  • Dental restoration method and composition therefor
    Patent number: 4600389
    Abstract: Dental work such as in fillings, restorations, crowns and tooth glazing is assisted by use of a flourescent compound as the dental composition. The compound is made up of a rare earth chelated flourescent compound incorporated in microbeads which in turn are incorporated in a conventional composition. Observation of the site under ultraviolet radiation enables precise location of the site boundaries as excess material is removed or as the site is observed for wear after a period of time.
