In our research, however, due to the examination by new criteria to detect incipient carious lesions, DT, including D1T, D2T, and D3T, and DS, including D1S, D2S, and D3S, in which D1T, D2T, and D1S, D2S can be remineralized and reversible without filling application. Thus, if D1T, D2T and D1S, D2S decrease, DMFT and MDFS decrease, also.
