Description

technical field

[0001] The present invention generally relates to dental compositions containing organic fluorescent pigments. Background technique

[0002] Over the past few decades, dentists and dental patients have increasingly demanded more aesthetically pleasing dental restorations. High esthetic quality is particularly important for restorations that are easily visible, such as those involving anterior teeth, but is also ideal for restorations involving teeth that are not easily visible.

[0003] The dental industry's increasing focus on aesthetic dentistry has led to the development of dental restoration compositions that more closely mimic the appearance of natural teeth. For example, composite resin materials have been developed that can be used to replace tooth-colored fillings such as metal amalgam fillings to provide more natural-looking dental restorations. In recent years, highly aesthetic composites have become available, such as 3M ESPE TM FILTEK TM Sup...
