NCT05214924

Brief Summary

The aim of the study is to evaluate the effectiveness of intra-articular platelet-rich fibrin (iPRF) injections in the management of moderate and mild cases of degeneration of the temporomandibular joints. This randomized, two-arm controlled trial will involve 42 adult patients diagnosed with mild or moderate degeneration of the temporomandibular joints on the basis of clinical examination and magnetic resonance imaging or computed tomography. Qualified study participants will be randomly assigned to two groups. The studied group will receive two injections of iPRF with an interval of 30 days, while the control group will receive injections of platelet-rich plasma (PRP) during this time. Each subject will be tested on the day of the first injection (D0), on the day of the second injection (D30), and then 60 (D60) and 12 (D120) days after the first injection using MRI/CT, Doppler Hi-dop, clinical examination and surveys.

Outcome Measures

Primary Outcomes (1)

  • The effectiveness of intra-articular platelet-rich fibrin (iPRF) injections on TMD symptoms reduction assessed by clinical examination in accordance to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) protocol with DC/TMD examination form.

    Each patient will undergo DC/TMD protocol-based clinical examination before and after injections using DC/TMD examination form assessing incidence of pain and disfunction in temporomandibular joints, masticatory muscles and surrounding structures.

    Up to 3 months

Secondary Outcomes (8)

  • The effectiveness of intra-articular platelet-rich fibrin (iPRF) injections on the jaw mobility assessed by jaw mobility measurement with professional ruler (millimeters).

    Up to 3 months

  • The influence of intra-articular platelet-rich fibrin (iPRF) injections on intra-articular sounds assessed using Doppler Hi-dop (Hz).

    Up to 3 months

  • The influence of intra-articular platelet-rich fibrin (iPRF) injections on pain in temporomandibular area assessed using Graded Chronic Pain Scale.

    Up to 3 months

  • The influence of intra-articular platelet-rich fibrin (iPRF) injections on reduction of pain in temporomandibular area assessed using TMD pain screener questionnaire.

    Up to 3 months

  • The influence of intra-articular platelet-rich fibrin (iPRF) injections on reduction of pain in temporomandibular joints assessed using Pain Numerical Rating Scale.

    Up to 3 months

  • +3 more secondary outcomes
