Although the gingival index and sulcus bleeding index have been widely used as indicators of periodontal status, there is some disagreement among investigators as to their meaning and significance. A clinical study was undertaken to monitor the occurrence of gingival bleeding, oedema, and change in colour in subjects with and without periodontal disease, and it was found that the combinations of these clinical symptoms often did not correspond exactly with an index score. It is therefore suggested that any study of periodontal disease should be based on fundamental criteria, such as bleeding or oedema, rather than on composite indices.
尽管牙龈指数和龈沟出血指数已被广泛用作牙周状况的指标，但研究人员对于它们的含义和意义仍存在一些分歧。一项临床研究旨在监测患有和未患有牙周疾病的受试者牙龈出血、水肿及颜色变化的发生情况，结果发现这些临床症状的组合往往与指数评分并不完全相符。因此，建议任何牙周疾病研究都应基于出血或水肿等基本标准，而非复合指数。
