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
