This study compares the evaluation of periodontal health using bone levels measured on periapical and bitewing radiographs with clinical parameters, such as periodontal screening and recording, gingival indexes, probing depths and attachment levels. The authors found that bitewing radiographs taken within six months of the clinical examination correlated better with the clinical data than older radiographs. However, they concluded that, overall, radiographs are not highly reflective of periodontal status. PSR scores, by contrast, showed significant associations with probing depths and attachment levels. The results support use of PSR as a screening tool for periodontal diseases.
本研究比较了利用根尖片和翼片上测量的骨水平评估牙周健康状况与临床参数，如牙周筛查与记录、牙龈指数、探诊深度和附着水平之间的差异。作者发现，在临床检查后六个月内拍摄的翼片与临床数据的相关性比旧的根尖片更好。然而，他们得出结论，总体而言，根尖片和翼片并不能很好地反映牙周状况。相比之下，PSR评分与探诊深度和附着水平显示出显著相关性。这些结果支持将PSR作为牙周疾病的筛查工具。
