Abstract
A method of applying a dental composition to tooth surfaces is provided. The dental composition, comprising polymerizable resin and fluorescing compound, is applied to a tooth surface and cured so that it hardens. The composition is preferably used as a dental sealant that provides a hard, glossy surface finish over a tooth. Upon irradiating the sealant with ultraviolet light, the sealant exhibits a bright fluorescent glow. The sealant reverts immediately to its natural color when it is no longer exposed to the ultraviolet light.
Claims10
A method of applying a dental composition to an area of a tooth surface, comprising the steps of:
- a) providing a dental composition comprising polymerizable resin and fluorescing compound;
- b) applying the composition to a tooth surface;
- c) curing the composition so that it hardens;
- c) irradiating the composition with a light source emitting light at a wavelength in the ultraviolet spectrum of about 200 to about 400 nm;
- d) visually identifying the composition by observing emitted fluorescence having a wavelength in the visible spectrum of greater than about 400 nm so as to distinguish the area of the tooth surface containing the composition from remaining natural areas of the tooth surface.
