In connection with insertion of a post into a root canal, a simultaneous curing of the tangible sealing ma1terial aggregate is accomplished. Gutta percha or other sealing material is removably attachable to the apical end of the post and heat or other energy is applied to the post, either before and/or after the post is inserted into the root canal of the tooth being treated, to plasticize and condense the tangible sealing material aggregate. The sealing material is removably integral with the post, or removably attached to the post. In other cases, the tangible sealing material aggregate is provided in a tapered tip and is attached to the bottom of the post without heat or other energy sources, or by condensation, and is therefore attached as an uncondensed single point fill. When placed in the root canal, the tangible sealing material aggregate tip is held in place by typical root canal cements, such as eugenol based cements, resin based cements and glass ionomer cements.
