1. A dental medicament applicator comprising:
a placement device sized for insertion at a dental site, the dental site including an interproximal site with a dental caries, the placement device comprised of hydroxypropyl methyl cellulose (HPMC) polymers, the placement device including a central body, a first wing, and a second wing;
the first wing providing subterminal opposition surfaces in which palmar surfaces of a thumb and an index finger can hold the first wing therebetween, the first wing being sized to bend around the interproximal site so that, when bent, the first wing engages a dental surface adjacent the dental site and stabilizes the central body over the dental caries, the first wing being free of a topical substance for treating incipient lesions;
the second wing providing subterminal opposition surfaces in which palmar surfaces of a thumb and an index finger can hold the second wing therebetween, the second wing being sized to bend around the interproximal site so that, when bent, the second wing engages a dental surface adjacent the dental site and stabilizes the central body over the dental caries, the second wing being free of the topical substance;
at least one active matrix secured to the front of the central body, the at least one active matrix comprised of pullulan polymers containing the topical substance;
each of the first wing and the second wing having a larger surface area than the at least one active matrix;
the placement device, in response to being physically affixed to the dental site and bent around the interproximal site and the adjacent dental surfaces, dissolving at a first controlled rate; and
the at least one active matrix, in response to the central body being physically affixed over the dental caries, transitioning to a gelatinous state while delivering the topical substance to the dental caries at a second controlled rate that is slower than the first controlled rate, the gelatinous active matrix thereafter dissolving and being bio-reabsorbed,
whereby the dental medicament applicator completely dissolves following dissolution of the placement device at the first controlled rate and delivery of the topical substance at the second controlled rate.
