Limited to Endodontics, A Practice of Endodontic Specialists We consider it an honor to care for your endodontic needs and greatly appreciate the trust you place in us to do so. Limited to Endodontics was established in 1964, when Drs. Cyril Gaum, Alvin Krakow and Joel Dunsky began what is now a 5-office practice covering greater Boston and beyond. One of the distinguishing factors of our group is our collective dedication to teaching, endodontic research, leadership, and philanthropy in the dental community and beyond. All of our doctors are educationally qualified for or Certified Diplomates of the American Board of Endodontics. Almost all LTE doctors hold teaching appointments at eitherHarvard, BU, or Tufts University Schools of Dental Medicine in addition to clinical practice. Several of our doctors have served these institutions as members of important committees for executive faculty, admissions, and postdoctoral education. Some of our doctors have held the responsibility of department chairs, or obtained directorships of the predoctoral or postdoctoral Endodontic programs and continuing education at these three institutions. One of us has even served as an Assistant Dean for Administration at Harvard.
