背景和技术需要一种更安全的替代放射成像的方法。我们提出了一种用于牙科成像的多光谱近红外扫描光纤内窥镜（nirSFE），该内窥镜被设计为具有近红外（NIR）成像（1200-2000 nm）的最小成像探头。Materials and MethodsThe prototype nirSFE被设计用于在1310，1460或1550 nm处扫描激光照明的宽视场前向观察。不同大小和位置的人工病变制备的近端表面上提取的人类牙齿，以检查这种新的牙科成像模式的能力和局限性。十九个人工邻间病变和几个自然的咬合病变提取的牙齿成像与nirSFE，OCT，和microCT.ResultsOur nirSFE系统有一个灵活的轴，以及探针尖端直径为1.6毫米和9毫米的刚性长度。小巧的外形和多光谱NIR成像功能可实现多个视角，并可靠地检测可能延伸到牙本质的病变。在19个人工邻间病变中，在1460 nm扫描照明下工作的nirSFE反射成像和在1310 nm扫描照明下工作的OCT对更接近咬合面的邻间病变表现出高灵敏度。通过查看真实的实时咬合侧nirSFE视频，来自非盲培训用户的诊断表明真阳性率为78.9%。There were no false positives.ConclusionsThis study demonstrates，nirSFE may be used for detecting occlusive lesions and interproximal lesions located less than 4 mm under the occlusive surface.该成像系统的主要优点包括灵活性和小外形尺寸带来的多视角，以及捕获真实的实时视频的能力。多光谱nirSFE有可能用作低成本牙科相机，用于在不暴露于电离辐射的情况下检测牙齿病变。激光外科医学51：459-465，2019。© 2019 Wiley Periodicals，Inc.
Background and ObjectiveA safer alternative method to radiographic imaging is needed. We present a multispectral near‐infrared scanning fiber endoscope (nirSFE) for dental imaging which is designed to be the smallest imaging probe with near‐infrared (NIR) imaging (1200–2000 nm).Materials and MethodsThe prototype nirSFE is designed for wide‐field forward viewing of scanned laser illumination at 1310, 1460, or 1550 nm. Artificial lesions with varying sizes and locations were prepared on proximal surfaces of extracted human teeth to examine capability and limitation of this new dental imaging modality. Nineteen artificial interproximal lesions and several natural occlusal lesions on extracted teeth were imaged with nirSFE, OCT, and microCT.ResultsOur nirSFE system has a flexible shaft as well as a probe tip with diameter of 1.6 mm and a rigid length of 9 mm. The small form factor and multispectral NIR imaging capability enables multiple viewing angles and reliable detection of lesions that can extend into the dentin. Among nineteen artificial interproximal lesions, the nirSFE reflectance imaging operating at 1460‐nm and OCT operating at 1310‐nm scanned illumination exhibited high sensitivity for interproximal lesions that were closer to occlusal surface. Diagnosis from a non‐blinded trained user by looking at real‐time occlusal‐side nirSFE videos indicate true positive rate of 78.9%. There were no false positives.ConclusionsThis study demonstrates that nirSFE may be used for detecting occlusal lesions and interproximal lesions located less than 4 mm under the occlusal surface. Major advantages of this imaging system include multiple viewing angles due to flexibility and small form factor, as well as the ability to capture real‐time video. The multispectral nirSFE has the potential to be employed as a low‐cost dental camera for detecting dental lesions without exposure to ionizing radiation. Lasers Surg.
