Aim:
To evaluate the levels of leptin in gingival crevicular fluid (GCF) during orthodontic tooth movement and to find the role of leptin as a mediator for tooth movement.
Materials And Methods:
GCF was collected from 25 subjects and the levels of leptin in it were measured. Sample (A) pretreatment, (B) 6 h after applying retractive orthodontic force from right side canine, (C) without retractive force from left side canine, and after 21 days from right canine (D), and left canine (E).
Results:
GCF Leptin concentration in pretreatment, 6 h control and 21st day control were all similar. GCF leptin concentration at 6 h test tooth site was increased which was statistically significant. GCF leptin concentration in 21st day test tooth was decreased only a little than the control tooth which shows statistically no difference.
Conclusion:
Leptin is one of the mediators of orthodontic tooth movement.
