Innovative intraoral ultrasound devices with smart artificial intelligence-based identification for dento-anatomy could provide crucial information for oral health diagnosis and treatment and shed light on real-time detection of developmental dentistry. However, the grand challenge is that the current ultrasound technologies are meant for external use due to their bulkiness and low frequency. We report a compact versatile ultrasound intraoral device that consists of a rotational probe head robustly pivoted around a hand-held and portable handle for real-time imaging of intraoral anatomy using high-frequency ultrasonography (up to 25 MHz). The intraoral ultrasound device that could be adjusted for various orientations of the imaging planes by rotating the head provides real-time, high-resolution ultrasonograms of intraoral structures, including dento-periodontium of most tooth types and maxillary palate. Machine learning-based algorithms are integrated to automate the identification of important structures, including alveolar bone and cementum-enamel junction. The intraoral ultrasound device smartened with artificial intelligence could innovate oral health diagnosis and treatment plans toward precision health and patient care.
具有基于智能人工智能的 dento-anatomy 识别功能的创新口腔内超声设备可为口腔健康诊断和治疗提供关键信息，并为发育牙科学的实时检测提供线索。然而，巨大的挑战在于，由于其体积大和低频，当前的超声技术仅适用于外部使用。我们报告了一种紧凑的多功能口腔内超声设备，该设备由旋转探头头组成，该探头头通过坚固的枢轴围绕手持式和便携式手柄旋转，以使用高频超声（高达 25 MHz）实时成像口腔内解剖结构。可以通过旋转头部来调整探头头的各种成像平面方向的口腔内超声设备可提供包括大多数牙齿类型的 dento-periodontium 和上颌腭在内的口腔内结构的实时高分辨率超声图像。已集成基于机器学习的算法来自动识别重要结构，包括牙槽骨和牙骨质-牙釉质交界处。人工智能智能化的口腔内超声设备可以革新口腔健康诊断和治疗计划，实现精准健康和患者护理。
