The Changing Scene of Practicing Dentistry: A Survey of the Past 200 Years.

If one could be a patient repeatedly, every twenty-five years, starting in 1825, the evolution and comparison of dental care and dental practice would be historically meaningful. Such a time travel, as a perpetual patient through 200 years, is the purpose of this paper. The changes that occurred over 200 years provide a sense of the progress in treating patients and the transformation of a painful and dreaded experience to a highly sophisticated painless profession.
