Aim: To detect osteocalcin (OC) in gingival crevicular fluid (GCF) and to monitor the concentration of OC at what stage inflammation and bone resorption reaches their maximum following orthodontic activation. Materials and Methods: GCF samples were collected from six adult orthodontic patients (mean age = 22.3, range 20–24 years) on 3, 7, 10, 14, 21, 28, and 35 days after activation of orthodontic appliance, from the tooth surface where bone resorption was expected to occur. A total of 330 GCF sample were collected using filter paper strip, the volume measured by weighing. OC was analyzed using Enzyme-Linked immunoassay technique. Data were analyzed using the Statistical Package for Social Sciences software, SPSS (SPSS Inc., Chicago, IL, USA) version 15. Results: An increase in GCF volume and flow rate was noted in the 10th day after activation of the orthodontic appliance activation; however, due to high-standard deviation, the result was not significant. OC was detected in all GCF samples. The amount and concentration were quite variable. Increase in the amount of OC was observed between days 7 and 14. Conclusion: OC was detected in all samples. The quantity of OC increased at day 10 in a number of samples. There was no obvious association between OC concentration and time of collection.
