Interventions
Patients were randomly allocated in a split-mouth study design to receive PRP injections on one side (PRP group) immediately before the start of protraction, while the other side received only saline
initially, the blood was centrifuged at 1600 rpm for 4 minutes to separate the plasma containing the platelets from the red cells. The plasma was drawn off the top and centrifuged for an additional 6
