- Abstract
Background: Dental caries is a localized, transmissible, infectious, and pathological process that leads to the destruction of the dental hard tissue. In ecological terms, this disease is caused by an imbalance in the oral ecosystem leading to the dominance of a flora, previously considered normal in the mouth and now treated as pathogenic. The main microorganisms associated to cariogenesis are, in order of frequency: (1) Streptococcus mutans (S. mutans) (mainly serotype c) and to a lesser extent S. sobrinus and S. gordonii; and (2) species of Lactobacillus and Actinomyces. Overall, the scientific community's consensus identifies S. mutans as the most important microorganism in dental caries. Therefore, isolation, identification, characterization, prevention and control strategies are directed primarily against S. mutans. Method: Based on our own research experience and contrasting it with that of other research groups this article describes the microbiology, isolation strategies, counting, and identification of S. mutans from dental plaque and saliva samples. It also depicts aspects of phenotyping, genotyping, phenotypic detection of bacteriocins and antimicrobial susceptibility of S. mutans strains. Conclusion: The correct understanding of the phenotypic and genotypic characteristics of S. mutans should lead to designing better prevention and control strategies.
