The pairing phase transition in some excited meadium nuclei are investigated by using extrapolating the experimental nuclear level densities (NLDs). Those data below the neutron binding energy $B_n$ are combined with the back-shifted Fermi-gas (BSFG) model for the energy above $B_n$ and up to about 120 MeV. The energy-dependent level density parameter in the BSFG format is suggested to be used to obtain the best fit to the NLDs. The S-shape observed in the heat capacities of both even and odd isotopes give a precise description of the pairing phase transition in these isotopes.
