Intraoral radiographs are widely used in periodontal diagnosis and research. However, accurate radiographic interpretation is only possible with high quality images. Some of the technical and geometric variables to consider have been presented. Early periodontal lesions are not detected in radiographs. The amount of periodontal destruction in more advanced disease is generally underestimated. The accurate topography of periodontal pockets and the buccal and lingual aspects of the teeth cannot be visualized. Clinical probing is therefore a prerequisite for a complete periodontal diagnosis. However, radiographs are a valuable adjunct for the periodontal diagnosis and the diagnosis of trauma from occlusion. With standardized systems, radiographs may furnish additional quantitative data in clinical research.
口内X光片在牙周病诊断和研究中被广泛应用。然而，只有高质量的图像才能进行准确的X光片解读。文中已介绍了一些需要考虑的技术和几何变量。早期牙周病变在X光片中无法检测到。在更晚期的疾病中，牙周破坏的程度通常被低估。牙周袋的准确形态以及牙齿的颊侧和舌侧情况无法通过X光片显示。因此，临床探诊是完整牙周病诊断的前提条件。然而，X光片对于牙周病诊断和咬合创伤诊断是有价值的辅助手段。使用标准化系统时，X光片可为临床研究提供额外的定量数据。
