Overview
Brief Summary
The aim of this study was to evaluate the tooth movement with and without piezocision with regard to the levels of osteocalcin and cross-linked C-terminal telopeptides of type I collagen in the gingival crevicular fluid.
Detailed Description
15 systemically healthy subjects requiring extraction of the maxillary 1. premolars with distalization of the maxillary canines were enrolled to the study. Piezocisions were performed on the distal and mesial sides of the right maxillary canines while the left maxillary canines served as controls. Canine distalization was performed via closed-coil springs applying 150 g of force per side by using miniscrews as anchorage. Gingival crevicular fluid samples were collected from both mesial and distal sides of right and left maxillary canines at 0, 1, 7, 14 and 28 days. The gingival crevicular fluid levels of osteocalcin and cross-linked C-terminal telopeptides of type I collagen were determined by using ELISA. The rate of tooth movement was measured on 14 and 28 days.

Outcomes
Primary Outcomes
Gingival crevicular fluid osteocalcin level (ng/ml)
Time Frame: 28 days after canine distalization
Gingival crevicular fluid samples were collected from mesial and distal sides of the maxillary right and left canines.The gingival crevicular fluid level of osteocalcin was determined by using ELISA
Gingival crevicular fluid cross-linked C-terminal telopeptides of type I level (ng/ml)
Time Frame: 28 days after canine distalization
Gingival crevicular fluid samples were collected from mesial and distal sides of the maxillary right and left canines.The gingival crevicular fluid level of cross-linked C-terminal telopeptides of type I collagen was determined by using ELISA.
Secondary Outcomes
- The amount of canine movement (mm)(Baseline (day 0) before canine distalization and, 14 and 28 days after canine distalization)
- Retraction rate (mm/day) of canine movement(14 and 28 days after canine distalization)
