The purpose of this study is to estimate the capacity of the gingival bleeding index (B.I.) to assess the inflammatory condition of the periodontium. Thirteen periodontally healthy students (mean age: 24.1) participated in this study. Prior to the start of the experimental period, a thorough scaling was performed on each subject and a correct brushing technique (mostly scrubbing method) was instructed. After a healthy oral condition, free from the plaque, was established, the subject was asked to refrain from brushing. Items observed were bleeding index, plaque index, crevicular depth and the amount of the gingival crevicular fluid. Care was taken to observe any change of the gingival color. Photographic records were also made on every appointment. The results were as follows: 1. A significant correlation was observed between the bleeding index and the amount of the gingival crevicular fluid. 2. The plaque index and the amount of the gingival crevicular fluid were also highly correlated. 3. Increase of the crevicular depth was observed after the cessation of the plaque control. 4. The depth of the mesial and distal sulcus were deeper than those of labial and lingual sulcus. 5. The bleeding index measured at the mesial and distal sulcus was higher than the one at the labial and lingual sulcus. It is concluded that the gingival bleeding index is a substantial clue for obtaining the information about the inflammatory condition of the gingiva.
