The pairing phase transition in excited nuclei is systematically investigated by using the experimental nuclear level densities (NLDs) which have been compared with those obtained within the phenomenological back-shifted Fermi-gas (BSFG) model. The heat capacity is carried out by taking into account the experimental nuclear level density (NLD) data measured using the Oslo method for the low-excitation region below the neutron binding energy $B_n$ combining with the BSFG NLD model for the excitation energy from $B_n$ to about 120 MeV. The S-shape observed in the heat capacity of both even-even and even-odd isotopes gives a precise description of the pairing phase transition in nuclei. However, the S-shape exhibited is different not only between even-even and even-odd isotopes but also depends on the neutron number.
