For years, most schools and academic institutions taught that the gutta-percha point should end at the radiographic apex of the root—i.e., the zenith or highest point of the root as seen on the clinical x-ray. Yet when we did that, a certain percentage of patients felt uncomfortable and could not easily bite on their endodontically treated teeth. And there were other problems. Dr. Allan S. Deutsch says we must change our concept of endodontic beauty. Optimum endodontic obturation should actually be a fill that looks 0 to 2 mm short of the radiographic apex for maximum success.
