“…By localizing these biomedical landmarks in ultrasonography, diagnosing and monitoring oral heath can be achieved in a fast, low-cost and non-invasive manner. Compared with the most recent work (13) that accessed 18 human teeth, SS-19-128 has 55.6% better range of access. The system was flexible and showed utility across a small cohort of five subjects.…”

“…Six anatomical features were determined: I – tooth surface; II – gingiva; III – GM; IV – CEJ; V – AB; VI – ABC. ( e ) Comparison of accessible imaging range between our prior work (13) and SS-19-128 with size miniaturization. Accessible teeth were marked as yellow.…”

“…Although the axial resolution of SS-19-128 was relatively lower, it was sufficient for periodontal imaging because features sizes are on the millimeter scale (e.g., median gingival thickness =1.1 mm). (41) The axial and lateral resolution of the Philips CL15-7 (9 MHz) (13) was 210 μm and 196 μm, respectively. The axial resolution of CL15-7 was 106% lower than SS-19-128 because of its lower center frequency.…”

“…(7) Compared with laser Doppler flowmetry, Doppler ultrasound measurement offers real-time diagnosis as well as high reproducibility that allows monitoring oral microcirculation changes over time; metal constructions and/or implants do not limit studies of blood flow in the gingiva or tooth pulp. (8) Previously, we and others (9)(10)(11)(12)(13)(14) have reported that ultrasound imaging has major value in oral health and can improve the limitations of conventional methods. (15,16) Ultrasound offers visualization of anatomical features including the alveolar bone (AB), alveolar bone crest (ABC), cementoenamel junction (CEJ), gingival margin (GM), gingival thickness, etc.…”

Periodontitis affects nearly 50% of Americans. Conventional clinical assessment based on periodontal probing remains the gold standard despite being operator-dependent, time-consuming, and often painful. In contrast, ultrasound imaging is non-invasive, portable, low-cost, and free of ionizing radiation. Unfortunately, most conventional ultrasound transducers can only access anterior teeth due to the size of the imaging equipment. Here, we characterized a novel and customized periodontal ultrasound transducer SS-19-128 that can examine the entire human mouth. The transducer is 1.8 cm width by 1 cm height, including 128 channels with a center frequency of 19 MHz. The axial and lateral spatial resolution at 5.5 mm depth is 102.1 μm and 142.9 μm, respectively. The penetration depth in tissue mimicking phantom is over 31 mm. Imaging was performed on 3 human subjects, and statistical analysis on swine jaws indicated a high agreement with the gold standard.
