seventh-day placement of restoration (n = 18, per group). Group I was further divided into group Ia: GIC was placed immediately, and group Ib: composite resin was placed. Group II was divided into group IIa: GIC placed on the seventh day, and group IIb: composite placed on the seventh day (n = 9, per group). The specimens were then stored in artificial saliva at 37°C. After 7 days, the specimens were sliced for microtensile strength test using a slow-speed diamond saw (Isomet 1000). The failure mode was evaluated with stereomicroscope at 40× magnification. Results: The mTBS was compared using Kruskal-Wallis test. Group Ib (immediate composite) showed the highest bond strength (1.71 ± 0.80) though this difference was not statistically significant (P = 0.88). The failure modes were compared using chi-square test, which showed no statistically significant difference between the groups. Conclusion: The mTBS showed no difference with the time of placement between the materials.
