Variation in Rate of Orthodontic Tooth Movement in Response to Platelet Rich Plasma Therapy

Study Overview
=================
Brief Summary
-----------------
PRP from 5 ml blood was prepared and 60 units were injected into the buccal vestibule of patient before initiating canine retraction using NiTi coil spring. Pre and post cervical, incisal and mid distances were measured using Vernier calliper.

Detailed Description
-----------------
Platelet rich plasma was prepared using patients own blood. The production of PRP began with a 6-mL homologous blood sample that was withdrawn from the donor via venupuncture. One milliliter of the blood sample was set apart to determine the concentration of platelets and leukocytes in whole blood. The remaining 5 mL was mixed with an anticoagulant (3.8%, 1-mL sodium citrate) to prevent clotting. The blood sample was centrifuged at 113 g for 5 minutes to separate the plasma containing the platelets from the red cells. The plasma was drawn off the top and centrifuged for an additional 2 minutes at 3772 g to separate the platelets. Suitable platelet concentrations were achieved by the resuspension of PRP with plasma (high platelet concentration, 5 times the concentration in whole blood).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: PRP group<br>patients in which 60 units of prp was injected | Biological: platelet rich plasma<br>* Platelet rich plasma was prepared using patients own blood. 60 units of PRP was injected on one side of the arch using insulin syringe. Each patient served as his/her own control (the side with PRP injected) and experimental group (the side without PRP injected). Whether the right or left side served as control or experimental was determined by lottery method. Patients were recalled after 4 weeks and the measurements were repeated again between lateral incisors and canines at mid, cervical and incisal of the teeth and their mean was recorded.<br>|
| No Intervention: Control group<br>patients not given any intervention | |
