My thesis consisted of both a self-directed study and a creative project. I worked with Dr. Michael Grabow, an endodontist of 20 years, to understand the scientific and technical aspects of root canal therapy. The first phase of the thesis was a review of dental biology, tooth development, morphology, physiology, radiology, and endodontics. The second phase was the creative project in which I learned the technical process of performing a root canal. In this phase, I observed Dr. Grabow execute root canal therapy on live patients and extracted teeth (obtained from an oral surgeon). I then completed root canals of my own on extracted teeth, under the instruction and oversight of Dr. Grabow.
