The one-loop self-energy is evaluated for d{sub 3/2} and d{sub 5/2} states in hydrogenic ions, and good agreement found with previous calculations. Results are compared to what is known of the Z{alpha} expansion and higher-order binding corrections inferred for these states as well as for their fine structures. Screened Kohn-Sham potentials are then used to evaluate the one-loop self-energy corrections to n = 2 states of lithiumlike ions for Z = 10 - 100, n = 3 states of sodiumlike ions for Z = 20 - 100, and n = 4 states of copperlike ions for Z = 40 - 100. The importance of these screened calculations for the interpretation of recent high accuracy experiments is emphasized.
