Periodontal disease is an inflammatory condition that can reach the periodontal protection, gingival and support, alveolar bone, cementum and periodontal ligament. Early diagnosis is important to prevent periodontal disease. Periodontal Screening and Recording (PSR) have been used in this study to evaluate the presence of periodontal disease at Planning Clinic of the Federal University of Fluminense, Nova Friburgo, RJ, Brazil. Periodontal examinations were performed on 200 patients using OMS probe -621 approved by American Dental Association (ADA). The results show that sextants 1 and 3 had higher prevalence of code 3, probing depth ranging from 3.5 to 5.5 mm, bleeding on probe, followed by edentulous sextants. Sextants 2, 4, 5 and 6 had code 2, presence or absence of bleeding on probe, calculus and/or excesses of the margins restorations. The asterisk code represented 44.5% of all sextants evaluated. This study demonstrates a higher diagnosis of periodontitis, due to the criteria of PSR that diagnosis is based on the worst code of all sextants. The analysis of data reveals that alveolar bone loss was the most frequent in this study population. PSR index was effective for the diagnosis of periodontal conditions of adults' population from Nova Friburgo, RJ, Brazil.
