| dental sealants |
The term "dental sealant" or "tooth sealant" refers to a plastic
resin that a dentist bonds into the grooves of the chewing surface of a
tooth as a means of helping to prevent the formation of tooth decay
("cavities").
The groundwork research for tooth sealants was laid back in
the 1950's and 1960's. The first commercially available tooth sealants
were marketed to dentists in the early 1970's.
