We study the chiral phase transition at finite temperature and chemical potential considering a non-local Polyakov chiral quark model with wave-function renormalization (WFR) in the propagator. In particular we analyze the role played by the Polyakov loop and compare results obtained with two different parametrizations and without the WFR
