Photoacoustic imaging for monitoring Periodontitis

23 January 2022 • 9:00 AM - 9:15 AM PST | Room 211 (Level 2 South)


Periodontitis is a big public health problem. Its primary feature is the clinical attachment loss (CAL), which can be qualified by measuring the pocket depth by using a periodontal probe. In this work, we use photoacoustic tomography as an alternative tool to qualify the pocket depth. We measured the pocket depth of 40 swine teeth by using the William periodontal probe and photoacoustic imaging. The two groups of measurements are highly correlated. We also imaged the pocket areaof human first molars. Our studies proved that photoacoustic imaging can be used as a clinical tool to measure the pocket depth.
