背景：口内X光片有助于更准确地诊断牙周病。然而，必须考虑现代全景射线照片是否可以获得相当数量的信息。本研究的目的是确定侵袭性牙周炎或严重慢性牙周炎患者的可诊断骨质流失量在多大程度上取决于所使用的 X 射线技术类型。 方法：本研究共纳入 110 名受试者（63 名女性）。纳入标准为侵袭性牙周炎（N = 49）或严重慢性牙周炎（N = 61）的诊断。所有患者均可获得所有区域的全景X光片（全景）和口内胶片（8至10次单次曝光）。使用计算机辅助线性测量技术对全景片和口内片进行分析。根据牙槽嵴顶部 (AC) 和骨缺损底部 (BD) 的骨丢失量确定为牙根总长度的百分比。结果：根据检查的牙齿和参考点，47.01% 至 81.89% 的所有受试者表现出口内测量和全景测量之间的差异，总牙根长度的 10% 主要出现在上磨牙和前磨牙区域。在下颌骨中，在中切牙近中轮廓处观察到 BD 和 AC 的口内测量和全景测量之间的差异 > 总根长的 10%。结论：使用全景 X 线照片可以对预期骨丢失进行预定向。当骨水平发生快速变化时（例如侵袭性牙周炎），额外的口腔内胶片可能会有所帮助。
Background: Intraoral radiographs can aid in formulating a more accurate diagnosis of periodontal disease. However, it must be considered whether a comparable amount of information can be obtained with modern panoramic radiographs. The aim of this study was to determine to what degree the diagnosable amount of bone loss in patients with aggressive periodontitis or severe chronic periodontitis depends on the type of x-ray technique used.Methods: A total of 110 subjects (63 females) were included in this study. The inclusion criteria were the diagnosis of aggressive periodontitis (N = 49) or severe chronic periodontitis (N = 61). In all patients, panoramic radiographs (panoramic) and intraoral films of all regions (eight to 10 single exposures) were available. Analysis of the panoramic and intraoral films was carried out with a computer-assisted technique for linear measurement. The amount of bone loss in reference to the alveolar crest (AC) and bottom of the bony defect (BD) was determined as a percentage of total root length.Results: Depending on the examined tooth and reference point, 47.01% to 81.89% of all subjects showed differences between intraoral and panoramic measurements that were 10% of the total root length were found predominantly in the upper molar and premolar regions. In the mandible, differences between intraoral and panoramic measurements that were >10% of the total root length were observed for BD and AC at the mesial contour of the central incisor.Conclusions: A preorientation with respect to the expected bone loss is possible using panoramic radiographs. Additional intraoral films might be helpful where rapid changes of bone level are expected (e.g., aggressive periodontitis).
