Assessment of Injectable PRF Versus Dextrose Injection in Temporomandibular Joint in Anterior Disc Displacement With Reduction
Sponsor: Cairo University
Summary
This randomized clinical trial aims to compare the accuracy and effectiveness of injectable platelet-rich fibrin (I-PRF) versus 25% dextrose prolotherapy injected into retrocondylar tissues in patients with anterior disc displacement with reduction of the temporomandibular joint. The study will evaluate improvement in disc position, pain, mouth opening, and clicking sounds following treatment.

Interventions
PRF treatment group
Participants in the I-PRF group will receive 1.5 cc of injectable platelet-rich fibrin (I-PRF) injected into the retrocondylar tissues of the temporomandibular joint at 0, 2, and 4 weeks. Approximately 10 mL of blood will be withdrawn from the patient's antecubital fossa using vacuum tubes and centrifuged at 700 RPM for 3 minutes for I-PRF preparation. The resulting I-PRF will be transferred using a sterile 22-gauge 3 mL plastic syringe and injected into the retrocondylar tissues. In cases of bilateral involvement, the procedure will be repeated on the opposite side.
Dextrose 20% Prolotherapy
Participants in the control group will receive 1.5 mL of 25% hypertonic dextrose solution injected into the retrocondylar tissues of the temporomandibular joint at 0, 2, and 4 weeks. The solution will be mixed with 0.2 mL of local anaesthetic solution containing 2% mepivacaine hydrochloride with 1:20,000 levonordefrin. The substances will be injected under aseptic conditions using a 22-gauge needle. In cases of bilateral involvement, the procedure will be repeated on the opposite side.
