How to mirror in sculpt mode? I was working on a character legs with symetry enabled, as one leg was getting in the way I decided to hide it. But now that I unhided it, all the details are not in this leg.

My question is how to mirror what I have in one leg to the other one, just as I can do using dyntopo?
Switch to Edit Mode, A x 1 (or x 2) to select all elements;
Press Spacebar, search for Symmetrize;
Tweak Direction and Threshold in F6 panel.




NOTE: A partial selection will simply duplicate / mirror the selection. In your case, you just need a correction, so you should select all elements first.
