Localization of cementoenamel junction in intraoral ultrasonographs with machine learning

Photoacoustic imaging of posterior periodontal pocket using a commercial hockey-stick transducer

“…16 , 17 Ultrasound imaging has been used for dental implant studies, 18 , 19 and high-resolution ultrasound imaging can help identify the gingival sulcus, GM, alveolar bone, alveolar bone crest, and the cementoenamel junction. 20 – 22 One subset of ultrasound is photoacoustic imaging, which creates images via the ultrasound created by incident light pulses. 23 , 24 We previously showed that photoacoustic-ultrasound imaging can measure the periodontal pocket with a food grade contrast agent (cuttlefish ink) in swine and humans with good correlation to standard probing.…”

A hybrid mask RCNN-based tool to localize dental cavities from real-time mixed photographic images

“…The panoramic radiographs may cause mistreatment due to misdiagnosis in some instances ( Endres et al, 2020 ). Utilizing ultrasound images to local dental cavities via deep learning approaches requires vast expertise in scanning and ultra-sound operations ( Nguyen et al, 2021 ). Bitewing radiographs show less sensitivity for a variety of services, including proximal and occlusal.…”

Posterior photoacoustic/ultrasound imaging of the periodontal pocket with a compact intraoral transducer

“…Although there are clinical and small transducers e.g. , endoscopic transducers that could be potentially adapted for periodontal imaging [8] , they usually have low central frequency at around 5 MHz, which is insufficient to resolve small structures of tooth [9] , [10] . For this reason, it is important to develop a photoacoustic/ultrasound transducer that can image posterior teeth with high resolution.…”
