PROBLEM TO BE SOLVED: To provide a relatively low cost dental pulp model used as training material for dental root canal treatment, capable of providing integral training of a crown cutting process, a pulp bleeding cleaning process, pulpectomy and root canal length measurement, and shortening self-learning time by providing continuous training of the treatment processes of the root canal treatment.SOLUTION: In a cylindrical high-functional dental pulp model, a crown 3 is formed of an artificial tooth for denture and a pulp part 2 is made of transparent epoxy resin, in order to reproduce a hardness difference between the crown and the pulp part. Further, the pulp part is made waterproof whose shape is cylindrical and which is covered with a rubber waterproof cap, and is used after being lightly pressed and fixed in a working stand 1. Dummy blood enclosed inside the dental pulp model and a joint space of the working stand are filled with a substance or a physiological saline solution having electric properties of the same level with a human body and turned into an electrically conducted state, thereby making electric measurement of a root canal length possible. |
