Behavioral Interventions for Periodontal Disease

An interesting article titled “The effect of risk communication on periodontal treatment outcomes: A randomized controlled trial” appears in the 2019 edition of the Journal of Periodontology written by Asimakopoulou et al. The article explores using psychological interventions to reduce gum disease. In the article the authors were inspired by a Capability-Opportunity-Motivation-Behavior model to improve clinical, psychological, and self-reported behavioral outcomes. Specifically the authors sought to assess such things as periodontal probing depths and bleeding on probing, self reported teeth brushing, and thoughts about periodontal disease. The authors randomized 97 adults with moderate peridontal disease who presented at King’s College London in the U.K. into three treatment groups: 1) usual dental treatment, 2) dental treatment and a report on their disease risk and 3) dental treatment, a report, and a program to improve their dental health. The participants had data … Read more

Photoacoustic Imaging for Periodontal Health in Humans

Recently on this website research exploring using photoacoustic imaging for periodontal probe depths from University of California, San Diego, using swine models was discussed. This same group has since published an article titled “Photoacoustic imaging for monitoring periodontal health: A first human study,” by Moore et al. in Photoacoustics (vol. 12, pp. 67-74, 2018, published online November 01, 2018) where they show that a photoacoustic-ultrasound imaging approach can image the full depths and geometries of pockets in healthy human adults. Traditionally ultrasound uses the principle sound in and sound out but the photoacoustic-ultrasound approach uses light in, sound out. The advantageous of such an approach over traditional radiography is that it can image soft issue and that it does not cause ionizing radiation. The conventional method for dentists to monitor gingival health in humans is with a periodontal probe. This … Read more

Photoacoustic Imaging for Periodontal Probing Depth

Engineering research at the University of California San Diego has led to a technique that could update how teeth and gums are imaged. Researchers combined squid ink with light and ultrasound to create a new dental imaging method to examine a patient’s gums in a more comprehensive and accurate way than existing methods and also non-invasive way. The image can show the entire pocket depth around teeth consistent and accurately without prodding the gums of the patient. The conventional method for dentists to assess gum health is to use an instrument called a periodontal probe which is a thin, hook-like metal tool that is marked like a tiny measuring stick and inserted in between the teeth and gums to see if the gums have shrunk back from the teeth, creating pockets. This method of measuring pocket depth is considered a … Read more
