Reliability of partial-mouth periodontal examinations for diagnosing periodontal disease _x000D_
<br>Purpose: The aim of this study was to evaluate the diagnostic reliability of different partial-mouth periodontal examinations (PMPEs) on periodontal disease including their accuracy on 1) detection of periodontitis, 2) staging of periodontal disease and 3) mean clinical parameters. _x000D_
<br>Methods: All patients were diagnosed according to 8 different types : (A) full-mouth, (B) Community periodontal index treatment needs (CPITN) codes, (C) panoramic radiographs only, (D) clinical parameters only, (E) 6 teeth including first molar (#11,#16,#26,#31,#36,#46), (F) CPITN index teeth (#11,#16,#17,#26,#27,#31,#36,#37,#46,#47), (G) Ramfjord teeth (#16,#21,#24,#36,#41,#44), and (H) 10 teeth including Ramfjord teeth (#14,#16,#21,#24,#26, #34,#36,#41,#44,#46). For case definition, 2018 World Workshop EFP/AAP consensus was used for all types except for ‘type B’. The accuracy of diagnosis was assessed by Kappa coefficient value and the sensitivity, specificity of diagnosis was evaluated using Area Under the Curve/ Receiver Operating Characteristics (AUC/ROC) value. For mean value of clinical parameter, intraclass correlation coefficient (ICC) was analyzed by each type. _x000D_
<br>Results: Total of 218 patients (130 female, 88 male) were included in this study. Considering general accuracy, sensitivity and specificity, type F showed statistically significant results in both presence of periodontitis and determining its staging. For clinical parameters, type H presented highest correlation with reference group in all clinical indices including mean plaque index (ICC=0.98), mean pocket depth (ICC=0.97), mean mSBI (ICC=0.98), mean gingival index (ICC=0.96), mean CAL (ICC=0.96) and mean BOP% (ICC=0.97). _x000D_
<br>Conclusions: Specific types of PMPEs showed reliability and efficacy in diagnosing periodontitis and various clinical parameters, suggesting their potential use in clinical practice to save chair time and lower patients’ discomfort compared to FMPE. _x000D_
