Plain English summary of protocol
Background and study aims
The aim of this study was to evaluate the effects of platelet-rich plasma (PRP) injections, a method of accelerating orthodontic tooth movement, on the health of periodontal (gum) tissues.
Who can participate?
Patients aged 18 to 25 years with anterior teeth crowding.
What does the study involve?
Participants are randomly assigned to either the PRP group or the control group. The PRP group received PRP injections at 0, 7, and 14 days, while the control group received standard orthodontic treatment without additional interventions. Periodontal health was evaluated at the start of the study and after 4, 8 and 12 weeks.
What are the possible benefits and risks of participating?
This study will evaluate the effects of PRP injection to accelerate orthodontic tooth movement on periodontal health. There is a risk of not achieving optimal results in some cases but the study team can manage these cases with alternative methods.
Where is the study run from?
Tishreen University (Syria)
When is the study starting and how long is it expected to run for?
November 2021 to August 2023

| Ethics approval(s) |
Approved 07/12/2021, Tishreen University ethics committee (Lattakia, Lattakia, 0000, Syria; +963 (0)41420291; info@tishreen.edu.sy), ref: 2068 |
| Health condition(s) or problem(s) studied | Anterior teeth crowding |
| Intervention | Participants are randomly assigned to either the PRP group or the control group. Randomization was achieved using sealed envelopes containing the allocation sequence, ensuring that treatment assignments remained concealed from both researchers and participants until the designated phase of the study. The randomization sequence was generated by an independent academic specialist. The PRP group received PRP injections at 0, 7, and 14 days, prepared using the double-spin method, while the control group received standard orthodontic treatment without additional interventions. Periodontal health parameters were evaluated at baseline and at 4, 8 and 12 weeks. Aspartate aminotransferase (AST) levels were assessed at baseline, 1 hour, 1 day, 7 days, and 14 days. |
| Intervention type | Procedure/Surgery |
| Primary outcome measure(s) | Salivary aspartate aminotransferase (AST) activity measured using a spectrophotometer at baseline (before treatment), 1 hour after the start of treatment, 1 week after, and 2 weeks after treatment |
| Key secondary outcome measure(s) | Periodontal health parameters, including Periodontal Pocket Depth (PPD), Clinical Attachment Level (CAL), Bleeding on Probing (BOP), and Gingival Recession (GR), were recorded using a UNC-15 periodontal probe at baseline, 4 weeks, 8 weeks, and 12 weeks. |
