Sammanfattning

The oral cavity is an open microbial ecosystem that is continuously influenced by physical, chemical and thermally-derived factors of external origin. The oral microbiome is highly complex and is primarily constituted of bacteria, although virus, protozoa, yeast and archaea may represent minor proportions of the oral microbiome. The development of molecular methods primarily based on analysis of the phylogenetically informative 16S ribosomal RNA (16S rRNA) genes have demonstrated that the oral microbiome is far more complex and diverse, than hitherto anticipated based on result from early culture studies. Thus, it has been shown that the oral microbiota is comprises by more than 700 predominant species, out of which approximately 100-200 species may be isolated from a single subject. At present, 35% of the oral microbiota has yet to be cultivated in the laboratory. The resident oral microbiota is believed to be critically involved in maintenance of oral homeostasis, whereas local compositional alterations as a consequence of ecological perturbations are suggested as determinants of development of periodontitis and dental caries. The purpose of this review is to address modern molecular methods for analysis of oral bacteria, and to discuss a future perspective for development of molecular techniques that can be used chair-side for risk assessment of diseaseprone individuals in the dental clinic.
