Insights

Low-dose xylitol tablets did not significantly reduce mutans streptococci (MS) colonization or caries in preschoolers. Maternal MS levels influenced child colonization in the control group, but not in the xylitol group.

Area of Science:

  • Pediatric Dentistry
  • Microbiology
  • Preventive Dentistry

Background:

  • Mutans streptococci (MS) are primary causative agents of dental caries.
  • Early childhood caries (ECC) poses a significant public health challenge.
  • Xylitol is a sugar substitute with known anticariogenic properties.

Purpose of the Study:

  • To assess the efficacy of daily low-dose xylitol tablets in preventing mutans streptococci colonization and caries development in preschool children.
  • To investigate the relationship between maternal and child MS colonization.
  • To evaluate the impact of xylitol intervention on caries prevalence.

Main Methods:

  • A randomized, single-blind, prospective study involving 132 healthy 2-year-olds.
  • Children were assigned to either a xylitol tablet group or a control group for 1.5 years.
  • Mutans streptococci levels and caries prevalence were monitored throughout the 2-year trial.

Main Results:

  • No statistically significant differences in MS colonization were observed between the xylitol and control groups.
  • Maternal MS levels correlated with child colonization in the control group, but not in the xylitol group.
  • While caries prevalence was lower in the xylitol group at age 4, the difference was not statistically significant.

Conclusions:

  • Low-dose xylitol tablet supplementation is not supported as an effective caries prevention strategy for preschool children.
  • Further research may be needed to determine optimal xylitol dosage and delivery methods for pediatric caries prevention.

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,...

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...

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...

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...
