We review the two-zero mass matrix textures approach for Dirac neutrinos with the most recent global fit in the oscillation parameters.We found that three of the 15 possible textures are compatible with current experimental data,while the remaining two-zero textures were ruled out.Two textures are consistent with the normal hierarchy of neutrino masses and are CP-conserving,while the other is compatible with both mass orderings and allows for CP viol-ation.We also present the correlations between the oscillation parameters for the allowed two-zero textures.
