On this week’s episode of Fast Facts - Perio Edition your host, Katrina Sanders, RDH talks to us about Periodontal diagnostics systems that have been used, and the current system in place highlighting the 1999 classification of “aggressive perio”.    Quotes:    “I think we can all agree that in 1999 things were a bit different, remember, everybody was wearing Tamagotchi's and wearing jelly shoes and slap bracelets and scrunchies. Now we know better.”   “ It was believed that this patient had high quantities of a bacteria called Aggregatibacter actinomycetemcomitans. And so because of that, we basically said, you've got aggressive perio.”   “The AAP published in 2018 that as of right now, there's no evidence of specific pathophysiology, which is just a fancy term for we can't really say patients that have this aggressive rapid rate onset of disease is a patient who has high quantities of a specific type of bacteria. “   Resources:   DentistRX: https://www.dentistrx.com  More Fast Facts: https://www.ataleoftwohygienists.com/fast-facts/    Katrina Sanders Website: https://www.katrinasanders.com  Katrina Sanders Instagram: https://www.instagram.com/thedentalwinegenist/    Sources:   Tonetti, M.
