| 摘要 |
A pre-packaged dental treatment system (100) including dental treatment devices (102) each having a barrier layer (106) configured for placement over at least a portion of a person's teeth, a dental treatment composition (108) (e.g., a bleaching composition) disposed adjacent to the barrier layer (106), and a sealed packaging container (104) within which the dental treatment devices (102) are disposed. At least a portion of the packaging container (104) includes a laminated polymer material that is substantially impervious to water molecules, which prevents the dental treatment composition from drying out. The laminated polymer material is optionally also a barrier to oxygen molecules.
