In the framework of a holographic QCD approach we study the influence of matter on the deconfinement temperature T{sub c}. We first consider the quark flavor number (N{sub f}) dependence of T{sub c}. We observe that T{sub c} decreases with N{sub f}, which is consistent with a lattice QCD result. We also delve into how the quark number density {rho}{sub q} affects the value of T{sub c}. We find that T{sub c} drops with increasing {rho}{sub q}. In both cases, we confirm that the contributions from quarks are suppressed by 1/N{sub c}, as it should be, compared to the ones from a gravitational action (pure Yang-Mills theory)
