We prove, using direct variational arguments, an explicit energy-treshold criterion for regular points of 2-dimensional Mumford-Shah energy (quasi-)minimizers. From this we infer an explicit constant for the density lower bound of De Giorgi, Carriero and Leaci.

Keywords: Local minimizer, Mumford-Shah energy, Density lower bound
