Summary

Dr. Scott B. McClanahan received a B.A. in 1974 and D.D.S. in 1981 both from the University of North Carolina at Chapel Hill. In 1981, he entered the U.S. Navy as a dental officer. In 1986, Dr. McClanahan was selected by the Navy for civilian specialty training and completed his certificate of residency in endodontics at Northwestern University Dental School as well as a M.S. from Northwestern University in 1989. After three tours of duty as a clinical endodontist, Dr. McClanahan joined the faculty of the Endodontics Department at the Naval Postgraduate Dental School, Bethesda, MD in 1998 and in 2001, assumed the responsibilities of Chairman of the Endodontics Department and Director of the Advanced Specialty Education Program in Endodontics. He retired from active duty in September 2005. Dr. McClanahan joined the faculty at the University of Minnesota, School of Dentistry as an Associate Professor in November of 2005. He is a Diplomate of the American Board of Endodontics.
