The aim of this in vitro study was to investigate the effect of silver diamine fluoride (SDF) on the microleakage of resin composite. Forty-five freshly extracted non-carious human mandibular third molar teeth were used in the study. Five of them were used as negative control. Two class V cavities (3x3x2mm) were prepared. The teeth were randomly assigned into two groups: Group 1: Dentin bonding (G-aenial bond,GC Corp., Tokyo, Japan) was applied and light-cured for 20 s. All cavities (n=40) were restored with resin composite (G-aenial posterior composite,GC Corp., Tokyo, Japan). Group 2: 38% SDF (Saforide, Toyo Seiyaku Kasei, Japan) was applied for three minutes, followed by a rinse for 30 seconds. Then the cavities (n=40) were restored as the same protocol in Group 1. The specimens then were submitted to 1000 thermocycles with 30 s baths at temperature of 5oC and 55oC and a dwell time of 10 s in a resting bath at 24oC. All samples were subsequently immersed in 0.5% basic fucsin solution for 24 hours. Marginal leakage was evaluated under stereomicroscope at x40 magnification. The significance between the groups was determined using Wilcoxon and Chisquare tests. No significant difference in microleakage scores was found betwen control and experimental groups. The findings of the present study revealed that using silver diamine fluoride did not effect the microleakage scores of resin composite. Further clinical studies with using potassium iodide to mask the staining effect of SDF must be needed. Experimental article (J Int Dent Med Res 2013; 6: (3), pp. 105-108)
