Clinical trials: Space Closure, Orthodontic, open to volunteers
Gingival Cleft, Orthodontic Space Closure
Gingival Cleft Development at Two Time Points of Canine Retraction
The goal of this split-mouth randomized controlled trial is to assess whether the timing of extraction space closure-early vs. delayed initiation-affects the incidence of gingival cleft development in orthodontic patients.

Tooth Crowding
Effect of Force Magnitude on Canine Retraction and Gingival Crevicular Fluid Proteome
This study aims to examine the effect of force levels in orthodontic treatment during canine retraction. Force levels refer to the pressure applied by the orthodontic devices to move teeth.
