So, this bit of an impression serves as a reminder to me of how unlearned I truly am. To assist you in developing some perspectives on the history of lasers in dentistry, the following material will be presented: 1963 - "I Start on the Teeth" from the Laser Laboratory Medical Center, University of Cincinnati. — 1987 "Laser Dentistry" (my current review) from the Laser Laboratory, Medical Center, University of Cincinnati. - 1991 - "NonSurgical Medicine" (my book) with a chapter by G. C. Willenborg, D.D.S.M.M.F.F.I.C.D., Lasers and Electro-optics in Dentistry, a comprehensive article, pages 253-292. - 1995 - "A Future For Laser Dentistry" from the Naval Medical Center, San Diego, California.
