Sixty subjects (42 subjects with dentures and 18 subjects without dentures) were participated in this study. Crevicular fluid flow (Periotron unit: GCF), gingival index (GI), plaque index (PH) and probing depth (PD) of 209 marginal gingiva around natural and crowned abutment teeth were measured to evaluate gingival condition.
The following results were obtained.
1. The GI, PII and PD in subjects with dentures were higher than those in subjects without dentures. The GCF in subjects with dentures was inclined to be high comparing with those in subjects without dentures.
2. The GCF, GI and PD of crowned teeth in the subjects with dentures were higher than those of natural teeth. On the other hand, the GCF, GI and PD of crowned teeth in the subjects without dentures were almost equal to those of natural teeth.
3. The coefficient of correlation between GCF and other indices (GI, PII, PD) were+0.66 (p<0.01), +0.38 (p<0.01) and+0.38 (p<0.01), respectively.
