Baby's Death Linked to Pregnancy-Related Gingivitis

Hi everyone,

In a landmark case, researchers were contacted by a 35 year old woman who had recently delivered a still-born baby at 39 weeks and 5 days gestation: full term. Postmortem microbial studies found the presence of F. nucleatum in the lungs and stomach. The baby died from a septic infection and inflammation caused by bacteria.

Researchers used DNA-cloning technologies found a match between the oral bacteria of the mother and the bacteria in the baby's lungs. Bleeding associated with gingivitis allowed the bacteria to enter the bloodstream and work its way to the placenta. The mothers immune system usually takes care of this situation, but she also experienced a upper respiratory infection which may have weakened her immunity enough to allow the bacteria to colonize the uterus.

Dental Care During Pregnancy

Hey everyone,

I was just reading some of the latest findings/summaries in the Ontario Dentist Journal about pregnancy and dental care. Some interesting points:

1. 50% of women experience gingivitis during pregnancy due to increased hormone production
2. Roughly half of those women do not seek dental care
3. A study of 823 women at 13-21 weeks did not show any adverse fetal outcomes when periodontal disease was treated by scaling and root planing using local anaesthetic
4. Local anaesthetics are generally safe during pregnancy. However proper aspiration is particularly important to prevent inadvertent intravascular injection
5. Health Canada recommends that amalgam fillings should not be placed or removed during pregnancy. This approach is conservative since studies have failed to show an increased incidence of birth defects, spontaneous abortions, neurologic or infertility problems.
6. Prenatal x-rays are a small dose of radiation that has not been shown to be associated with any adverse fetal abnormalities
