[The relationship between the amount of gingival crevicular fluid and periodontitis].

In this paper, we report the results of comparing the amount of GCF, collected from 100 patients suffering from periodontitis and 40 patients suffering from gingivitis with 64 normal control subjects. The results showed that the amount of GCF is independent of sex and where the GCF was collected, ie., either side of the maxillary or mandibular teeth. However, the fluid amount was closely related to inflammation of the periodontium and significantly related to the severity of inflammation and bone destruction. This study provide evidence that the determination of the GCF amount is an essential criteria for detecting periodontal activity.
