Yes. However this fully cured region is restricted to only the areas inside the voids which correspond to the instrument tip’s direct contact with the composite. This area has vertical walls and is retentive. It is completely surrounded by inhibited composite and becomes buried within the mass of the restoration and not against a margin.
