Abstract：
Background/Objectives: Advancements in oral imaging technology are continually shaping the landscape of dental diagnosis and treatment planning. Among these, photon-counting computed tomography (PCCT), introduced in 2021, has emerged as a promising, high-quality oral technology. Dental imaging typically requires a resolution beyond the standard CT systems achievable with the specialized cone-beam CT. PCCT can offer up to 100 µm resolution, improve soft-tissue contrast, and provide faster scanning times, which are crucial for detailed dental diagnosis and treatment planning. Using semiconductor detectors, PCCT produces sharper images and can potentially reduce the number of scans required, thereby decreasing patient radiation exposure. This review aimed to explore the potential benefits of PCCT in dental imaging. Methods: This review analyzed the literature on PCCT in dental imaging from January 2010 to February 2024, sourced from PubMed, Scopus, and Web of Science databases, focusing on high-resolution, patient safety, and diagnostic efficiency in dental structure assessment. We included English-language articles, case studies, letters, observational studies, and randomized controlled trials while excluding duplicates and studies unrelated to PCCT\'s application in dental imaging. Results: Studies have highlighted the superiority of PCCT in reducing artifacts, which are often problematic, compared to conventional CBCT and traditional CT scans, due to metallic dental implants, particularly when used with virtual monoenergetic imaging and iterative metal artifact reduction, thereby improving implant imaging. This review acknowledges limitations, such as the potential for overlooking other advanced imaging technologies, a narrow study timeframe, the lack of real-world clinical application data in this field, and costs. Conclusions: PCCT represents a promising advancement in dental imaging, offering high-resolution visuals, enhanced contrast, and rapid scanning with reduced radiation exposure.
摘要：
背景/目标：口腔成像技术的进步正在不断塑造牙科诊断和治疗计划的格局。其中,光子计数计算机断层扫描（PCCT），在2021年推出，已经成为一个有希望的，高质量的口腔技术。牙科成像通常需要超过使用专用锥束CT可实现的标准CT系统的分辨率。PCCT可以提供高达100μm的分辨率，改善软组织对比度，并提供更快的扫描时间，这对于详细的牙科诊断和治疗计划至关重要。使用半导体探测器，PCCT可产生更清晰的图像，并有可能减少所需的扫描次数，从而减少患者的辐射暴露。本文旨在探讨PCCT在牙科成像中的潜在益处。方法:对2010年1月至2024年2月文献中PCCT在牙科影像学中的应用进行分析,Scopus,和WebofScience数据库,专注于高分辨率，患者安全,以及牙科结构评估中的诊断效率。我们包括英语文章，案例研究,信件,观察性研究，和随机对照试验，同时排除与PCCT在牙科成像中的应用无关的重复和研究。结果:研究突出了PCCT在减少伪影方面的优越性,这往往是有问题的，与传统的CBCT和传统的CT扫描相比，由于金属牙科植入物，特别是当与虚拟单能量成像和迭代金属伪影减少一起使用时，从而改善植入物成像。这篇评论承认局限性，例如忽视其他先进成像技术的潜力，一个狭窄的研究时间框架，缺乏该领域的实际临床应用数据，和成本。结论：PCCT代表了牙科影像学的一个有希望的进步，提供高分辨率的视觉效果，增强对比度,和快速扫描减少辐射暴露。
