Scientists have discovered new allies against tooth decay, an enzyme secreted by bacterial secretions in the oral cavity, and can prevent plaque.The discovery might develop new toothpaste.
We have more than 700 bacteria in our stomatology and reproduce in a warm, humid environment, including Streptocpus mutans, one of the most important strains of dental plaque.It is stuck on the surface of the tooth, and the biofilm produced by the bacteria is in the S.S., in the middle of the present. The mutants decomposes the carbohydrates, and produces acid that erodes the substance of the enamel, and eventually forms a mothhole.Other tenants who live in the mouth are docile, for example, in 2009, the scientists found S., in their tongue and other soft tissue in the mouth of the mouth. The salivarius reduces the S. The biofilm formed by mutants.
Hidenobu Senpuku, of the Tokyo National Center for Infectious Diseases Research, and his team are looking for S. The salivarius is using what material to fight tooth decay.With color layer analysis (chromatography), the molecules that are mixed together can be separated by electrical and molecular size.Next, the research team will separately add S to the different proteins that are separated from the bacteria. In the mutans colony, the growth rate of the colony and the amount of the bio-membrane are measured.As a result, the protein was found to be the strongest biomembrane inhibitor.
addition, scientists have found that a common fungus, Aspergillus niger, produces ready-made FruA, and also has the ability to inhibit plaque.The commercial application of the FreuA, although its amino acid sequence and S. The slight differences generated by the salivarius do not affect the effect of anti-dental plaque.This may shorten the schedule for issuing new toothpaste.
However, this discovery does not allow you to eat all the confectionery.When researchers increase the sugar concentration, S. salivarius will lose the ability to inhibit biofilm generation.This may explain why, in 1996, in rats, Frau was thought to be involved in the formation of tooth decay.
Ellen Davey, a microbiologist at the Forses Institute in Massachusetts,
that the discovery has led to the development of new toothpaste.But she believes that this is not an easy task, because "when the enzyme is to be delivered to the dispensers that you go to, the activity still remains."
