A caries vaccine is a vaccine to prevent and protect against tooth decay. [1] Streptococcus mutans ( S. mutans ) has been identified as the major etiological agent of human dental caries. The development of a vaccine for tooth decay has been under investigation since the 1970s.
Glass ionomer cements act as sealants when pits and fissures in the tooth occur and release fluoride to prevent further enamel demineralisation and promote remineralisation. Fluoride can also hinder bacterial growth, by inhibiting their metabolism of ingested sugars in the diet. It does this by inhibiting various metabolic enzymes within the ...
It does not resorb, and is biocompatible, forming a seal against the tooth material that minimizes leakage. [1] Originally, MTA was dark gray in color, but white versions have been on the market since 2002. Bismuth oxide, which was added as a radioopacifier (to make the filling stand out on X-rays), [citation needed] can discolour the teeth. [3]
The majority of clinical studies indicate the annual failure rates (AFRs) are between 1% and 3% with tooth colored fillings on back teeth. Root canaled (endodontically) treated teeth have AFRs between 2% and 12%. The main reasons for failure are cavities that occur around the filling and fracture of the real tooth.
On Thursday, the companies filed for full approval of their COVID-19 vaccine with the U.S. Food and Drug Administration to include adolescents aged 12 to 15. Pfizer to test third dose of COVID-19 ...
It does not possess anticariogenic effects, is not adherent to tooth structure, and acquires a moderate degree of intraoral solubility. However, zinc phosphate cement can irritate nerve pulp; hence, pulp protection is required but the use of polycarboxylate cement (zinc polycarboxylate or glass ionomer) is highly recommended since it is a more ...
BioNTech and Pfizer said on Wednesday a three-shot course of their COVID-19 vaccine was shown to generate a neutralising effect against the new Omicron variant in a laboratory test. In the first ...
T-cell immunity might outlast antibody immunity—at least in some patients. Soon, you can find out your truth for yourself.
