title: Screening for periodontal disease: radiographs vs. PSR.
abstract: 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.
