Endodontic morphology. II. A radiographic analysis.
Radiographs of 164 extracted human teeth were examined under magnification subsequent to the infusion of a radiopaque contrast medium under vacuum into their empty canal systems. An analysis of the results was made from the recorded statistics, and some conclusions have been drawn from these. The form and number of canals generally conformed to those of the roots which housed them, with some exceptions. The presence of two canals in the mesiobuccal roots of maxillary first molars and the incidence of lateral, accessory, and furcation canals have been noted. The role of the endodontist in the treatment of teeth with such anatomic features was discussed.
