Oral and Maxillofacial Conditions

The goal of this clinical trial is to learn about the efficacy of using Bone Marrow Aspirate Concentrate (BMAC) during temporomandibular joint (TMJ) arthroscopy compared to standard arthroscopic procedures with corticosteroid (CS) injections in patients with pain (arthralgia) of the temporomandibular joint (TMJ) that has failed to respond to conservative treatment. The main question it aims to answer: Does BMAC injection reduce the amount of inflammation and structural damage in the TMJ? Researchers will compare BMAC injection to corticosteroid injections see if BMAC injection helps . Participants will : * Be randomized to receive either BMAC or CS injection during TMJ arthroscopy * Visit the clinic for 3 follow up visits over 6 months and answer questionnaires * have 2 MRIs of their jaw

The BIO-MAX (BIOlogical waste sample collection for progress in oral and MAXillofacial research) study, led by IRCCS Ospedale Galeazzi-Sant'Ambrogio, is a five-year observational research project aimed at improving the understanding and treatment of oral and maxillofacial conditions. Researchers are collecting and analyzing biological samples-such as saliva, blood, and tissues typically discarded during dental and surgical procedures-from adult patients visiting the hospital for oral exams or surgery. A key focus is the study of salivary irisin, a promising biomarker linked to diseases like diabetes and heart disease. By examining how irisin levels vary with age, gender, lifestyle, and oral health, the team hopes to establish baseline values and better understand its diagnostic potential. In addition to irisin analysis, the study will explore other waste tissues to uncover disease mechanisms, identify new biomarkers, and test future therapies using patient-derived laboratory models. Overall, BIO-MAX seeks to enhance diagnostics, improve patient care, and pave the way for innovative treatments in oral and maxillofacial medicine.
