Dentists Find Additional Bacteria Species Involved with Tooth Decay
An interesting article titled “Selenomonas sputigena acts as a pathobiont mediating spatial structure and biofilm virulence in early childhood caries,” written by Hunyong Cho and et. al. appears in Nature Communications (vol. 14, no. 1, 2023). The article seeks to study if other bacteria besides Streptococcus mutans are involved with tooth decay and cavities in children, also known as dental caries. Prior to the study it was believed that S. mutans and other acid-making bacteria are adequately removed by teeth-brushing and oral care, and this creates a protective biofilm, or plaque, on teeth. If the plaque is left in place for too long, bacteria consumes sugars from food and drinks and coverts them to acidsm which erode the enamel of affected teeth, in time creating cavities. The article investigated the role of Selenomonas sputigena (S. sputigena) in early cavities in children. S. … Read more
