Some bacteria of the oral cavity can protect against caries
December 27, 2010
Tooth decay is the most common infectious disease worldwide and, although it is influenced by multiple factors Recent studies have identified bacteria in the oral cavity to protect against microorganisms that cause decay, as highlighted during the symposium 'Microbiome: discovering the last organ of the body', organized by the Lilly Foundation in Madrid.
As explained by Dr. Alex Mira, Senior Research Centre Valencia Public Health, "people do not get cavities have a number of different bacteria that produce antibiotics and specifically kill the bacteria that cause tooth decay."
Thus, studies by isolating the key genes of individuals without caries have shown that these bacteria inhibit the growth of cariogenic bacteria, suggesting that the use of these chains of commensal bacteria as probiotics might promote oral health and prevent dental caries.
human dental plaque is composed of a complex microbiota in which live between 400 and 500 species of microorganisms, "the vast majority of them is necessary who are there because they are part of the natural balance, "Dr. Mira concrete.
Thus, while bacteria have been identified that may be beneficial, the next step in research notes this expert is" whether you can replace the oral microbial flora of a person on the other composed of healthy bacteria flora in balance in the mouth. "
On the other hand, the research team of Dr. Mira has shown that cavities are not caused by a single bacterium but there are others that "we also produce acid and therefore may be involved in decay," he explains.
