To determine the relationship between gingival crevicular fluid flow and tooth mobility, 40 male patients with generalized chronic periodontitis and 10 male dental students with the good general and oral health were selected.
At initial examination, gingival crevicular fluid flow and tooth mobility on upper and lower anterior teeth were measured by Periotron(Harco Electronics, Canada) and Periotest (Siemens Co., Germany), respectively. And then probing depth and loss of attachment were sequentially measured.
The difference of gingival crevicular fluid flow and tooth mobility among 3 groups according to probing depth and loss of attachment was analyzed by unpaired t-test, and the correlations among gingival crevicular fluid flow, tooth mobility, probing depth and loss of attachment were analyzed by multiple r. gression of ABSTAT program.
The results were as follows:
1. Gingival crevicular fluid flow had a positive relationship with both probing depth (Y=10.0832X + 1.8114, p<0.001) and loss of attachment (Y=8.1075X + 4.0589, p<0. 001).
2. Tooth mobility had a positive relationship with both probing depth (Y =3.8496X + 1. 7117, p<0.001) and loss of attachment (Y =3.3821X + 1.3801, p<0.001).
3. There was a significant correlation between gingival crevicular fluid flow and tooth mobility. (Correlation coefficient: 0.5973, Y=1.4884X + 14.7544, p<0.001)
4. It was suggested that both gingival crevicular fluid flow and tooth mobility were affected by probing depth rather than loss of attachment.
