Effect of the Injectable Platelet-rich Fibrin on the Orthodontically Induced Apical Root Resorption Following Non-extraction-based Orthodontic Treatment in Adults: A Randomized Controlled Clinical Trial.

Damascus University·interventional·Posted Jan 20, 2026·Updated Jan 20, 2026

In Brief

A clinical study evaluating 4-time i-PRF injection group and Saline injection for Crowding of Anterior Maxillary Teeth. Completed, enrolled 36 participants across 1 site.

Detailed Summary

Mandibular incisor crowding is a frequent issue that prompts many adults to seek orthodontic treatment. The treatment may enhance patients' quality of life, facilitate dental plaque control, and improve the quality of periodontal tissue. However, this treatment is accompanied by several side effects, including resorption of the apical portion of the teeth. Platelet-rich concentrates, such as injectable platelet-rich fibrin, have been shown to have positive effects on both soft- and hard-tissue healing. They may serve as a beneficial self-derived material to prevent this complication.

Interventions

4-time i-PRF injection groupprocedure

I-PRF will be injected in 4 sessions at 28-day intervals. The injection will administered submucosally in the buccal region of the lower incisors, using 2 ml of i-PRF per session (0.5 ml per incisor). Orthodontic wires will be sequenced until they reach 0.019×0.025-inch stainless steel.

Saline injectionprocedure

Saline serum will be injected in 4 sessions at 28-day intervals. The injection will be administered submucosally in the buccal region of the lower incisors, using 2 ml of i-PRF per session (0.5 ml per incisor). Orthodontic wires will be sequenced until they reach 0.019×0.025-inch stainless steel.
