Umbilical and Placental Derivatives in Temporomandibular Joint Treatment: A Systematic Review.

: This review aimed to gather and summarize the existing information on the clinical application of allogeneic umbilical and placental derivatives in the treatment of temporomandibular joint disorders. : Research on the impact of the use of umbilical and placental derivatives on reducing pain and improving mobility in the temporomandibular joint was included in the article. Medical databases, including ACM, BASE, Cochrane, Scopus, Google Scholar, ClinicalTrials.gov, and PubMed, were searched. The final search was conducted on 20 October 2024. : Out of the 43 records found, 5 were considered eligible for further analysis and showed that the use of placental and umbilical derivatives has the greatest potential in the treatment of ankylosis. The intra-articular administration of these tissues into the TMJ brings beneficial results, but they are similar to other, parallel methods, such as PRP or corticosteroids. : The studies discussed may guide researchers in expanding clinical trials, particularly by including more patients with TMDs, and have promising potential in ankylotic disorders, where amniotic membrane use has shown clear benefits.
