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.

使用旋转传感器进行口内超声成像并通过机器学习识别牙周特征

创新的口腔内超声设备具有基于智能人工智能的牙齿解剖学识别功能，可以为口腔健康诊断和治疗提供重要信息，并为发育性牙科的实时检测提供线索。然而，最大的挑战是，当前的超声波技术由于体积大且频率低而只能用于外部使用。我们报告了一种紧凑型多功能超声口腔内设备，该设备由一个旋转探头组成，该探头围绕手持式便携式手柄牢固枢转，可使用高频超声检查（高达 25 MHz）对口腔内解剖结构进行实时成像。口内超声设备可通过旋转头部调整成像平面的各种方向，提供口腔内结构的实时、高分辨率超声图，包括大多数牙齿类型的牙周组织和上颌腭。集成基于机器学习的算法，可自动识别重要结构，包括牙槽骨和牙骨质-牙釉质连接处。具有人工智能的智能口腔内超声设备可以创新口腔健康诊断和治疗计划，实现精准健康和患者护理。
