Endodontic core and post are disclosed, forming an integral unit of which the post, adapted to be anchored in the respective root canal, is provided with, preferably, four wings perforated to allow passage of cement or the like through same in order to enhance the strength of embedding of the post in the root canal. The radial wings of the post are disposed each in a recess which is reamed by utilizing a special guiding post which is also a part of the present invention. In order to further enhance the strength of the bond between the core and the post in the respective root canal, an extension beam, preferably of a cross-shaped cross-sectional configuration, is adhesively secured to the free end of the post to form a "winged" extension of the post itself. The wings of the beam extension are also perforated for the same reason.
