Dental podcast: Welcome to DentalTalk. I'm Dr. Phil Klein. Today we'll be addressing the controversial question, "When we restore teeth due to caries, is it appropriate as the final step in the restorative procedure to apply a fluoride varnish?" We will explore the thinking behind this question and how it relates to the prevention of secondary caries. Our guest is Dr. Jean Creasey, a former dental hygienist who found success in dental practice by focusing on prevention first. She currently teaches Ethics and Professionalism at California's newest dental school, California Northstate College of Dental Medicine.
