To determine the changes of gingival crevicular fluid flow and tooth mobility following surgical periodontal treatment, 47 patients(27 men and 20 women: 28 to 52 years old) with generalized chronic periodontitis were selected.
Gingival crevicular fluid flow was by Periotron® (Harco Electronics, Canada), and tooth mobility was checked by Periotest®(Siemens, Germany) at the initial examination, 1 week-after scaling, 1, 2, 4, 6, 8, and 12 weeks following modified Widman flap oPeration.
The changes of gingival crevicular fluid flow and tooth mobility according to healing process was statistically analyzed by paired t-test.
The results were as follows:
1. At 1 week-after scaling, gingival crevicular fluid flow-was decreased(p<0.05) but tooth mobility was increased (p<0.05).
2. Gingival crevicular fluid flow was gradually decreased according to healing process following surgical periodontal treatment (p<0.05), and from 6 week-after surgery it was reduced to stable level.
3. Tooth mobility showed maximum level at 2 week-after surgery (p<0.05), and thereafter it was decreased gradually until that at 12 week- after surgery was lower than baseline T level(p<0.05).
4. There was a correlation between gingival crevicular fluid and tooth mobility following surgical periodontal treatment with each period(p<0.05).
