20080206715 | COLOR CHANGING DENTAL ADHESIVE COMPOSITIONS AND RELATED METHODS AND KITS - Methods, compositions, and kits for use in facilitating detection and removal of dental adhesives while minimizing and/or eliminating removal of adjacent tooth tissue. A pH sensitive color changing component (i.e., an acid/base indicator) is included within a dental adhesive composition or an activating wash composition. The adhesive composition is used to bond a dental appliance (e.g., a provisional restorative appliance or an orthodontic bracket) to a tooth. When it becomes necessary to remove the dental appliance, selective removal of the dental adhesive while minimizing and/or eliminating removal of enamel or other adjacent tooth tissue are facilitated because of the inclusion of a pH sensitive color-changing component within the dental adhesive or activating wash composition. The adhesive changes from a first color having low contrast relative to adjacent tooth tissue to a second color having greater contrast relative to adjacent tooth tissue upon application of the activating wash. | 08-28-2008 |
