Externs to the Advanced Education Program in Endodontics attend seminars, case presentations, appropriate lectures, and literature reviews with both the first and second year endodontic residents. The specific topics will be dependent on the time of year of their externship. Normally these externships occur during the spring semester. Externs will also spend a significant amount of time observing the treatment of patients in the graduate clinic. Preclinical exercises on extracted teeth will be available. Externs will also be allowed to observe and, if appropriate, assist in any research in progress in the department. Externships with the Department of Endodontics are offered for one week only.
