Author Interviews, Dental Research / 22.10.2019 Interview with: Robert Margolskee, MD, PhD Director and President Monell Center Adjunct Professor, Department of Systems Pharmacology and Translational Therapeutics University of Pennsylvania Perelman School of Medicine What is the background for this study? What are the main findings? Response: We found chemical-sensing cells in the gums that protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth. With the help of bitter taste receptors that also detect byproducts from harmful bacteria, these special gum cells trigger the immune system to control the amount and type of bacteria in the mouth. This knowledge could one day lead to personalized dental treatments against gum disease. Periodontitis is a serious gum disorder caused by an imbalance in the bacteria and other microorganisms of the mouth. We hope that our new information can help to combat this sixth-most prevalent infectious disease and most common cause of tooth loss worldwide. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, Dental Research / 24.10.2018 Interview with: "Still from "My Dental Hell(th)"" by littledropofpoison is licensed under CC BY 2.0Rita Del Pinto, MD University of L'Aquila Department of Life, Health and Environmental Sciences, L'Aquila - Italy What is the background for this study? What are the main findings? Response: There is a wealth of literature in support of a role for inflammation behind cardiovascular risk factors and diseases. One relatively poorly explored field is that of oral diseases, namely periodontitis, as a potential source of low-grade, chronic inflammation. Previous studies had described a beneficial effect of periodontal treatment on blood pressure; we extended current knowledge with our findings on over 3600 treated hypertensive adults with and without periodontitis, showing a significant benefit over systolic blood pressure behavior and control in the presence of a good periodontal health.  (more…)
