sealant

You must have a sealant painted on your tooth or risk bacteria creating holes in it.

What ensues is nearly two hours of the false starts and second-guessing that romances use as sealant.

In sealant programs, dental professionals visit schools to apply a thin, protective coating to the surface of teeth that hardens and safeguards against decay.

"Our longitudinal study reaffirms that both sealants and SDF are effective against cavities. SDF is a promising alternative that can support school-based cavity prevention -- not to replace the dental sealant model, but as another option that also prevents and arrests decay," said Ryan Richard Ruff, PhD, MPH, associate professor of epidemiology & health promotion at NYU College of Dentistry and the study's first author.

In another application, they layed down a thin chitosan film on a tough gel that was already placed on an injured pig aorta ex vivo as a wound sealant to increase the overall strength of the bandage, which was exposed to the cyclical mechanical forces of blood pulsing through the vessel.
