Relation between the gutta percha root canal filling material and the heating temperature

―Measurement of flow and the pressure reduction test by the apparatus―

Abstract

Abstract : It is assumed that the measurement of the root canal filling material softened by heat foolows JIS T6507 to seek the rate of pressure reduction is ordinary way but we felt doubt about it from results of the various tests we had done, then we took note of measurement using the Reo meter applied the principle of the newtonian fluid and practiced and had the results of which we could be convinced, so we will report them now.
