Abstract
Novel compositions, especially light curable compositions, are provided which are coherent, but frangible when cured. Preferred compositions comprising a major proportion of inert, preferably inorganic filler material, polymerizable resin and frangibility enhancing material are provided which are light curable. The materials are particularly useful for 'temporary' dental fillings and removable endodontic fillings. The cured materials are easily dissected, comminuted and removed as desired after curing without trauma to the filled teeth.
