Abstract : The Obturation System is the method of injecting the thermo-plastic Obturation Gutta in the root canal with the exclusive use injector and filling it by the vertical condensation method with pluggers.

 But this method is apt to become over obturation when the narrow part of the apex of root is above ＃35. In this case, the following method is recommended that after the apex of root is sealed with the apical cone technique, the upper part is filled by the Obturation System.

 This time, we have standardized the apex of root preparing by ＃50 apical reamer using extracted teeth and the sealing ability of the apex of root is compared the case that the root canal is filled by the Obturation System only using the hard Obturation Gutta without a sealer with the case that the apex of root is filled by both the apical cone technique using a marketing guttapercha cone and the Obturation System.

 We have obtained the results that the Obturation System using the Obturation Gutta only has the most excellent sealing ability.
