This work compared the assessment of clinically relevant parameters by two-dimensional, that is, full-mouth intraoral radiograph (I-O) and panoramic radiograph (OPT), and three-dimensional, that is, cone beam computed tomography (CBCT), imaging methods. Different radiographic images (CBCT, I-O and OPT) were available for a 53-year-old female patient with dental and periodontal problems. A total of 14 dental and periodontal parameters were assessed by two independent examiners and compared among the three radiographic imaging modalities. For 10 parameters (71%), the CBCT images were superior to both I-O and OPT images. In contrast, CBCT demonstrated an inferior performance compared to I-O and OPT in the assessment of caries and dental restorations. Compared to OPT, I-O provided more clinically relevant findings for 10 out of 14 parameters (71%). Agreement between I-O and OPT was found with respect to dehiscence, fenestration, the number of bone walls and the root canal cross-section. Differences between the radiographic images were more likely to be detected when maxillary teeth rather than mandibular teeth were assessed with regard to furcation involvement, root proximity and root fusion.
这项研究比较了二维成像方法，即全口口腔内X光片（I-O）和全景X光片（OPT），以及三维成像方法，即锥形束计算机断层扫描（CBCT），对临床相关参数的评估。对于一名患有牙齿和牙周问题的53岁女性患者，可获得不同的X光影像（CBCT、I-O和OPT）。两名独立检查人员对总共14项牙齿和牙周参数进行了评估，并在三种X光成像方式之间进行了比较。对于10项参数（71%），CBCT影像优于I-O和OPT影像。相比之下，在龋齿和牙齿修复体的评估中，CBCT表现不如I-O和OPT。与OPT相比，I-O在14项参数中的10项（71%）上提供了更多临床相关结果。在牙龈开裂、开窗、骨壁数量和根管横截面方面，发现I-O和OPT之间具有一致性。在上颌牙齿而非下颌牙齿的根分叉病变、牙根邻近度和牙根融合评估中，更有可能检测到X光影像之间的差异。
