In semiconductor quantum dots, electrons behave as Fermi-Landau quasi-particles interacting through a week screened interaction. For confined systems a genuine "microscopic" derivation of how this screening takes place is made more complicated than in the bulk case because it has to be treated concurrently with the reorganization of charges generating the smooth electrostatic confining potential in which the electrons are evolving. This contribution gives a discussion of this problem in a
