Dentine Caries Lesion represents the latest sign of the Dental Caries Disease. In order to discover and characterize the complexity and diversity of caries dentine microbiota have been made microbiological studies from 1890 to the present time. In this review, recent studies based on molecular techniques (PCR) that have allowed detect microorganisms which have not been identified in previous studies based on biochemical techniques of identification and selective cultures, are mentioned. Among microbial species detected in caries dentine can mention as much Gram-positive bacteria: Lactobacillus, Streptococcus, Propionibacterium, Bifidobacterium, Actinomyces, Eubacterium, Rothia, Arachnia, Micromonasy Pseudoramibacterium; as Gram-negative bacteria: Prevotella, Porphyromona y Selenomonas. It is important to continue the studies in this field in order to understand the microbial mechanisms responsible for the invasion and destruction of the dentine structure.
