Stephen L. Buchanan, D.D.S.


Dr. Buchanan currently serves as an assistant clinical professor at the University of Southern California School of Dentistry and the University of California at Los Angeles School of Dentistry. He also maintains a private practice limited to endodontics and implant surgery in Santa Barbara.

He began pursuing three-dimensional anatomy research early in his career. In 1986, he became the first person in dentistry to use microcomputed tomography technology to show the intricacies of root structure.

In 1989, he established Dental Education Laboratories and subsequently built a state-of-the-art teaching laboratory devoted to hands-on endodontic instruction where he continues to teach. Through Dental Education Laboratories, he has lectured, conducted participation courses around the world, published numerous articles, and produced the award-winning video series The Art of Endodontics.

In addition to his activities as an educator and practicing clinician, he holds a number of patents for dental instruments and techniques. Most notably, he was the first to introduce variable-tapered instruments for use in endodontic therapy and pioneered a system-based approach to treating root canals.

In 1978, he received his dental degree and was valedictorian of his class at the University of the Pacific Arthur A. Dugoni School of Dentistry, and completed the endodontic graduate program at Temple University in Philadelphia, Pa., in 1980.

He is a Diplomate of the American Board of Endodontics and a Fellow of the International and American Colleges of Dentists.
