背景：传统的二维（2-D）X线照片的局限性已在许多研究中得到强调。因为图像是三维（3-D）牙齿和牙周组织的2-D图，所以这些结构可以彼此叠加。最近，3-D图像分析的计算机断层扫描（CT）被引入到牙科，但它已经很少被使用在牙周field.Methods：本病例报告的目的是介绍一种新开发的，紧凑的计算机断层扫描系统的临床应用，用于评估再生治疗的结果在成人牙周炎患者（男性，年龄55岁）。为了评估骨缺损，包括分叉病变，我们对19号牙齿进行了口内X线片和CT扫描。我们在手术时记录了许多临床参数。我们比较了骨缺损的CT图像和传统的X线片获得的图像与真正的骨缺损的形态在手术location.Results：一年后，牙周手术，我们再次采取CT扫描和传统的X线片，和新的图像的骨缺损进行了比较和评价。对新的CT图像进行三维重建，并与术前进行比较。CT提供了3-D图像的质量优良的牙周骨缺损和分叉involvement.Conclusions的形态评价：我们认为，CT是一个有用的辅助牙周检查和诊断，并在预测和评价牙周治疗的结果。
Background: The limitations of conventional 2-dimensional (2-D) radiographs have been emphasized in many studies. Because the image is a 2-D map of the 3-dimensional (3-D) tooth and periodontal tissue, these structures may be superimposed on each other. Recently, 3-D image analysis by computed tomography (CT) was introduced to dentistry, but it has been used only rarely in the periodontal field.Methods: The purpose of this case report was to introduce the clinical application of a newly developed, compact computed tomography system for evaluating the outcome of regenerative therapy in an adult patient with periodontitis (male, aged 55 years). To evaluate the bone defects including furcation involvement, we took an intraoral radiograph and performed CT scanning on tooth #19. We recorded a number of clinical parameters at the time of surgery. We compared the images of the bone defect obtained by CT images and the conventional radiograph with the true bone defect morphology at the surgical site.Results: One year after the periodontal surgery, we again took CT scans and a conventional radiograph, and the new images of the bone defect were compared and evaluated. The new CT images were reconstructed for 3-D evaluation and compared with those taken before surgery. The CT provides 3-D images of excellent quality for evaluating the morphology of the periodontal bone defect and furcation involvement.Conclusions: We consider that CT is a useful aid in periodontal examination and diagnosis, and in the prediction and evaluation of periodontal treatment outcomes.
