We employed the Skyrme-Hartree-Fock model to investigate the density distributions and their dependence on nuclear shapes and isospins in the superheavy mass region. Different Skyrme forces were used for the calculations with a special comparison to the experimental data in {sup 208}Pb. The ground-state deformations, nuclear radii, neutron-skin thicknesses and {alpha}-decay energies were also calculated. Density distributions were discussed with the calculations of single-particle wave functions and shell fillings. Calculations show that deformations have considerable effects on the density distributions, with a detailed discussion on the {sup 292}120 nucleus. Earlier predictions of remarkably low central density are not supported when deformation is allowed for.
