These results show that in case of clinical reexamination without support means, such as fluorescent laser, it is extreme easy to leave carious lesions unchecked, especially lesions in levels D1 and D2 which are different slightly in vision checking of dried or wetted tooth surface (when applied examination and diagnosis criteria of ICDAS). Missing possibility is very high, almost 50%, when applying dental caries recognition criteria of WHO (1997) which treats only lesions causing cavities and tugging-back with explorer as dental caries.
