Aim To investigate the agreement between the 2018 EFP/AAP periodontitis case classification and the 2012 CDC/AAP criteria. Materials and Methods This cross‐sectional study assessed a population‐based sample from a rural area in southern Brazil. A complete periodontal examination was performed at six sites/tooth. The periodontitis case definition was estimated and compared according to the 2018 EFP/AAP classification and the 2012 CDC/AAP criteria (reference). Diagnostic tests included sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and area under ROC curve (AUC). Results Five hundred and eighty‐eight subjects with ≥6 teeth each were included. Based on the 2018 EFP/AAP classification, 71.1% of the subjects were classified as stage III/IV showing 100% agreement with 2012 CDC/AAP criteria for the severe category. For the moderate and severe classification, the 2018 EFP/AAP SN was 99.8% and 100%, SP 13.6% and 43.6%, PPV 83.4% and 47.4%, and NPV 93.7% and 100%, respectively. The AUC was 0.9059 (95% CI = 0.879–0.933) and the optimal cut‐off based on the curve was stage III. Conclusions The 2018 EFP/AAP periodontitis case classification showed high agreement with the 2012 CDC/AAP criteria in a rural sample with high periodontitis occurrence.

Background: Factors related to head and neck cancer and the treatment of the disease can affect quality of life. The aim of this study was to determine factors associated with the severity of impact on oral health-related quality of life (OHRQoL) in survivors of head and neck cancer using a multivariate analysis. Methods: This cross-sectional study evaluated 90 volunteers who had completed radiotherapy at least 3 months earlier. OHRQoL was assessed using oral health impact profile (OHIP-14) and the data were analyzed using robust variance poisson regression models. Results: The mean total OHIP-14 score was 23.98 ± 12.55. Patients with hyposalivation had 56% higher (worse) mean OHIP-14 total scores (CI:1.11-2.18) and patients with advanced stage tumors had 31% higher mean OHIP-14 total scores (CI:1.03-1.66) in multivariate analyses.Conclusion: OHRQoL of survivors of head and neck cancer experienced a negative impact following radiotherapy. The impact was associated with hyposalivation and advanced stage tumors. K E Y W O R D Shead and neck neoplasms, radiotherapy, quality of life, xerostomia, oral health
