摘要：A dry type adhesive device for teeth whitening in which a peroxide toothwhitening agent is stabilized is disclosed. The dry type adhesive device for toothwhitening comprises a matrix type adhesive layer and a backing layer wherein theadhesive layer contains a peroxide as a teeth whitening agent and a hydrophilic glassypolymer as a base polymer so that the hydrophilic glassy polymer provides strongadhesion to teeth when hydrated at the enamel layer of the teeth in the moist oral cavityand the whitening agent is released. In particular, although the dry type adhesive deviceis touched with the hands or contact the skin during attaching to the teeth prior tohydration, no stickiness and releasing of the whitening agent takes place, thus being safe.In addition, since the dry type patch has strong adhesive strength to the teeth andexcellent adhesion maintenance after being hydrated and attached to the teeth, it canremain attached to the teeth for a long time and thus exhibits excellent whitening effecteven low concentrations of a whitening agent. Furthermore, the dry type adhesive devicecan provide excellent whitening within a short period of time.
