Orthodontic Tooth Movement Clinical Trial
Official title:
Impact of Gingival Crevicular Fluid microRNAs on Orthodontic Tooth Movement: a Split Mouth Study
A split-mouth study is conducted in order to evaluate the impact of orthodontic movement on the expression of gingival crevicular fluid miRNAs related to inflammation and osteoclastogenesis during canine distalization following asymmetrical extraction treatment of upper first premolars. Samples of gingival crevicular fluid on the mesial and distal side of the canines to be examined will be performed during the baseline and during various follow-ups.
A split-mouth study is conducted in order to evaluate the impact of orthodontic movement on the expression of gingival crevicular fluid miRNAs related to inflammation and osteoclastogenesis during canine distalization following asymmetrical extraction treatment of upper first premolars. Orthodontic tooth movement induces bone remodeling by various signaling pathways. The variations in miRNAs expression and their impact in inflammation and osteoclastogenesis during the various stages of orthodontic tooth movements is not fully understood. 58 patients requiring asymmetrical upper first premolar extraction for orthodontic purposes have been enrolled for this split-mouth study: the canines to be distalized on the extractive site are considered as the test group, the controlateral canines (on the side without first premolar extraction) areconsidered as normal controls. ;
