New parents have one more reason to pay attention to the oral health of their toothless babies. A recent University of Illinois study confirms the presence of bacteria associated with early childhood caries (ECC) in infant saliva.
ECC is a virulent form of caries, more commonly known as tooth decay or a cavity. Cavities are the most prevalent infectious disease in U.S. children, according to the Centers for Disease Control and Prevention.
"By the time a child reaches kindergarten, 40 percent have dental cavities," said Kelly Swanson, lead researcher and U of I professor of animal science. "In addition, populations who are of low socioeconomic status, who consume a diet high in sugar, and whose mothers have low education levels are 32 times more likely to have this disease."
Swanson's novel study focused on infants before teeth erupted, compared to most studies focused on children already in preschool or kindergarten after many children already have dental cavities.
"We now recognize that the "window of infectivity," which was thought to occur between 19 and 33 months of age years ago, really occurs at a much younger age," he said. "Minimizing snacks and drinks with fermentable sugars and wiping the gums of babies without teeth, as suggested by the American Academy of Pediatric Dentistry, are important practices for new parents to follow to help prevent future cavities."
In addition, his team used high-throughput molecular techniques to characterize the entire community of oral microbiota, rather than focusing on identification of a few individual bacteria.
"Improved DNA technologies allow us to examine the whole population of bacteria, which gives us a more holistic perspective," Swanson said. "Like many other diseases, dental cavities are a result of many bacteria in a community, not just one pathogen."
Through 454 pyrosequencing, researchers learned that the oral bacterial community in infa
