Tooth Decay now have gone,a Vaccine Made By Scientist!!!

KEEPING CAVITIES AWAY

Regular visits to the dentist are an important part of keeping your teeth healthy. But what if you could give your oral health a boost by receiving a vaccine on top of your regular dental care routine? Researchers from the Wuhan Institute of Virology (WIOV) of the Chinese Academy of Sciences are working on such a vaccine, and their study has just been published in Scientific Reports.

Led by WIOV scientist Yan Huimin, the researchers tested a fusion of proteins to prevent the development of dental caries. Better known as dental cavities, caries is caused by the bacteria Streptococcus mutans (S. mutans).

In previous studies, the Chinese researchers had attempted to protect against caries by fusing the recombinant PAc (rPAc) proteins of S. mutans with the C-terminal of E. coli-derived recombinant flagellin (KF) proteins. Though effective at protecting against caries, this protein fusion was found to produce unwanted side effects, including possible inflammatory injury.

In an attempt to lessen these side effects, the researchers developed KFD2-rPAc, a second-generation of their flagellin-rPAc fusion protein.

In lab tests using mice and rats, a vaccine prototype of the protein fusion was administered through the nasal cavities. When mice without caries received this vaccine, it conferred a 64.2% prophylactic efficacy, and in those mice that had already developed caries, the vaccine produced a 53.9 percent therapeutic effect.

Overall, the protein was shown to retain the original version’s high level of protection against caries, while producing fewer side effects.

A GLOBAL PROBLEM

According to the World Health Organization (WHO), dental carries remains a major health problem in most industrialized countries despite recent advances in oral healthcare. Some 60 to 90 percent of schoolchildren, as well as adults, are known to suffer from dental caries, so clearly, a huge number of people could benefit from a vaccine that prevents their formation.

In previous studies, the Chinese researchers had attempted to protect against caries by fusing the recombinant PAc (rPAc) proteins of S. mutans with the C-terminal of E. coli-derived recombinant flagellin (KF) proteins. Though effective at protecting against caries, this protein fusion was found to produce unwanted side effects, including possible inflammatory injury.
