摘要： A thermoplastic dental filling composition is disclosed, comprising a polymer component containing trans-1,4-polyisoprene and an ethylene/vinyl acetate copolymer resin and an insoluble or sparingly soluble inorganic filler. The filling composition of the invention has similar softening operation properties to natural guttapercha and has a high tensile strength and, therefore, it can be suitably used as a root canal filling material. Further, a composition comprising the above-described dental filling composition having a wax-like component added thereto is used as a temporary filling material.
