In order to analyze the possible relationship between the quantity of gingival crevicular fluid (GCF) and clinical periodontal status, the severity of gingival inflammation (gingival index (GI) scores) and probing depth (PD) were recorded and GCF samples were obtained from 1111 sites. These sites were further analyzed on the basis of distinct tooth groups to evaluate the significance of particular anatomical sampling locations. Statistical analysis of cumulative data showed significant increases in GCF volume with greater GI scores and PD. Correlations between GCF volume and both of the clinical measures were also strongly positive and significant for all sites. However, significant differences in GCF volume were observed between the anterior and posterior sampling sites. Increases in volume with increasing GI and PD were more marked for incisor and canine teeth. Similarly, the relationship between the quantity of GCF and clinical periodontal status was more clear and absolute in the anterior region than in the premolar and molar areas. These findings suggest that the quantity of GCF is not constant throughout the entire dentition, and that the relationship between GCF measurements and clinical periodontal status is site-based. This unique feature of GCF seems to be an essential factor in the design of GCF-related studies. (J. Oral Sci. 42, 231-238, 2000)
