Autorrelato de higiene oral e sinais de doença periodontal para o diagnóstico de periodontite severa

Abstract

The objective of this study was to evaluate the performance of self-report questions related to oral hygiene and to the periodontal condition to estimate the occurrence of severe periodontitis. Records of individuals diagnosed with severe periodontitis or gingivitis were included in the study. The periodontal condition was determined by the periodontal screening recording exam (PSR). Severe periodontitis were patients identified with PSR code 4 and healthy/gingivitis codes 0, 1 or 2. Self-report of conditions related to signs and symptoms of periodontal diseases, gingival bleeding (OS) and dental mobility (MOB) frequency of brushing (EF), interdental cleaning (ID) and oral antiseptic use (AO) were evaluated for the ability to predict the diagnosis of severe periodontitis when compared to patients with gingivitis. A total of 267 patients' charts were included, 80 of them with severe periodontitis (29.9%). Results: This group had a statistically significant (p <0.05) mean age (40 ± 12.1 x 34.2 ± 12.7 years), a higher proportion of men (47.5% vs. 29,9%) and lower AO (27.8% x 45.1%). On the other hand, a higher proportion of SG (61% x 32.6%) and MOB (17% x 4.3%). No differences were found for MOB, FE and ID. Logistic regression including the statistically significant variables besides age and sex generated values of SS = 31.1%, SP = 95.3% and receiver operating characteristic (ROC) = 75.4%. Self-report measures related to periodontal condition present moderate predictability to identify patients who do not present severe periodontitis.
