Cesarean birth may increase child’s risk for tooth decay

[tirath]

Women with tooth decay and cavities who deliver babies by cesarean section should pay special attention to their newborns’ oral health, according to a recent study published in the Journal of Dental Research.

Researchers at New York University conducted a four-year study of 156 mother-infant pairs; 127 women had vaginal delivery and 29 had cesarean delivery. The women were predominantly African-American, from an inner-city area of Birmingham, Ala., and included in the study beginning in their third trimester of pregnancy.

Women in the study who had cesarean delivery had high levels of Streptococcus mutans infection, as well as decay on an average of one-third of their teeth. A majority of these women had an annual family income of $10,000 or less — a potential barrier to accessing dental care — and a history of sexually transmitted disease.

The research team found that babies delivered by cesarean section were infected by S. mutans almost a year earlier than were infants delivered vaginally. They said this was a significant finding, since previous studies have linked earlier bacterial infection with a higher rate of dental decay in children.

“Vaginally delivered infants offer oral bacteria a less hospitable environment,” said Dr. Yihong Li, associate professor, Basic Science and Craniofacial Biology, NYU College of Dentistry. “They develop more resistance to these bacteria in their first year of life, in part because of exposure to a greater variety and intensity of bacteria from their mothers and the surrounding environment at birth. C-section babies have less bacterial exposure at birth, and therefore less resistance.”

The findings suggest that mothers who have dental decay should inform their dentists if they have cesarean delivery because of the potentially higher risk that the child also will develop caries, said Dr. Li.

Researchers say further study is needed to determine if cesarean births can be linked to earlier acquisition of S. mutans and other oral bacteria in a broader cross-section of the population, and if a higher incidence of decay follows.

are there any protocols recomended to overcome this problem?

routine oral hygiene methods whatever should be put in place to treat children prone to dental decay will work. Brush thrice a day, cut down on sweets, use a disclosing solution, fluoride applications, sealants etc.

C-section ‘baby teeth decay risk’

The study looked at 156 babies.
Babies born by Caesarean section are more at risk of tooth decay, research suggests.
A New York University team found C-section babies were infected by a cavity-causing bacterium nearly a year earlier than those born naturally.

A study of 156 babies found those born vaginally were exposed to more bacteria during birth and built up resistance.

But the authors accepted a range of social factors also played a role, the Journal of Dental Research said.

The team found that on average the 29 C-section birth babies monitored as part of the study showed the first signs of the appearance of the bacterium, streptococcus mutans, after 17 months.

The earlier it gets a hold, the more damage it can cause.

In comparison, the 127 natural birth babies only developed the bacterium at nearly 29 months of age, study said.

Streptococcus mutans grows on the surface of teeth and just above the gum line where it turns foods into acids. It is predominantly transmitted to babies from their mothers because of the close contact they have.

Previous studies have found that the earlier that streptococcus mutans develops, the higher the rate of cavities in children.

More than one in five births in the UK at the moment are via C-section.

Lead researcher Dr Yihong Li said: “Vaginally-delivered infants offer oral bacteria a less hospitable environment.

“They develop more resistance to these bacteria in their first year of life, in part because of exposure to a greater variety and intensity of bacteria from their mothers and the surrounding environment at birth.

Exposure

“C-section babies have less bacterial exposure at birth, and therefore less resistance.”

But he also pointed out that the C-section mothers in the study also had higher levels of tooth decay, a history of sexually transmitted infections and low family income, all of which could have contributed to the findings.

Roy Russell, professor of oral biology at the University of Newcastle, said it was important to find ways of minimising infection of the bacterium.

“It is the main decay causing bacterium and the earlier it gets a hold, the more damage it can cause.”

He suggested the findings may persuade people that natural birth was best, but said other factors such as diet and oral care played a role that could cancel out high rates of infection.

an interesting study.

dentists and gynaecologists must inform expecting mothers about this problem.
