The restoration of chiral symmetry at finite density and/or temperature is investigated in a wide class of one-gluon exchange models in the instantaneous approximation. If the effective quark interaction is less divergent than 1 k 2 for small momentum transfer k, we obtain Gaussian critical exponent...
