ABSTRACT:
A dental composition can include at least one polymerizable resin and at least one anti-stokes up converter. Alternatively, a two-part composition can include at least one dental composition configured for placement onto a person's tooth, and at least one anti-stokes up converter to be combined with the at least one dental composition. The dental composition can be formulated to blend with a person's tooth, and also be capable of changing color to be distinguishable from the tooth when exposed to long wavelength light. The dental composition can be used in a method for performing a dental procedure by applying the dental composition to a tooth, and exposing the dental composition to long wavelength light. Accordingly, the dental composition can aid a dental professional in distinguishing between the location of the dental composition and the tooth.
