The present paper is a cross-sectional microradiographic study. Postmortem hemimandibles were radiographed with a microfocal high-resolution method. Microradiographic appearances of the feline periodontium are described and discussed. Mean relative alveolar bone support in clinically and histologically normal cats was 46.9%. Site-specific alveolar bone support (ABS) was calculated twice (blind). The 95% confidence limits of the method error for one observation were estimated. Differences between two site-specific measurements did not exceed +/- 2.72%. Microfocal radiography yielded valuable additional information about the feline periodontium and made it possible clearly to identify important dental and periodontal structures such as the CEJ (cementoenamel junction) and the bottom of infrabony defects.
本文是一项横断面显微放射学研究。对死后半侧下颌骨采用微焦点高分辨率方法进行射线照相。描述并讨论了猫牙周组织的显微放射学表现。临床和组织学正常的猫的平均相对牙槽骨支持率为46.9%。对特定部位的牙槽骨支持率（ABS）进行了两次（盲法）计算。估计了一次观察的方法误差的95%置信限。两次特定部位测量之间的差异不超过±2.72%。微焦点射线照相术提供了有关猫牙周组织的有价值的额外信息，并使得清晰识别重要的牙齿和牙周结构（如牙骨质釉质界（CEJ）和骨下袋底部）成为可能。
