Uncovering New Anticariogenic Agents

by Zachary R. Conley zconley@email.arizona.edu Introduction: The formation of dental plaque involves a rather ordered pattern of bacterial colonization. As the teeth erupt (or if they are cleaned), surfaces of the enamel are first coated with conditioning film which is characterized by molecules from the host (e.g., saliva) and from the bacteria (e.g., secreted by-products). Early colonizers will grow and change the local conditions to increase its suitability for more discriminating species which colonize later, attaching to previously bound bacteria by adhesion-receptor mechanisms.  Biofilm efficiently produce acid via their metabolism of carbohydrates, leading to demineralization of hard dental tissue. In order to prevent caries, it is essential to set our targets on the formation process of dental biofilms. 1  Anticariogenic compounds that are able to target the mechanisms of biofilm formation are gaining interest in recent history, and provide effective supplements...

How Prepared Are You for a Medical Emergency?

Dr. Catharine Goodson catharine@catharinegoodsondds.com www. catharinegoodsondds.com   "One day you will wake up and there won't be any more time to do the things you've always wanted. Do it now…" — Paulo Coelho In March 2011 what was supposed to be a routine wisdom tooth extraction on a 17-year-old girl from Woodstock, Maryland, went horribly wrong. Jenny Olenick had been given the standard dose of anesthesia, but it didn’t sedate her adequately. The anesthesiologist administered more, and the procedure began. Then Jenny began experiencing bradycardia, or a slowing heart rate, and the oxygen saturation in her blood started dropping. Soon she went into hypoxic arrest. Emergency responders were called and restored Jenny’s pulse within four minutes of their arrival, but the damage had been done. Jenny was rushed to the hospital, where she died after being in a coma for a week. The autopsy showed that Jenny had brain edema and acute hypoxic-ischemic encephalopat...
