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.

La présente invention a pour objet une méthode d'application d'une préparation dentaire sur des surfaces dentaires. La préparation dentaire, qui comprend une résine polymérisable et un composé fluorescent, est appliquée à la surface d'une dent puis durcie. La préparation est préférentiellement employée en tant que joint dentaire pour l'obtention d'une finition de surface dure et brillante sur une dent. L~irradiation du joint avec un rayonnement ultraviolet provoque l'émission par le joint d'une intense lumière fluorescente. Le joint reprend immédiatement sa couleur naturelle lorsqu'il n'est plus exposé à la lumière ultraviolette.
