Collection of biological waste samples to advance oral and maxillofacial care

BIOlogical Waste Sample Collection for Progress in Oral and MAXillofacial Research

Observational I.R.C.C.S Ospedale Galeazzi-Sant'Ambrogio · NCT07024251

This project collects saliva, blood, and discarded tissue from adults having dental exams or oral and maxillofacial surgery to see if biomarkers like salivary irisin can help understand and diagnose oral and facial conditions.

What this trial studies

BIO-MAX is a five-year observational program at IRCCS Ospedale Galeazzi–Sant'Ambrogio that gathers biological material normally discarded during dental visits and elective oral/maxillofacial surgery. Samples include saliva, blood, and surgical waste tissue, which will be analyzed for biomarkers with a primary focus on salivary irisin. Researchers will examine how irisin levels vary with age, sex, lifestyle, and oral health, and will also profile other tissues to uncover disease mechanisms. Collected materials may be used to identify new biomarkers and to develop patient-derived laboratory models for future therapeutic testing.

Who should consider this trial

Good fit: Adults aged 18 or older who are attending IRCCS Ospedale Galeazzi–Sant'Ambrogio for routine oral examinations or elective oral and maxillofacial surgery and who can give informed consent are ideal candidates.

Not a fit: Patients under 18, those unable to provide informed consent, pregnant or breastfeeding individuals, and people with positive HIV/HCV/HBV/TPHA serology (if testing is required) are unlikely to participate or receive direct benefit from this protocol.

Why it matters

Potential benefit: If successful, this work could identify biomarkers such as salivary irisin that enable earlier diagnosis, improved monitoring, and more personalized care for oral and maxillofacial conditions.

How similar studies have performed: Collection of saliva and discarded surgical tissues has been used in other biomarker discovery efforts and early irisin research in metabolic and cardiovascular fields is promising, but applying irisin specifically to oral and maxillofacial conditions remains largely exploratory.
