“…We were motivated to use this commercially available transducer because of its relatively high bandwidth (7 to 15 MHz) and angled design suitable for imaging the posterior of the mouth. 30 , 31 Although designed for superficial applications such as intraoperative neural imaging and musculoskeletal imaging, 32 the hockey-stick design is also suitable for imaging the molars (up to the first molar in human subjects). Our work here integrated optical fibers for both photoacoustic and ultrasound imaging.…”

Periodontitis is a public issue and imaging periodontal pocket is important to evaluate periodontitis. Regular linear transducers have limitations in imaging the posterior teeth due to their geometry restrictions. Here we characterized a transducer that can image the entire human mouth including assessment of periodontal pockets via a combination of photoacoustic and ultrasound imaging. Unlike conventional transducer design, this device has a toothbrush-shaped form factor with a side-view transducer to image molars (total size: 1 x 1.9 cm). A laser diode was integrated as the light source to reduce the cost and size and facilitates clinical transition. The in vivo imaging of a molar of a periodontal patient demonstrated that the transducer could image in the posterior area of gum in vivo; the value determined by imaging was within 7% of the value measured clinically.
