highly significantp = 0.001
In the conventional technique (group III) on the buccal side in both subgroups (RMGIC and resin cement), grade II or III microleakage was not reported in either group, which was highly significant at p = 0.001, followed by the Hall's with SDF using resin cement, and the highest amount of microleakage was shown by the Hall's technique alone using RMGIC cement.
