On this week’s episode of Fast Facts - Perio Edition your host, Katrina Sanders, RDH takes us through yellow complex bacteria as classified by Sokransky et al in their 1998 classifications.   Quotes:    “These bacteria begin to release chemical signals that will eventually invite the next group of bacteria, encouraging a favorable condition for these orange and red complex bacteria to be able to join the colonization.”   “And so, although these early colonizers may not have pathogenicity associated with periodontal disease, they provide chemical signals and easy adherence or attachment of next layers of bacteria to continue to allow the propagation of diseases of the periodontium.”   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/
