In epidemiology and clinical research, the reproducibility of clinical parameters is most important. In this study, we examined the inter-and intra-examiner reliability of each of the following clinical parameters : plaque index (PID, gingival index (GI) , probing depth (PD), attachment level (AL), and bleeding on probing (BOP). PD, AL, and BOP measurements were carried out with an electronic probe, The Florida Probe^<[O!R]>. The measurements were performed on 17 subjects (5 patients and 12 healthy subjects). Clinical parameters were measured twice in each subject at intervals of 1-2 hours. For inter-examiner reliability, the first measurement was performed by one examiner and the second measurement by another examiner. For intra-examiner reliability, each measurement was performed on all subjects by one examiner. Inter-examiner reliability of clinical parameters were 0.52 (PII), 0.52 (GI) , 0.59 (BOP) (PII, GI, BOP : Kraemer's Kappa), 0.73 (PD), 0.56 (AL) (PD, AL : correlation coefficient). Intra-examiner reliability of clinical parameters were O.71 (PII), O.66 (GI), O.52 (BOP) (PII, GI, BOP : Kraemer's Kappa), 0.97 (PD), 0.94 (AL) (PD, AL : correlation coefficient) . The results indicate that clinical parameters (PII, GI, PD, AL, BOP) can demonstrate good inter-and intra-examiner reliability. J. Jpn. Soc. Periodontol., 41 : 144-152, 1999.
