Insights

Maternal infections can lead to preterm birth and low birth weight. This review explores the link between periodontitis, a dental infection, and adverse pregnancy outcomes like PTLBW.

Area of Science:

  • Obstetrics and Gynecology
  • Periodontology
  • Reproductive Health

Background:

  • Infections during pregnancy are linked to adverse outcomes, including preterm birth and/or low birth weight (PTLBW).
  • Genito-urinary infections are known contributors to PTLBW.
  • Elevated amniotic fluid inflammatory markers (tumor necrosis factor alpha and prostaglandin E2) suggest infections beyond the genito-urinary tract may cause PTLBW.

Purpose of the Study:

  • To review existing literature on the association between periodontitis and PTLBW.
  • To investigate the potential role of periodontitis as a non-genito-urinary source of infection contributing to adverse pregnancy outcomes.

Main Methods:

  • Literature review of studies investigating periodontitis and pregnancy outcomes.
  • Analysis of evidence linking maternal infections, inflammation, and PTLBW.

Main Results:

  • Studies indicate a potential association between periodontitis and PTLBW.
  • Inflammatory mediators in amniotic fluid suggest systemic effects of localized infections.

Conclusions:

  • Periodontitis may be an independent risk factor for PTLBW.
  • Further research is warranted to elucidate the mechanisms linking periodontitis to adverse pregnancy outcomes.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
The Oral Microbiota01:27

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
