A new look at the origin of cavities in teeth

Bacteria help form acids

In cases of life-threatening septicemia, an abundance of these bacteria has been observed in the biofilms in the mouth when the infection is at its peak.

S. sputigena appears to interact efficiently with S. mutans, helping these bacteria produce acid that attacks enamel and dentin.

trapped by glucans

S. mutans is particularly good at producing glucans, which have a reinforcing effect on dental plaque formation. S. sputigena, which can move across surfaces, is captured by glucans.

When this happens, S. sputigena reproduces and forms the established cell, honeycomb (octagonal) The “superstructure”, which encapsulates and protects S.

Together they make tooth decay worse

Together, these two bacteria form an aggressive pair that stimulates acid formation, which leads to the spread of tooth decay.

The researchers’ discovery provides an entirely new insight into the development of dental caries and may help target prevention of this condition in the future.

In addition, the research revealed new and unknown mechanisms that underlie the development of bacterial microfilm (biofilm), which may be relevant in other clinical contexts.
