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.
Fluoride varnish is a highly concentrated form of fluoride that is applied to the tooth's surface by a dentist, dental hygienist or other dental professional, as a type of topical fluoride therapy. [1] It is not a permanent varnish but due to its adherent nature it is able to stay in contact with the tooth surface for several hours.
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.
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [ 3 ] ) and polyacrylic acid , an ionomer .
T-cell immunity might outlast antibody immunity—at least in some patients. Soon, you can find out your truth for yourself.
COVID-19 immunity, whether it’s from catching COVID or getting vaccinated against the virus, doesn’t last forever, explains John Sellick, D.O., an infectious disease expert and professor of ...
Dental caries is a dental biofilm-related oral disease associated with increased consumption of dietary sugar and fermentable carbohydrates. When dental biofilms remain on tooth surfaces, along with frequent exposure to sugars, acidogenic bacteria (members of dental biofilms) will metabolize the sugars to organic acids.
