Dental caries, a progressive bacterial damage to teeth, is one of the most commondiseases that affects 95% of the population and is still a major cause of tooth loss.Recent years have seen an increase in research activity surrounding diagnostic methods, particularly in the assessment of early caries lesions. The use of technologies as adjunct to clinical visual examination for caries diagnosis will facilitate preventive care in dentistry to lower treatment cost as well as reduce the cost and time for testing potential anticaries agents. In recent years, the early diagnosis of dental caries has gained importance as conservative dentistry is kept in the forefront. Especially in pediatric patients, the dentist should focus on the early detection of dental caries and minimally invasive treatment options. The conventional caries detection methods often fail to detect initial enamel lesions that have not progressed to cavitation. For this reason, various new techniques have been developed aiding early detection of caries. The aim of this review is to give general information about recent caries detection methods and to mention their benefits when used in conjunction with conventional methods
