Abstract: Groups with self-centralizing elements have been investigated in recent papers by Kappe, Konvisser and Seksenbaev. In particular, if $ G = A$wr$ B$ is a wreath product some necessary and some sufficient conditions have been given for the existence of self-centralizing elements and for $ G = \left\langle {{S_G}} \right\rangle $, where $ {S_G}$ is the set of self-centralizing elements. In this paper $ {S_G}$ and the set $ {R_G}$ of elements with trivial centralizer are determined both for restricted and unrestricted wreath products. Based on this the size of $ \left\langle {{S_G}} \right\rangle $ and $ \left\langle {{R_G}} \right\rangle $ is found in some cases, in particular if $ A$ and $ B$ are $ p$-groups or if $ B$ is not periodic.
