The aim of this study was to determine the accuray of bleeding tendency measurements in order to assess the probability values of differences in number of bleeding sites at successive examinations in the individual patient. Duplicate bleeding tendency measurements were performed in patients who had received initial treatment. Measurements in deep and shallow pockets showed different reproducibility values. The proportion of agreement on lack of bleeding was relatively high (86%) in shallow‐pockets (≤4 mm) and decreased significantly in deep pockets (> 4 mm). The proportion of agreement on bleeding was relatively low (36%) in shallow pockets and increased significantly in deep pockets. Chance distributions were calculated on basis of the reproducibility values of bleeding and non‐bleeding on probing. It was found that only large differences in the number of bleeding sites between two examinations can indicate a possible change in the periodontal condition of the individual patient. The sensitivity of the individual mouth bleeding score can be increased by recording as many sites as possible.
