The purpose of this study was to establish a method for detection of the gingival inflammation by measuring the capacitance of the gingival fluid. Eight periodontally healthy students were selected for measuring the capacitance during development of the experimental gingivitis and eight patients with periodontal disease were selected for investigating the relationship between the degree of the disease and the capacitance. Before measuring, the gingival area was washed and dried carefully. The sensor was inserted in the periodontal pocket and measured the capacitance for ten sec. The correlation between the clinical findings and the capacitance of the gingival fluid was as follows. 1. Experimental gingivitis group 1) The capacitance of the gingival fluid tend to increase during the period. (p<0.01) 2) The significant correlation was found between the capacitance and Plaque Index, Gingival Index and Gingival Bleeding Index. (p<0.01) 2. Periodontal disease group 1) The significant correlation was found between the capacitance and Gingival Index and Gingival Bleeding Index. (p<0.01) 2) Less significant correlation was found between the capacitance and Plaque Index. (p<0.05) 3) Any significant correlation was not found between the capacitance and probing depth.
