The influence of using a temperature-dependent pairing term on the back-shifted Fermi gas (BSFG) model of nuclear level density of some even-even nuclei has been investigated. We have chosen an approach to determine the adjustable parameters from theoretical calculations, directly. The exact Ginzburg-Landau (EGL) theory was used to determine the temperature-dependent pairing energy as back-shifted parameter of the BSFG model. The level density parameter of the BSFG model has been determined through the Thomas-Fermi approximation. The level densities of 96Mo, 106,112Cd, 106,108Pd, 164Dy, 232Th, 238U and heat capacities of 96Mo and 164Dy nuclei were calculated. Good agreement between theory and experiment was observed.
