Dental researchers target bacterial communication to shape healthier oral microbiomes

Bacterial communication — known as quorum sensing — allows microbes to detect their population density and coordinate community behaviour. (iStock)

Dental researchers are exploring how bacterial “conversations” in the mouth shape the ecology of dental plaque — and how interrupting those signals could favour a healthier microbial balance without harming beneficial species. A team from the College of Biological Sciences and the School of Dentistry at the University of Minnesota has detailed how bacterial communication … Read more

A novel means of modulating the oral microbiome to promote dental health

stein-thumbnail alternate text for this image

Oral dysbiosis, a key driver of many oral diseases that impact over three billion people worldwide, is the shift away from health-associated homeostatic microbial populations that inhabit the oral cavity.1-3 Indeed, the oral microbial consortia associated with dental health is characteristic of having high diversity, both in genetic composition and in metabolic capability.4-7 Antibiotics, chronic antiseptic exposure, … Read more
