摘要： A sealer for filling a dental root canal which can seal the apex of the root and the root canal perfectly and can be removed with the gutta percha points when refilling is necessary.The sealer of the invention consists of the same basic material as the gutta percha point, so it adheres to the point initimately and firmly and can seal the apex of the root perfectly. The softening temperature of the sealer is about 40.degree.-45.degree. C., so the points and the sealer can be removed same time by heating at low temperature with a heat carrier when refilling is necessary.

摘要： The invention is directed to a compounded thermoplasticized gutta percha or balata and isoprene polymer resin, for filling a dental root canal in an efficient and convenient manner, and a method for preparing the same.The compounded resin includes gutta percha or balata and isoprene polymer and compounding materials including paraffin wax, adapted to compound the gutta percha or balata and isoprene polymer such that they plasticize at a relatively low temperature in the range of 40.degree. C. to 60.degree. C. The use of gutta percha or balata and isoprene polymer, and the relatively low plasticizing temperature, enable the compounded resin to be injected into a prepared dental root canal for filling thereof in an efficient and convenient manner.The method for preparing the compounded resin includes combining, heating and mixing gutta percha or balata and isoprene polymer and the compounding materials to a relatively low temperature in the range of 40.degree. C. to 60.degree. C., at which temperature the compounded materials plasticize, to form the compounded resin.
