Nowadays, dental interventions provide maximum of hard tooth structure with help from minimal invasive preparations. Better understanding of caries as dynamic process between demineralization and re-mineralization of hard tooth structure leads to changes in repair techniques of teeth. Wide range of modern materials and composite materials of different viscosity enable successful closing and reconstruction of micro cavities, thus significantly decreasing risk of filling failure in cases when using classic extensive teeth preparation. Future is more oriented towards preventive approach enabling new technologies application in diagnostics, prevention and treatment.. So, minimal invasive dentistry is a part of preventive-reconstruction dentistry including prevention, re-mineralization and minimal intervention in preparation of soft dental tissues. Aim of this kind of therapy is prevention of natural tooth structure and postponing radical intervention as long as possible with accent to caries risk assessment, prevention and early diagnostics.
