Oral bacteria attack children early

Champaign, Ill. & Lubbock, Texas, USA: U.S. researchers have found evidence of bacteria associated with early childhood caries in the saliva of infants with no teeth. Their findings suggest that infection with bacteria like Streptococcus mutans in the oral cavity occurs earlier in the development of children than previously thought.

In a comparative analysis using DNA sequencing methods, scientists from the University of Illinois at Urbana-Champaign and two research institutes in Lubbock in Texas identified hundreds of bacteria species in saliva taken from infants whose teeth were still erupting, including those that are involved in the formation of biofilm and ECC.

That's one of the key findings from a survey of American children's oral health, conducted on behalf of Delta Dental Plans Association, the nation's leading dental benefits provider. Most people know that the bacteria in the mouth that causes tooth decay can be transferred from person to person.

Despite international initiatives like the recently held mercury conference in Japan, new regulation towards this issue is also anticipated in the US, where political pressure from anti-mercury groups has convinced the FDA to review their amalgam guidelines.
