<p>PROBLEM TO BE SOLVED: To provide a dental filler and a dental composition which have sufficient strength and a good aesthetic property, and can discharge fluoride ion for a long period of time.SOLUTION: A dental filler F used for a dental composition comprises a core material part H and a side material part S surrounding the core material part H. The core material part H is an inorganic filler containing fluoride ions. The side material part S comprises at least a first layer and a second layer. The first layer is formed in a network structure in which a polymer is crosslinked by using silane coupling material containing a polymerizable group. The second layer is formed in a film shape by using a phosphoric acid monomer and a polymerizable monomer. From an inside center to an outside of the dental filler F, the core material part H, the first layer and the second layer are arranged in this order.</p> |
