ORAL MICROBIOTA: CHARACTERISTICS, RELATED PATHOLOGIES AND FUTURE PROSPECTS

The oral microbiota is represented by the set of bacteria and microrganisms that reside in the oral cavity. It is formed from bird and stabilizes during the period of permanent dentition. The oral microbiota poresents from 500 to 700 bacterial species, belonging to six main phyla, Firmicutes, Bacteroidetes, Proteobacteria, Actinobacteria, Spirochaetes and Fusobacteria. These bacteria partecipate in the formation of dental plaque, a sort of biofilm that deposits on the rigid surfaces of the oral cavity, and contributes to the healthy maintenance of the oral cavity. An alteration of the oral microbiota contributes to the pathogenesis of periodontitis, caries, gingivitis and also of systemic diseases such as cardiovascular disorders and problems in pregnancy.
