In this study, we investigated both inter-examiner and intra-examiner differences in the evaluation of the marginal fracture characteristics of dental amalgam restorations. Evaluations were made by matching intra-oral photographs of the occlusal surfaces of clinical restorations to a reference set of clinical photographs illustrating increasing amounts of marginal fracture. Four amalgam alloys and five examiners provided the data base. Differences in marginal fracture indices were found among examiners and between evaluation times for the same examiners. However, these differences were reduced significantly after application of a standardization procedure.
在本研究中，我们调查了在评估银汞合金修复体边缘骨折特征时检查者之间以及同一检查者内部的差异。通过将临床修复体咬合面的口内照片与一组说明边缘骨折程度逐渐增加的临床参考照片进行匹配来进行评估。四种银汞合金和五名检查者提供了数据库。发现检查者之间以及同一检查者在不同评估时间之间边缘骨折指数存在差异。然而，应用标准化程序后，这些差异显著减小。
