  We study confinement and chiral symmetry breaking phase transitions for QCD
and supersymmetric QCD. The method is based on some justified assumption
regarding the behavior of the Green function relevant for the potential between
two charges or a gap equation. We determine the number of flavors at which the
transitions to confinement and chiral symmetry breaking take place. We find
that whereas for chiral symmetry breaking the results are in perfect agreement
with those in the literature for confinement the situation is more complex.
